Welcome to the Phantom Thieves
You decide to leave the app alone and head home. Once you get back to your home, you tell your mom that you had a great day and sit on your bed. You take some Advil and eat your dinner, then fall asleep. The next few days, everything is normal until you have a morning assembly when they start to talk about suicide prevention where the P.E. teacher and volleyball coach, Kamoshida, runs onto the stage and starts to confess out of his mouth of all of the horrible stuff he did to the students while he was teaching at Shujin Academy. You remember about seeing a calling card from the Phantom Thieves saying that they would steal his heart and he was going to confess his sins if he wanted to or not. As you remember, the principal ushers everyone to get back to their classrooms and you start to believe that the Phantom Thieves might be a real group that can make people confess their crimes. School goes back to normal with little murmurs of Kamoshida being spread throughout the year.
