圣夜学园的传奇小学生，日奈森亚梦，因为不擅于交谈，因此在学校被套上一层很酷的形象。其实他一直想要让自己更外向并展现出真正的自己。这天，她祈祷自己可以改变自己，突然在自己的床上出现了三颗蛋？

亚梦一直对自己向王子告白的事感到懊悔。第二天，她去学校的时候虽然引起一阵骚动，但却感觉到和大家更亲近了一点，亚梦也因此而感到开心。这时候守护之星的其中一人藤咲突然出现，邀请亚梦参加皇家庭园茶会。

不想过于引人注意的亚梦拒绝参加守护之星，但没想到却是反效果。在回家的路上，抚子突然出现在她眼前。抚子为了让亚梦加入守护之星，因而邀情她到唯世家里玩，并且跟亚梦决定要带亲手做的饼干去…。

亚梦终于成为新的守护之星的成员，也开始了一连串的特训。有一个名叫鸠羽雪的女孩子因为父亲工作的关系，即将要转学到美国，因此心里感到极度不安。此时一个奇怪的身影出现在小雪的背后而且还露出了邪恶的冷笑…

守护之星的成员相马空海正在练习足球，练习场上还有一位叫山田的球员和空海的实力相当，在练习完毕之后，教练发表先发球员名单，但是名单里面没有山田的名字。于是失望的山田身边开始弥漫一股黑暗的气息…

在某一个星期日亚梦的爸爸妈妈留下一张纸条，要她照顾妹妹一天。没办法的亚梦只好带着妹妹一起到学校去。来到学校的亚实被唯世的守护甜心辉石找去参加校内大探险，而这个寻找守护胚的冒险究竟会变成什么样子呢…

守护之星的工作结束之后，弥耶找亚梦一起到芭蕾教室来看自己的舞蹈，这里有一位天才少女-姬川舞香，她在练习的时候不小心受伤了，一向非常自傲的舞香禁不起这样的打击，而心灵之蛋也开始出现了一股奇怪的黑影…

五年月班的渡会美咲因为喜欢唯世，所以找亚梦组成共同作战组织。当亚梦和这位外向活泼的美咲在一起以后，慢慢的也开始觉得很愉快，两人为了让恋爱咒语可以顺利进行到处奔走，而最后的结果是…

亚梦这一天要到抚子家过一夜，看到抚子为了公演而练习舞蹈的亚梦，不自觉的也爱上了这个舞蹈，这一天时间过的很快一下子就到了晚上，亚梦洗好澡以后一个人走在回廊里面，听到了远处传来一阵阵奇怪的声音…。

亚梦和守护之星的成员一起出去买挂在圣诞树上的饰品，在回家的路上，碰到黑夜和他的野猫朋友恶作剧抢走舒舒的东西，舒舒在追他们的时候自己也迷了路，因为亚梦一直等不到舒舒回家，所以决定要出去寻找舒舒…。

守护之星成员到空海的爷爷家，一群人在雪山玩耍，又在寺庙里面打扫玩的不亦乐乎。第二天，一群人到温泉街上去买一些礼物的时候，大家藉故离开只剩下唯世和亚梦两个人，两个人在回家的路上谈起「喜欢的人」这个话题…

在圣诞夜的街道上，亚梦在电视墙上看到了和几斗在一起的新人偶像歌手，星名歌呗。在回家的路上，公园传来一阵优美的音色，亚梦被那音乐吸引了过去，可是没想到出现在眼前的人居然是…

守护之星成员决定要去参加新年晚会，可以出席这个晚会的，都是一些非常受欢迎的偶像明星，当亚梦看到几斗正想前往询问关于圣诞节及Easter的事时，却发现他和日本知名的大企业Easter的人出现在舞台后面…

过年期间，圣夜小学五、六年级学生前往雪山参加『滑雪教室』活动，而担任指导教练的居然是只有11岁的鸟居美冬，她是国内实力坚强选手之一，可是只要到正式比赛开始的时候她就会非常紧张…

眼看着比赛就要开始了，可是美冬却是越来越害怕，非常关心美冬的亚梦突然发现守护甜心雪贝不见了。守护之星们分头寻找，最后在一间小屋里面，发现有一台机器前面发现的守护蛋居然是一个×恶蛋！？

引起大家注意的少年魔术师Zero的真实身分是圣夜小学四年星斑的长仓拓哉，拓哉是一个有实力的魔术师，可是他的经纪人却是喜欢用一些骗人的手法表演华丽的魔术，拓哉为了这件事情相当烦恼…

亚梦被选为班上参加演讲比赛的代表，山吹因为嫉妒而被二阶堂操纵，不仅让她从中挑拨离间，让空海对亚梦产生怀疑更对唯世失去信心，就在此时空海的守护甜心大知变得十分痛苦…

本来大家说好要一块儿去水族馆的，没想到最后竟演变成亚梦和唯世的第一次约会？！亚梦紧张的手忙脚乱，半路上还冒出个小女孩跟×恶蛋来搅局，就在追捕×恶蛋时，黑夜和几斗也突然出现…

爸爸妈妈第一次见面的照片不见了，看到妈妈难过的样子，亚梦决定帮她到拍卖市场找找看是不是有办法找回来，不料却被黑夜误会以为藏着守护胚的秘密，让亚梦寻找照片之路无端多了许多的阻碍…

空海的姐姐诗音就要离开家乡到远方了，空海绞尽脑汁想要帮她挑选一个礼物，正当他和亚梦在讨论时，却发现卖场里竟然出现大量的×恶蛋，奇怪的是偶像星名歌呗也正好在这里举办小型的演唱会…

亚梦和米奇起了一点小争执，竟让二阶堂有机会把亚梦的三个守护甜心一起绑走了，虽然在黑夜的协助下，亚梦找到了二阶堂，但在没办法甜心变身或甜心出击的情况下，要如何搭救小兰她们三个呢？

亚梦的守护甜心们被二阶堂抓走了，守护之星为了寻找她们的下落，决定请占卜大师冴木老师帮忙，在一阵手忙脚乱当中，老师凭着她的直觉居然真的找到了舒舒她们，而就在此时亚梦遇到歌呗….

亚梦一个人来到了二阶堂的工作室，就在舒舒要被拿来实验之时，守护之星们全都赶来帮忙，而二阶堂所收集的×恶蛋因能量外洩，而形成一个巨大机器人，可是舒舒居然阻止亚梦打败它，原来她看到了二阶堂年轻时的梦想….

今天是写生大会的日子，主题是校园中最喜欢的地方，亚梦为了寻找适合的地点在校园中四处走，也因此想起了过去几个月来生活上的大变化，原本没有朋友酷酷的她，因为守护蛋的出现让她成为守护之星的成员…

抚子决定离开日本到欧洲去学习舞蹈，但她不忍心告诉亚梦，于是要求唯世他们暂时先不要说，因为感情上的烦恼想要找抚子商量的亚梦一个人来到了抚子的家，却踫到一个自称是抚子双胞胎哥哥的男孩…

继抚子出国，空海也即将要毕业，亚梦面对接二连三的别离心情汤到了谷底，当她外出散心时竟凑巧遇到了几斗，几斗带她到一个即将要拆除的游乐园，亚梦在那里完全抛开了束缚尽情享受乐园带来的欢乐…

正当亚梦抱着全新开始的心情准备迎接新学期时，新来的转学生真城璃茉却让亚梦陷入了沮丧的心情，在捕捉×恶蛋差点失手之后，又听到班上男生对自己的评语，加上璃茉对她努力示好不屑一顾，让亚梦完全迷失了自己…

随着抚子和空海相继离开，新的成员也终于正式登场，皇后果然是超级美少女璃茉，骑士则是由海里担任，在自己的蛋出现××然后又搞丢的亚梦，在忐忑不安中觉得守护之星少了她似乎没什么关系….

心情低落的亚梦对守护之星Joker的职位毫无信心，这时空海突然出现，他看到亚梦这么沮丧，决定要帮她打气，就在亚梦觉得心情好多时，歌呗居然冒出来向她挑战，此时，被歌呗嫌弃的绘琉居然跟亚梦甜心出击了…

今天是一年一度球技大赛的日子，就在亚梦好不容易说动璃茉站上球场时，居然出现了一颗×恶蛋，亚梦只好靠净恶之心啦啦队员的装扮来掩饰她的猎蛋行动，她拼命努力的模样让璃茉也开始打开了心房…

这个星期天，弥耶突然邀请守护之星的成员到她家召开临时会议，原来她真正的目的是希望大家一起来帮忙照顾她的弟弟小翼，看到弥耶因为突然升格当姐姐不适应，亚梦也不禁想起自己当年也是如此…

平时总是不太爱说话的璃茉，让亚梦觉得她的沉默似乎是有什么原因，而且她总是不愿意甜心变身这也是亚梦一直感到疑惑的事，直到和璃茉一起整理班级图书时才赫然发现原来璃茉是一个很爱耍宝搞笑的人…

这一天亚梦和唯世两个人单独出门，紧张又期待的亚梦在守护甜心们的加油声中展开了愉快的一天，而肩负秘密任务的海里对于亚梦似乎并不只有间谍跟踪目标的想法，亚梦的一举一动似乎牵动着他心里面某种感受…

学校附近有一栋鬼屋，守护之星为了同学的安全决定去一探究竟，想不到一进门就开始出现一连串奇怪的现象，这时小兰她们发现一个半透明的守护甜心，同时璃茉也发现那个总是带着画具的男孩原来有着不为人知的伤心回忆…

亚梦一家人受邀参加表哥阿修的结婚典礼，然而他的未婚妻绘里子在婚礼前一天表示她的心意改变了?!阿修沮丧的心情让他的守护蛋变成了×恶魄，曾经视他为初恋的亚梦鼓励他别放弃自己的梦想，帮助他重拾信心…

校园里来了一位作风夸张华丽的王子修罗耶，他公开表示要在校园寻找他的王妃，这个消息让全校女生陷入了疯狂，随后他又表示来圣夜的另一个目的是寻找守护胚，不过他却企图用其它理由来掩饰他心中真正的愿望…

三条制造假的守护胚企图控制修罗耶来做坏事，而性情大变的他对父亲又爱又恨的情感竟成了邪恶的力量，守护之星集合力量一同对付假守护胚的×恶魄，修罗耶也在亚梦的直言之下终于愿意面对理想中的自己…

由佳里让海里将亚梦手中的Humpty Lock抢过来，但面对亚梦，海里觉得很为难，想到姐姐说调查到信息后就会还给亚梦，海里打电话将亚梦约了出来，不过亚梦没带Lock，因为Lock不见了。与此同时，守护甜心会议在皇家花园召开，绘琉说自己无论如何都想找到胚胎，所以她把亚梦的Lock也带来了。

最近在学园里流传的最热闹的传闻，就是只要听愿望CD，不管想要什么都能得到。唯世对亚梦说他其实也想听听愿望CD，想让自己变得坚强。唯世的奶奶是个严肃而有威严的人，而这样的奶奶是他最喜欢的，奶奶从小就鼓励他成为坚强的人，年迈后因为生病变得虚弱，而唯世为自己始终没有长进而感到迷惘，掉进了黑色CD的陷阱。

由佳里又给了海里新任务，新的计划是要以歌呗和方块的力量来摧毁圣夜小学，因此他要做的是将剩余的愿望CD发给圣夜小学的学生。璃茉妈妈让璃茉提交退部申请，因为参加社团活动导致回家时间不稳定，增加了很多不必要的麻烦。守护者的成员决定回收愿望CD，亚梦让璃茉负责四年级的回收工作，璃茉离开时，退部申请掉了出来

海里想要把黑色CD还给由佳里时，被亚梦等人撞见，他承认了自己是复活社间谍的身份，亚梦等人很是震惊。二阶堂在街上偶遇海里，海里很感谢他以往一直没有拆穿自己的身份，二阶堂却说他是想看看老诚又冷静的海里跟守护者们扯上关系后会有何变化。亚梦还是想要见海里一面，她相信跟守护之星的同伴在一起时的海里才是真正的海里。

决战前夕，唯世来找亚梦，向她说出了自己与几斗、歌呗之间的往事，并拜托她拯救歌呗。在歌呗即将踏上飞机时，亚梦等人出现了，歌呗跟依琉形象改变对阵亚梦，打的激烈时绘琉呼唤依琉，让她跟自己同心协力拯救歌呗，歌呗流露出嫌弃依琉的表情，依琉便解除变身向亚梦飞去，并且跟亚梦形象改变。

亚梦坚定了自己的决心，终于得到方块的认可，俩人形象改变，光芒照亮了天际。歌呗看到甜心相继离开，顿时无力感由心而生，气氛沉重，这时亚实出现，无厘头的搞怪打破了凝重的气氛，也让歌呗重拾信心，唱出了埋藏在心底的歌声。三条藏在飞机里的坏蛋发生暴动，大面积袭击亚梦等人，亚梦、歌呗形象改变，并肩作战。

暑假期间，亚梦不禁想起不久前自己还是刚升入六年级的学生，就在这短短的几个月时间里，自己与璃茉成为了好朋友，与海里也相处融洽，三条与歌呗也离开了复活社。得知三条成立了新公司，守护之星的人前来帮忙，歌呗跟亚梦一如既往，一见面就吵得不可开交，其实心里都认可彼此。大家在一起庆祝公司成立，却意外得知海里要回故乡的消息。

圣夜学园决定参加合唱比赛，开始决定伴奏钢琴以及独唱的人选，一番比赛后，四年星组田中真理萌担任钢琴伴奏，独唱选手则选定为亚梦。诚一郎音色不准在校园里独自练习，被田中撞见，田中也要练习琴技，便邀请诚一郎一起练习。沙绫不服气田中被选为钢琴伴奏手，便处处找她的麻烦，田中不堪心理压力，心灵之蛋发生了变化。

璃茉传简讯给亚梦约她见面，原来璃茉得到两张杂耍剧场的门票，邀请亚梦一起去。俩人路过公园，遇见了一个想成为搞笑艺人的女生小都，璃茉看到她那股热情，决定帮助她，接来来对她进行了搞笑剧场甄选大会的特训。比赛前小都得罪了作为裁判的胡次郎老师，比赛开始了，轮到小都上场，表演过程中遭到了胡次郎的嘲笑，心灵之蛋被蒙上了黑色。

由佳里生病了，她拜托亚梦充当一天歌呗的经纪人，刚一到电视台，就有人通知歌呗的出场被取消了，随后亚梦才知道退出复活社的歌呗的处境大不如前。亚梦不放弃，一家一家寻找着演出机会，但是俩人如何努力也没能求到表演的机会。俩人在路边休息，突然出现一只坏蛋，亚梦的一番话感动了歌呗，也让歌呗找到了她的新舞台。

唯世为了改掉弥耶总是爱撒娇、爱依赖别人的习惯，于是请空海替她进行特训，目的是希望她能够从中得到成长的启发。这时三年星组养的鹦鹉丢失了，向守护之星求助，亚梦形象转变画出了鹦鹉的图案，空海建议将这个任务交给弥耶一个人来处理，从一开始就完全不能接受的弥耶是否可以完成这个艰难的任务呢？

亚梦在回家途中听小提琴声，循声找去发现果然是几斗，还不由自主的唱了起来，结果琴弦突然断了。几斗、亚梦来到小提琴修理店，店主是一名手艺精湛的小提琴师傅，而他的女儿琴音感染到父亲的热情，也立志要成为一名杰出的小提琴师傅，但是当她头一次获得名演奏家纱江子小姐的赏识帮她处理琴时，竟一时大意造成琴身的损伤。

九十九等人吸取失败的教训，改良版的胚胎二号研发成功，启动后发生异常，坏蛋受到影响全部都飞了出去，而研究所也发生了爆炸。上司打来电话，让九十九去调查关于几斗的事情，九十九趁几斗不注意，将跟踪器装在了几斗身上。另一方面，守护甜心们去魔王的城堡寻找胚胎，亚梦等人发现甜心不见了，为了寻找他们，也一起去往魔王的城堡。

复活社的后辈把邮件错发到二阶堂老师那里，说今晚绝对会出现胚胎！二阶堂将这一消息告诉了亚梦。几斗也被社长口中的大人召见，得知了胚胎会出现的消息。亚梦等守护之星的成员期待着胚胎的出现，在等待的同时，每个人心中也开始想著自己的愿望，这时亚梦收到手机简讯，几斗约她在老地方相见，殊不知，这一切都是一场阴谋。

甜心们在皇家花园聚会，大家让奇迹说些好玩的话题，要是说不出来的话就无法维持身为王的身份，这让奇迹感受到了巨大的压力。方块突然出现在皇家花园，她想了解下在她出生前，关于大家的故事。从小兰开始，她讲述了初遇亚梦以及亚梦慢慢地耀眼地成长的故事，随后甜心们也各自讲述了自己主人的故事。

亚梦与甜心们来到理事长办公室，第一次来办公室一定要做的事就是抽卡牌，小兰抽到了王，寓意闪耀着光辉的小星星，那光辉笔直地照亮黑暗，引导着迷惑的星星。亚梦想要在雨下大之前回家，结果还没到家雨就下大了，无奈之下她只好先躲到树下避雨，这里是她第一次听几斗拉小提琴的地方，她轻唤几斗的名字，没想到几斗竟然出现了。

美琪在麻奈美家附近感受到了守护蛋的气息，第二天亚梦去麻奈美家给她送曲奇，美琪、小丝、小兰均感受到了守护蛋，亚梦四处寻找发现一个女孩，她就是转学生露露·堂·莫鲁斯露，她傲慢的态度让亚梦火冒三丈。莫鲁斯露竟然是复活社的成员，她所制造出来的魔法珠宝可以将佩戴者身上的心灵之蛋抽出。

亚梦在便利店门口遇到了一名叫做蜷川瞳的女孩，她是歌呗的粉丝，得知亚梦跟歌呗认识后想让亚梦带自己见歌呗一面，亚梦耳根子一软便答应了。亚梦去事务所拜托由佳里，结果被拒绝，离开时在公寓外遇见了歌呗，便向她说出了请求。小瞳很想像歌呗一样登台唱歌，但也不想放弃网球，犹豫期间目光转向窗外，看到了站在楼下的露露。

抚子换回男装后空海很讶异，但唯世说这才是他的本来面目，因为藤咲家是日舞世家，为了能够跳起来更像女性，所有藤咲家的男孩子从小就要以女性的身份面对外人，而他本来的名字叫做藤咲凪彦。复活社开始了新的阴谋，理事长叫来空海一起劝说凪彦，前代Q作为现在的J也是一件很有趣的事情

岩垣前辈要来圣夜学园进行交流学习，因为他讨厌可爱的东西，所以学校禁止学生带可爱之物来，结果亚梦等人忘记了，带来了新买的激萌喵，被岩垣看见了。亚梦见到了一个可爱的小鹿挂饰，她跟璃茉、弥耶去皇家花园途中，遇到了岩垣，三人心中充满恐惧感四处逃窜。亚梦被岩垣堵在了回家的路上，他告诉亚梦她捡到的小鹿是他的。

亚实带小兰、小丝、美琪去幼稚园了，因为今天是守护甜心会议日，奇迹与其余甜心去幼稚园找她们，阿夜在公园看到奇迹等人后也尾随而去。幼稚园的小朋友看到这么多甜心很开心，阿夜挑衅奇迹，奇迹询问他是否跟谜之蛋有关系时，被粘土王子诚君一把抓住了，诚君让奇迹做他的模特。小朋友跟甜心玩的很开心，只有诚君是个例外，而这时娜娜也出现了。

歌呗的努力被认可，事务所允许她开演唱会了，绘琉来找亚梦。希望她可以帮忙将歌呗的演唱会炒热，虽然亚梦已经预见歌呗的态度，不过还是答应了。果不其然，对于亚梦的帮助歌呗一脸不屑，于是亚梦就说如果几斗的小提琴配上歌呗的歌曲，肯定是完美组合。亚梦去找几斗希望他可以给歌呗伴奏，却从阿夜那得知了几斗小提琴丢失的消息。

今天的幸运星占卜节目中，好运位居第一的是天秤座，特别是恋爱运非常好，正在单相思的人如果去告白的话，思念可能会传达到，身为天秤座的亚梦脑海中瞬间浮现了唯世与几斗的面孔。运气最差的是狮子座，露露听后略受打击。同班的小历占卜也意外的准，亚梦的占卜结果是如有想要的东西现在决断可能比较好，这难道是指现在是告白的时机吗？

平子搬家时遗失了守护蛋，幸好被亚梦捡到，等守护蛋孵出来后就可以知道她的主人了，甜心们费劲折腾守护蛋也没动静，最后还是方块出马蛋里的甜心才破壳而出。她叫小闪，因为主人是一个心地善良但羞涩的女孩，她许下了不论何时都能让自己和朋友露出灿烂笑容的愿望，所以小闪才可以这么闪亮的热心帮助别人。

皇家花园大扫除时，发现了一年前的合影，弥耶等不知情的人都觉得凪彦跟抚子很像，亚梦跟抚子身为密友，之间却没有任何联系让弥耶很意外，而密友这一词戳痛了璃茉的心。璃茉最近看起来闷闷不乐，嘻嘻的搞怪璃茉也视而不见，为了让璃茉开心起来，大家决定来一场微笑大作战，亚梦也拉着凪彦加入了进来。

明天就是圣诞节了，妈妈想要举行一个圣诞派对，与邻居们分享欢乐，亚梦一家也在邀请当中。露露向亚梦介绍了自己的甜心娜娜，她让娜娜好好招待亚梦，自己则忙前忙后，她想要让妈妈过一个完美的圣诞节。亚梦在露露房间看到了她给妈妈做的漂亮的项链，露露去给妈妈送礼物时，看到了妈妈跟爸爸在表演圣诞老人与驯鹿后，失落的离开了。

亚梦等人去神社进行新年参拜，遇到了要参加神社的演艺大会的海原兄妹，虽然已经练习一年多了，但技术还是不够娴熟，璃茉对艺术的严谨态度瞬间爆发，决定指点他们。几斗很安静听父亲训话，这是很少见的事，原来他这样做是为了让阿夜顺利偷出小提琴的钥匙，几斗刚一触碰到小提琴，警报声就响了起来。

亚梦洗漱完毕准备上床睡觉，却发现几斗在床上睡的正香！阿夜告诉亚梦，他跟几斗从复活社偷回小提琴后，几斗又冷又困，险些在寒冷的街头睡着，阿夜跟几斗形象改造后，坚持走到了亚梦家中，然后沉沉睡去。雪下了一夜，第二天到处都是白茫茫一片，亚实吵着要堆雪人，耐不住亚实的纠缠，亚梦带她去学校堆雪人，而几斗还在亚梦的房间睡着。

最近出现的猫耳少女给大家造成了困扰，唯世担心与复活社有关，提醒大家多留意一下。在放学回家的途中，大家在公园看到了猫耳少女，猫耳少女不小心踩断了自己的尾巴，大家才知道传说中的猫耳少女只是变装而已。大家离去后亚梦上前与她进行交谈，她叫做千代子，她想以理想的形象来帮助别人，伪装成猫耳娘后就会觉得自己无所不能。

几斗离开后亚梦状况百出，大家问她是否有烦心事，亚梦解释说有只流浪猫来家里呆了几天后不见了，自己有些担心。电视上播放有关UFO的消息，亚梦还是显得心不在焉，而娜娜却显得格外兴奋，她在河边画了神秘怪圈，吸引了大家的注意。露露、娜娜在公园遇到了一个叫做那由他的女孩，她说只要满心许愿，感应到的UFO就会出现。

因为山吹父亲要将集团转移到海外，她也要转学去洛杉矶，所以她为此举行“再见了，山吹沙绫”的大型欢送会，请大家去参加，不过欢送会一般会是自己给自己开吗？璃茉心中充满了疑问。欢送会上，山吹要跟亚梦举行淑女比赛，三局定胜负，亚梦歪打正着竟取得了前两局的胜利，但山吹却说，决出最后的胜负要得3分，于是开始了第三局的比赛。

亚梦、唯世告诉璃茉皇家花园漏雨，所以要修补屋檐，今天禁止入内，拜托璃茉在教室里工作，亚梦则借口理事长有事找她和唯世，于是便迅速离开了。今天是璃茉的生日，守护者其余人在皇家花园进行着派对的准备工作，这时叫做雾岛的男孩来到了皇家花园，他说自己喜欢璃茉，虽然已经给她写了情书，但还是想当面给她告白。

情人节就要到了，亚美被妈妈跟亚实拖去手制巧克力教室，在这里也遇到了同校的由纪奈，她要参加明天学校举行的巧克力糖果竞赛，所以来这里学习。手工老师品尝了由纪奈做的巧克力，并指点了她。亚梦说自己做巧克力是要送给朋友们的，而由纪奈则说要是优胜的话想送给同班同学大辅，不过去年送给他时被拒绝了，因为大辅说自己最讨厌巧克力了。

亚梦、唯世被选中去参加全国小学生高峰会议，海里作为执行委员，在名单中看到了亚梦和唯世的名字，略显震惊。美琪发现了躲在暗处偷看的海里，想要告诉亚梦却被海里抓住，不过在奇迹的大声呼喊下，亚梦、唯世和海里三人见面了。久违了的三人坐在一起尴尬感油然而生，甜心们看到后相互追逐嬉闹才缓和了紧张感。

亚梦在街道遇到了一位老婆婆，她与生俱来的震慑力让亚梦叹为观止，她向亚梦打探莫鲁斯露家，原来她是露露的奶奶。娜娜来亚梦家告诉她露露有麻烦了，露露奶奶追求完美主义的心态让人压力丛生，娜娜怕露露又会变回以前那样，所以来亚梦家寻求帮助，不过亚梦告诉娜娜奶奶肯定会为露露好好考虑的。

小兰吃掉了美琪的蛋糕，俩人吵了起来，在一旁的小丝也被俩人认为是机灵鬼，三人闹起了矛盾。守护甜心会议中三人再次闹翻，小兰、美琪相互不理对方，小丝一气之下也离开了皇家花园。小丝遇到了曾有一面之缘的女孩，她在研究各种料理，她的愿望是想成为美食评论家，其实心里还是想成为厨师。露露发现了这个犹豫不决的女孩，给了她魔法宝石。

亚梦将几斗捡回家，又开始了在同一屋檐下的惊险相处。唯世意外来访，亚梦急忙跑回房间将几斗、阿夜丢进了柜子里，还警告他们不许发出声音，然后将唯世带进了房间。今天是白色情人节，虽然亚梦在情人节时将送给唯世的巧克力弄丢了，但唯世还是给了她回礼，并且进行了一场深情告白。

歌呗来亚梦家，想找她谈谈关于几斗的事情。俩人一起去了拉面店，露露和娜娜碰巧看见了俩人，便躲在店门口偷偷观察俩人。歌呗要了一份米饭，却被天才小学生美食家丸山斥责这是对拉面师傅的不尊重，他高谈阔论一番后，歌呗淡然的反问他这样是否真的会很美味，然后跟亚梦离开了，而露露和娜娜也看到了迷茫的丸山。

在守护者会议中，藤咲说他昨晚听见了不可思议的声音，出去查看情况时在街上发现了许多内心空洞的人，他怀疑复活社在进行着谜之蛋的同时，也在进行着其他的计划。亚梦和唯世在公园看到了藤咲说的那群人，也听见声音，唯世说那是小提琴的声音。复活社的作战开始了，用小提琴操纵几斗，通过琴声吸引大量坏蛋，从而发现并捕捉胚胎。

放学后唯世邀请亚梦一起去车站前的美术馆参观插画展览会，约定好四点在喷泉前面见面，亚梦兴高采烈回到家，看到几斗后好心情被破坏了一半。趁爸妈不在家，亚梦让几斗去洗澡，不料这时妈妈回来了，亚梦只好骗妈妈说自己在洗澡，不让她进来，几斗洗好后俩人打算悄悄回房间，结果被妈妈逮了个正着。

亚梦来到皇家花园，发现唯世还没有来，随后奇迹来告诉大家唯世生病了不能来，亚梦听后瞬间松了一口气。弥耶提议大家一起去探病，这让亚梦感到不知所措，藤咲看到亚梦为难的表情，便说让亚梦一个人代表大家去。途中亚梦遇到了露露，她看到亚梦无精打采的想关心下，娜娜知道露露碍于面子不好开口，于是跟露露形象改造后，鼓励了亚梦一番。

阿夜告诉亚梦几斗被复活社的人抓住了，让亚梦帮忙一起救出几斗，不过亚梦想起几斗对唯世所说的过分的话语，拒绝帮助阿夜。相马买东西经过公园，发现唯世独自坐在那，便邀请他去家里，经过一番谈心后，唯世打开了心结。亚梦收到歌呗的简讯，明白自己不能再消沉下去了，形象改造后跟阿夜一起去寻找几斗。

在唯世的呼唤下，几斗短暂的恢复了神智，他让亚梦别接近他，随着音叉波动的加强，几斗再次迷失了自我，这时复活社的专务出现了，命令几斗消灭掉亚梦及唯世。复活社的出现，让唯世、亚梦明白几斗是被控制了，他俩使用铂金之心，将坏蛋重新变回心灵之蛋，胚胎也意外的出现了，亚梦向着胚胎飞去，快要到达之时胚胎突然发出了耀眼的光芒。

精疲力尽的阿夜回到皇家花园后沉沉睡去，亚梦等放学后发现了他，对于奇迹的训斥阿夜并没有反驳，这让大家感觉很惊讶。守护者们得知几斗被复活社软禁后，弥耶提议直接闯进复活社去寻找几斗，不过被门卫赶了出来，于是他们去找二阶堂老师，请教他如何能够潜入复活社。阿夜跟奇迹顺利进入复活社，悄悄尾随在专务身后，寻找着几斗的下落。

亚梦在草坪上休息时差点被棒球砸到，幸好月班的奈津子及时接住了球。奈津子带亚梦体验棒球，投手藤田丝毫没有放水，亚梦直接被三振出局。奈津子的梦想是当投手，她与藤田可是竞争对手，看到奈津子认真的表情，亚梦叫来相马帮她进行特训，不料奈津子表现失常，原来她只要看到前面有球棒就会感觉紧张，没法好好投球。

弥耶给大家看了世界音乐博览会的宣传单，亚梦看到小提琴图案想起了几斗，心情有些低落，大家猜测或许几斗也会出现在博览会上，在弥耶的鼓动下，大家决定一起去参加博览会。阿夜在吃饭时感受到了几斗的气息，难道是他的错觉吗？露露也出现在了博览会上，她变装后跳起了舞蹈，迷惑了复活社的人，停止了音叉的工作，救出了几斗。

二阶堂老师让同学们以“将来的梦想”作为题目写篇作文。亚梦跟同学闲谈互相问写的是什么，真奈美的梦想是开一家花店，亚梦则盗用了藤咲的希望珍惜追逐梦想的时间，而若莱却说她想当一名像二阶堂老师一样的老师，亚梦很惊讶，若莱告诉她，二阶堂不但会在放学后辅导学习不好的学生，而且还会对烦恼和悲伤的孩子们伸出援手。

弥耶瞒着大家报名了，所以Pretty杂志将会登载关于守护者的文章，今天就要来学院摄影取材。樱井优亚听到亚梦的名字后有种熟悉感，随后得知亚梦的全名后才想起来她和亚梦是幼儿园同学，不过神经大条的亚梦硬是没有一丁点的记忆。塞西突然出现在大家面前，原来她是优亚的守护甜心，不过优亚看到塞西后竟然说她惹人烦，这究竟是怎么回事呢？

优亚在现场演唱会时无法发出声音，决定放弃唱歌。藤咲告诉优亚塞西一直在关心她，如果她放弃了唱歌，塞西就会消失。自从演唱会事件后，亚梦等人再也没见过优亚，这时塞西突然出现，她说优亚在别人的面前唱不了歌，只是在独自一人的时候唱歌。虽然优亚只跟亚梦说过一次话，却能让优亚一直铭记到现在，亚梦相信优亚定能够再次歌唱。

娜娜发烧了，露露纠结了很久之后才决定打电话向亚梦求助，但亚梦的甜心们身体倍棒，没有生过病，她也不知道该怎么办。露露看到生病的娜娜很是心疼，这时门铃响起，亚梦带着甜心们来探望娜娜。按照小丝的食谱，露露做了颜色奇怪的汤，经过亚梦试吃才端去给娜娜，小兰、小丝、美琪变装为甜心护士照顾娜娜，露露跟亚梦出去买娜娜爱吃的零食。

Amu and her Guardian Characters are on their way to school when they see a girl taking water to a flower. Amu comments on how kind that is. The girl gets flustered, and trips and almost crushes the flower, to be saved by Amu. The two introduce themselves. The girl's name is Rikka and she just transferred to Seiyo. Amu gets surprised when she's able to see Ran, Miki, Su, and Diamond. On the way to school, Amu and co. try to explain everything to Rikka, who lost attention while seeing a butterfly. In the Royal Garden, Amu tells the Guardians about her meeting with Rikka. Then, commotion starts outside and the Guardians check it out. Rikka is trying to save a cat from a tree branch. The branch breaks, and Rikka clutches the cat in fear as she falls.

The anime starts with Rikka, the new transfer student, waking up with dozens of X Eggs trying to wake her. She tries to purify the eggs from remembering Amu doing Open Heart in the previous episode, but failed. When she was walking to school she found yet another X Egg and tries to take care of it. In the Royal Garden, Tsukasa introduces the Guardians a new transfer student in 1st grade, Hikaru. Tsukasa tells the guardians that Hikaru will be a Guardian Apprentice for the time being until the other Guardians graduate. Later, they visit the sports field where Nagihiko tells Hikaru about Basketball. He challenges him to a one-on-one match, full court. Rima states that Hikaru, being a 1st grader, has no chance against Nagihiko, who is a 6th grader.

Amu takes Rikka and Hikaru to an Utau concert and takes them backstage to let them meet her. Rikka becomes embarrassed and tells her when she hears her songs, she feels re-energized. Amu tells Utau that she wishes Ikuto could've come, but Utau tells her that he is traveling the world to find their father. The concert begins, and Rikka discovers one of the X Eggs have followed her. She tells Amu and Hikaru that she forgot something at home and runs off. It turns out that the X Egg loves Utau's songs. Diamond senses an X Egg nearby, and Amu transforms into Amulet Spade. Rikka tries to calm the X Egg down, but Hikaru tells her that she can't help and to just let Amu handle it. Amu uses Prism Music and tells the X Egg to listen to Utau's song. Amu tells the egg that Utau struggled a lot to get where she is now. The X Egg settles and Amu purifies it. They go back to watch the concert, and Utau says that she'll always keep singing no matter what.

Ran, Miki, Su, and Diamond explain to Hikaru that the rabbit is timid and that he needs to gain its trust. He takes the rabbit out for a walk later on, but it runs off and into a patch of flowers; Rikka tries to stop it and nearly falls on them, but Hikaru manages to stop her. The two talk and the rabbit had eaten some flowers that make it ill. Amu's guardians characters suggest some ways to cure the illness, but Rikka yells at them for thinking of ways that can't help it. She lies down and strokes its back, and tells the story of if she was sick, her mom would do the same. The four guardian characters feel bad for Hikaru because his parents had died when he was little.

Hikaru and Rikka are helping Yaya take care of the flower beds. Yaya is working hard to take care of the flowers, along with Hikaru and Rikka. Amu and her guardian characters notice and say it's a little out of character for her. Yaya notices them watching and tells them to come help. Later the next day, Rikka is taking care of the flowers by herself, not knowing Yaya had to stay after class. Suddenly, a X Egg emerges from behind some flowers. Rikka wonders where it came from, but then asks if it wanted to help her out since she was getting lonely. Meanwhile, Yaya is hurrying to the flower beds, with Amu following her. When they arrive, the X Egg has made the flowers huge. Amu and Yaya transform into Amulet Clover and Dear Baby. The X Egg begins doing a trick, trying to surprise them.

Rikka gets distracted from working in the Royal Garden, and goes off to get Yaya and Hikaru at the flower beds. Ran, Miki, Su, Diamond, and KusuKusu were asked to go with her so she doesn't get distracted. Along the way, Rikka finds a bird egg which fell from its nest. She tries to climb up the tree, but fails. The guardian characters than bring the egg back into the bird's nest. Rikka then asks the guardian characters what happens when a X Egg is purified but the owner already has a new heart egg. Ran and the others were unable to answer the question, and soon arrived at the sports field. When they reach the sports field, Rikka spots a X Egg and runs after it. The X Egg is very clumsy and bumps into many things while trying to run away. Ran and the others go back to Amu and Rima telling them about the X Egg. Amu gets to the sports field and purifies the X Egg. Amu then scolds Rikka about going after X Eggs by herself, however, Rikka gets distracted and ignores Amu.

Amu and Rima come across a poster, much to Amu's surprise, announcing an upcoming performance by Nadeshiko just as Nagihiko comes along and is dragged into a predicament. Amu pleas to him that she wants to see Nadeshiko. The three of them go to the stage the performance is going to be held and Amu asks to see Nadeshiko. Nagihiko worries and quickly changes into Nadeshiko, surprising both girls. The charas meet again, KusuKusu almost spilling the beans. After many more wardrobe changes, a Character Change, and Rima's teasing, they all take a walk as Nadeshiko explains that she has missed Amu and always thinks of her. To interrupt this "reunion" a soccer ball is taken over by a X Egg and Amu and Nadeshiko transform into Amulet Heart and Yamato Maihime. Nadeshiko performs a new attack "Robe of Feathers: Dance of the Cherry Blossoms" as Amu uses Open Heart.

Amu and Tadase are on their way home when Yoru sends Amu a picture of Ikuto sleeping, and causes her to blush. When Tadase asks Amu to join him to the park, she tries to hide her nervousness. Ran then Character Changes with Amu to help her express her honesty, and inefficiently catches Rikka's attention. Rikka learns about Character Changing and views Amu's different personality changes: Su turns Amu into a girly maiden, Miki turns her into an artist. Then, they ask Diamond to Character Change with Amu, because they had never seen it before. Diamond fulfills their request and Character Changes with Amu, thus turning her into a sparkling person, much to their disappointment. Later, Amu runs to the park to meet Tadase. Tadase expresses his feelings to Amu. Ran then Character Changes with Amu to make her express her feelings just as Rikka arrives to watch the occasion, but Amu accidentally destroys a sand castle that two kids had made.

Rikka drags Amu to the flower beds, showing her the new buds that have grown. Rima follows them and says that they need to thin out the flowers, because the buds can't absorb sunlight properly if they're too close together. Rikka disagrees, saying all buds should have a chance to become flowers. Amu tries to reason with Rikka, but she misunderstands and runs off. Later on, she finds an X Egg. She starts to say that the egg isn't needed. The X Egg quickly retreats, Rikka running after it. Amu and Rima discover the X Egg and transform into Amulet Heart and Clown Drop. Rikka explains to them that the egg wants to be a baseball player, but is no good at catching the ball. Amu tells the egg that it won't happen if it doesn't try. Amu purifies the egg.

Amu, Ran, Miki, Su, and Diamond overhear Tadase talking to Kukai. He says that there is a girl he that is always on his mind and he can't sleep at night when he thinks over her. He also says that she is really cute. Kukai decides to help Tadase with the girl. Amu is shocked and devastated. Her stubborn character comes out again and at the Royale Garden Kukai stops by and meets Rikka and Hikaru. Hikaru addresses him as the former jack who stops by because he has nothing to do. Kukai defends himself by saying that he gives the Guardian's advice and brings up Tadase's "cute little problem". Amu goes home and consoles herself with food. Amu's Shugo Chara go to Tadase's to investigate and see him, Kukai, and a pretty girl conversing. Kiseki sees them and apologizes that he and Tadase already have a guest before he could finish his line Amu's Shugo Chara yell at him angrily then go home.

Amu and her Guardian Characters all help Rikka out, but Hikaru doesn't understand what all the fuss is about. Hikaru can't comprehend how something as trivial as a gift from someone can be so precious. Amu and her Guardian Characters help Rikka to find it. At the end of the episode Hikaru puts the pen on his pocket, when his grandfather sees it he becomes very happy and Hikaru smiles a little too.

It's finally Sunday, but Amu has a ton of homework to do. However, Amu's mom and dad both have things to do so they leave Amu to tend to Ami, along with household chores. Amu says she has no choice but to do it, and does all the chores. Ami asks Amu to play with her, but Amu says she is busy. Ami goes to Amu's room and starts playing "Cameraman" with Amu's Guardian Characters. Amu tells her to play outside instead and Ami does just that. Ami is at the playground playing with water guns and Amu is watching her. Hikaru finds her and asks what she's doing. Amu tells him and he says he is buying a new eraser.

Finally, when it's over, Hikaru leaves and Amu takes Ami home to feed her. She also gives her a bath. Ami's face gets red from staying in the bath too long, but Amu thinks she is ill.

Amu and the others follow after their Guardian Characters when they sense something strange, and come across a young girl who has lost her heart's egg. The girl is holding a broken stuffed animal in her hand, but they don't know what happened. As they search for the X Egg, Rikka begins to think about who she want to be.

Rikka continues to think about what kind of person she wants to become, but she can't come up with anything. Amu and the gang try to give her suggestions, but she just gets frustrated. Just then, an X Egg appears. As it's the first X Character she's ever seen, Rikka tries to calm it down, but it begins to attacks her. She then runs around saying "Mukatsuku!" (English:How Annoying!) over and over again. Amu tells the X character that it's tough being angry all the time and purifies it. They run to Rikka's aid and she starts to cry, saying that she felt sorry for the X character. Rima wipes up her tears, and says that not all people are strong. Back at home, Rikka says she kind of understands how the X Eggs feel now and playfully try to remove their X's.

Amu sees them and try to stop their fighting but Rikka gets mad and thinks that Amu didnt listen to her. Neither of them have many regrets until they are late for the meeting in Royal Garden. Hikaru comes, Tadase and Naighiko try their best to convince Hikaru that he should apologize to Rikka. Rima and Amu went to find Rikka but couldnt fine her their appears an X Egg, who wanted to have friends but Rikka says she's not going to tell Amu that. However Amu herself talks to the X Egg and Rikka listens and understand that she should apologize to Hikaru too and tells Amu why the egg put an X on it. At the end Rikka and Hikaru apologize to each other, shake hands and make up.

Rikka is excited to have her Guardian egg, and she tries to get it to hatch. However, it does not. She goes to school and tells Yaya, Amu and then Nagihiko, which immediately ends when people realize Nagihiko and Amu together. Later, the Hikaru and the girls are picking up trash. Suddenly, two boys start talking about how the Guardians are there only to pick up trash. Rikka gets upset and ask Amu and Yaya what the use of the Guardians was. She doesn't understand and runs off, only to find an X Egg. Amu purifies it with the help of Miki and Dear Baby. The next morning, Amu and Yaya find Rikka picking up more trash. The same two boys are making fun of the Guardians again, and Amu, Yaya, and Rikka defend the group. Rikka gets the wrong impression from the conversation she had with the other girls the day before, and Yaya has a good feeling that Rikka's egg won't hatch any time soon.

As Hikaru is researching the bar, Amu, Nagihiko, and Rikka comes by and helps Hikaru, telling him to just try and that he might have fun. Mainwhile, a X Egg who is from the volleyball team comes by and starts to attack the 4, telling them that it's never able to play in a game since it's not very good.

Amu is shocked when Utau appears at her house, but Amu's family is very happy to see Utau. The two of them go out to talk. Then, an X Egg, which kept saying 'I don't wanna,' appears. Utau get annoyed and says to it "Why dont you try the thing you don't want to; maybe it turn out to be more greater than you ever thought." Amu says that Utau's right. Just then, Utau realizes that her behaviour in the studio was wrong. Amu purifies the X Egg and Utau says 'Thank You' to Amu, though she didn't know what Utau meant.

Rikka worries about her egg because it didn't hatch yet. She becomes depressed and her egg got a X on it. She wants Amu to purify it but, she thinks Amu will hate her because her egg has a X on it. Then, Amu tells her that she once had a X Egg. Rikka becomes happier and her egg hatches.

Rikka rushes to school and informs Amu that her egg has hatched. Hotaru, who is Rikka's guardian character, gets along with everybody. The Guardians tell her that next year she will become a full-fledged Guardian since she now has a Guardian Character.

Amu and Rikka notice that Hikaru never laughs or shows any facial expression, so Amu decides to take Hikaru out to an amusement park to try and make him laugh.

Rikka is getting closer and closer to Hotaru, and starting to ignore the X Eggs. Amu the other Guardians are getting ready for graduation, and Yaya's sad that she won't be the youngest anymore. Hikaru tells her that she can be the leader from behind the scenes, and still have her baby character.

Rikka starts crying again as Amu gets angry and yells at Rikka, knocking some senses into her. She transformes with Diamond and heads towards the rest of the guardians. Amu uses Twinkle Hold but it failed. Rikka approaches the X Eggs only to have them back away. One egg is close to cracking but Rikka leaps towards the egg, stopping it from breaking. She promises to the other eggs that she would not make them feel lonely anymore.

Ikuto explains to amu that he is back in town to fill out papers to join an orchestra. Amu's mom comes into Amu's room and Amu finds out that Ikuto was there with her permission. He takes Amu out to the amusement park and they ride on the merry go round. Ikuto says he wants to play the "prince character" and then takes it back saying that it's not his character. Amu falls off the horse and Ikuto catches her. Tadase appears, invited by Ikuto. Ikuto parts from Amu and Tadase again, telling her to grow up already. Tadase kisses Amu on the cheek, saying he will always be there for her, leading to calling him "prince".
