Happy Seven: The TV Manga

Synopsis

Amano's friends are reporting the club, as part of a ruse put on by Tomoya to discover more about the club, while at the same time the club is following a girl whom they believed to be possessed; however, Kokuanten, now recovered from the last battle, find her first, creating a plan. The girl eventually makes her way to the club, and tells them that she no longer believes in anything anymore. They take her to the prayer stone, but she is unable to believe it will work. Amano prays with her, and beings to glow, freeing the girl from the monster. The monster attempts to attack the group before any of them are able to transform, while Amano's friends, whom had been left behind, discover the group and are about to hit by a blast from the monster, while Amano attempts to push them away, all three getting hit. Before they land a large light shines from Amano, causing the three to transform into the "Lucky Three", leaving the Seven, whom were yet to transform dumbfounded. The three quickly destroy the monster, before changing back. Amano's friends then pass her the notebook they had been writing, with information all about Kikusnosuke, hoping it can help her win up the courage to tell him her feelings. Thereafter Kikusnosuke wipes their memories; while Tomoya gets the information he wanted.
