They escaped.
All fifteen of them survived the game of despair at Hope's Peak Academy, without losing a single person. That is what happened in the IF timeline.
But being alive has never been the end.
Makoto Naegi and his companions stand before an abandoned mansion. The remnants of despair have infiltrated the Future Foundation, and they can no longer trust anyone. So they make a choice:
They will join no organization and rely on no faction. The fifteen of them will start from scratch.
The fifteen work together, each taking on a role. Every talent that seems “useless” becomes the key to turning the tide at a crucial moment. One by one, they hunt down the scattered “Remnants of Despair” from Class 77, without persuasion or hesitation, working together with ever-greater coordination.
And in the process, the bonds they had “forgotten” at the academy begin to slowly form anew.
It's been a long time since I've read a bullet article, so I'll leave a comment to support it.
It's good, but in the part where you get a mobile phone and find contacts, I suspect the author doesn't know much about the characters at all.
Support support! The author must be more thorough! 💕💕💕
