多达100万柄的圣剑Excalibur——其强大的力量扭曲了历史，为了破坏这100万柄圣剑，团长·铁拳·阁下·炼金·山猫·流浪——6位亚瑟前往过去的不列颠。可是，作为领导的团长奇妙的行动让其他人感到困惑，队伍迅速面临崩坏的危机。就在这时，此地的亚瑟们察觉到了团长他们的行动，反而集结起来要讨伐他们。聚集的人数约有1万之多——！

喜欢历史又勤勉认真的炼金亚瑟，对胡闹的团长他们感到了无望。加上被其他人当成小孩子对待，更积累起了不满。收到了新的圣剑情报的她，丢下大家一个人出动了。发现到这一点的团长慌忙追了上去、和炼金亚瑟争论了起来。这时，一个可疑的男子出现了——

为了破坏圣剑Excalibur，铁拳亚瑟和阁下亚瑟来到了矿山边的小镇，阴差阳错地成了矿工。如果说阁下亚瑟还有些不情不愿的话，铁拳那可是适应得很。这样的两人遇到了广受矿工们信赖的矿山社长，确实是个令人尊敬的人。然而，阁下亚瑟在矿山的矿石中发现了疑点，调查开始了。

看上去认真严谨、和团长正好相反的山猫亚瑟，在听说某地似乎有圣剑Excalibur时、罕见地率自出动。和她一起行动的是流浪亚瑟。到达那儿以后，明明就快到收获祭，可不知为何到处是一片悠闲的风光。正在调查时，流浪亚瑟感到了杀气。另一边，山猫亚瑟来到了她的“圣地”。

循着圣剑Excalibur的线索，阁下和团长到达的目标……居然是女校！阁下再怎么嫌弃，还是被迫穿上女装，二人开始了潜入搜查。可团长与其说是在搜查，不如说是享受起了女校的生活。纳克拉维和碧姬也换上制服，完全变成了女高中生。女装阁下还被美术部的女生拜托当模特，这个美术部一定哪里有问题

想要一次短暂的歇息，以团长为首的女性亚瑟和妖精们到了某个度假设施，将任务完全抛在脑后，换上泳装开始美美地享受假期。然而事件还是发生了——围绕身着泳装的女孩子们，发生的事件当然就是“那个”了！这次要对付的亚瑟，他的圣剑Excalibur能力可不简单。

掉落悬崖、被激流冲走的流浪亚瑟，被一名女性救起。她住在蔷薇盛开的别墅中，作为当地的领主受到民众们的仰慕。而追求着她的贵族公爵一看就不像好人。被卷入的流浪怀疑公爵也是需要打倒的“亚瑟”之一。

为了破坏圣剑，炼金、山猫、阁下来到某个海边小镇。这里在未来将是有名的遗迹，炼金为此兴奋不已。可实地到访之后，竟和后世历史中记载的不太一样！？此时出现的，是仿佛从哪部动画里出来的3名魔法少女，她们自称就是守护这个小镇的亚瑟。

明月照耀的夜晚，在铁拳亚瑟他们面前，一名可爱的少女从天而降——是传说中的偶像·辉夜。像高傲的公主一般的辉夜，正为恶心的粉丝所困扰，要求铁拳他们成为自己的保镖，开始了不情不愿的同行。铁拳对辉夜的魅力完全不为所动，辉夜感到自尊受到了伤害，誓要让铁拳尝到报复的滋味……

团长他们今天也在顺利地完成任务中。亚瑟们结成的骑士团被瞬间击破……其中的占卜亚瑟还做出了“有更为强大的阴影逼近”的预言。难道团长那边还会增加新的战力？战栗不已的亚瑟们，终于决定实行一个惊人的作战。了解到这一切的团长他们，面临迎战、还是逃跑的选择。6人的答案是——

After their encounter with Pharsalia, the team abandons ship. Now it's up to their one-and-only leader to corral the crew and complete their mission.

Since Dancho won't take things seriously, Rurou and Kakka go off on their own. But she'll do whatever it takes to earn their trust and will fight to get them back.

The team looks far and wide to find Yamaneko, but she's already become a changed person. Dancho is forced to say goodbye to the Yama she loves so dearly.

Like Yamaneko found out, not all hot springs are equal. But that doesn't stop everyone else from taking a dip and creating problems of their own.

When a gourmet destination turns out to be a dump, Dancho and crew put their cooking skills to the test in a cuisine showdown versus one snobby chef.

Imagine Yamaneko's delight when Utahime stops by for a visit. But as Yamaneko founds out, there's more to her favorite idol than meets the eye.

Dancho and the others are forced to the field for a game of soccer. Can they somehow manage to work together and defeat the best team in Britain?

A city is at war due to opposing views. Kakka seems determined to do the right thing, even if it means abandoning both team and mission.

After all that happened, Kakka is in a hurry to prove himself. But when things go amiss and someone gets hurt, he digs deep for power within.

Despite all her research, Renkin isn't the first to successfully Fairy Combine. But when she storms off to hit the books again, she is swiftly wooed by a persuasive prince.

The stakes are raised when an Excalibur is detected in Britain's largest casino city. But they aren't having much luck finding it until Bethor goes all-in.

Desperate to Fairy Combine, Dancho lands herself in a pinch with Tekken. What's more, a dreadful enemy threatens to destroy everyone on the spot.

The team must look deep within to answer the big decision ahead of them. Will Dancho and the team flee to the future or fight Pharsalia and unite as one?
