Ayumu finds himself wearied by the stress of everyday life, and happens upon a drinking partner with whom he is able to share his concerns. Meanwhile, Haruna's increased appetite has her thinking she has recovered her Magical Garment Girl abilities.

With Mystletainn unable to erase anyone's memories, they still remember the events of the day before, thrusting unwelcome attention upon Ayumu. Tomonori invites Ayumu to go up into the mountains, to get away from the commotion and do some stargazing.

Haruna and Eu perform a delicate operation on Mysteltainn to try to repair the damage done to him. Ayumu gets advice on how to deal with Orito. Tomonori takes a crash course in dancing in order to be a backup dancer for Sarasvati at her upcoming concert.

Thinking he is doing him a favor, Orito invites Ayumu out to a restaurant run by the vampire ninjas, which offers a full course of unsociable service. Afterward, the two of them engage the ninjas in a mood-changing contest, to win the cost of their meal.

Sera and the other vampire ninjas are called back to their village, leaving Haruna in charge of the house. Eucliwood comes down with a fever, and Ayumu goes to great lengths to look after her, but ends up having to call in outside, underworlder help.

The Head Teacher calls Ayumu with news that Mystletainn will be returning shortly. Souyu High School holds its culture festival, and Haruna helps Ayumu's class prepare for their activities. Ayumu admits to a sense of fulfillment in his high school life.

Having absorbed Eu's magic power, Haruna now suffers from the same side-effects that prevented Eu from speaking. The culture festival enters its second day. Tomonori has her control ring taken from her by the teacher, leading to an unforeseen outcome.

Kyoko returns, offering to reveal Chris's weakness, but only if Ayumu will keep her sufficiently entertained. She wants him to throw her a big blind-date party, with lots of people. Will getting all of the arrangements made be too much for Ayumu?

In order to defeat Chris and get Haruna's magical power back, Ayumu meets with Nene, the mightiest of underworlders. In exchange for her help, Ayumu and the others help her illustrate her comic. Meanwhile, Saras gets ready to put on another concert.
