Note: Updates will come whenever I can, because my equipment is garbage.
I haven't settled on the protagonist's name yet, so for now let's call him Zhang San.
Zhang San died suddenly in his original world, but by a twist of fate, he transmigrated to the world of Girls' Frontline and obtained Obito's Six Paths template. (Note: He'll level up gradually from scratch to the Six Paths stage, so he isn't an overpowered protagonist.) How could he not take off from there?
He founds an organization and becomes the biggest headache for the three major organizations in the main story.
Zhang San's path above the ruins.
