This is a large crossover, so spoilers for: Persona 4, Fate/Zero, Kara no Kyoukai, Neon Genesis Evangelion, and Tsukihime.

Because of some lazy ROB, now I am in the Moonlit world. Reincarnated as Shinji Matou was another slap in the face. At least I have the power of my favorite video game, Persona 3.
