Previous trailer: Fuyuki was about to go to the principal's room to talk about the club's activities at the school. Not forgetting he brought important documents containing club information that had been closely arranged at yesterday's student council meeting. Then Ran found an oddity in one of the clubs where it was called a happy club. Fuyuki tries to meet Kei. In addition there was a gloomy girl in her class who also wanted to submit a request to set up a club of the same name.
Can Fuyuki do it?
Meanwhile, Mawaru had wanted to talk one-on-one about his mission in the Mansion.
At recess, Fuyuki invites Mawaru to the headmaster's room, with him.
When they entered, and sat down then opened the bento, shortly afterwards the door of the room was locked. Kei wasn't there either.
