Lol this is so stupid. Terasawa has just tried to have Toki tied up and probably killed later. His lies have been exposed , everyone has rejected gooing along with his plan to tie up toki, now is literally the perfect time to tell everyone what actually happened.
If you let terasawa get away then he'll just have more time to prepare another attempt to kill you . That was the perfect time to ruin terasawa's reputation and then when everyone knows that he's a rapist and that he was commanding the murderer matsuda, everyone will be afraid of him and he can be socially boycotted. terasawa can't beat up 8 men and 8 women himself. literally the best opportunity to do something about it while everyone is there and they've just expressed their support for Toki
