A bit late, but Zaizen got some gifts for people.

Kenya: A song, written, composed, and sung by him. Very touching stuff.

Marui: A song written and composed by him about Marui being cool, with a note saying he'd have sung the song himself if he'd realized he'd end up liking him so much and that he'll sing the next one for him.

Tachibana: Superhero chef song.

Kintarou: A song about space hero Tooyama being awesome.

Gakuto: Lyrics to an unfinished song about his adorable relationship with Hiyoshi. Lol.

Akutsu: Lyrics about being too cool for a lame song. Also a note thanking him for breaking Marui's heart so he had a chance with the guy.
