(Game Crossover) A Teacher's Career

Blurb (provisional): Three doors lay everything he has experienced before him. Some things are taboo, but even if punishment is the price, they still have to be done... The price of bringing three people back to life is... witnessing three worlds collapse and be reborn. (World Three) Makoto Naegi: Junko, the person I like is Mukuro Ikusaba! If you keep despairing, I'll get a teacher to set you straight! Nagito Komaeda: Ah~ As expected of a teacher... [Someone covers his mouth] Hajime Hinata: Sorry, I'll make sure to talk to him properly. Teacher. (World Two) Fuuka Yamagishi: Even if you and Kanade-senpai aren't here, Teacher, I'll stay strong and keep living! I'll start by making friends... Rise Kujikawa: If Yu Narukami-senpai is the person I like, then you, Teacher, are the person I respect most. So I still want to keep being an idol! (World One) Hibiki Kuze: I love you... my [Eternity]. So take me with you... He? Runya: I really shouldn't have taught you to get to know your other self in the first place.
