My reasoning is based in the events of the game
i know almost perfectly what happened in n0 up to 2
Here:
N0: i attacked nano, chiaki, who transformed, mafia attacked Kiet
N1: I attacked amethyst, who was immune, lykos was attacked by mafia
N2: i killed cass, a blackened, while the mafia targeted Yahen, Hajime
There's no way that nano lied, since im telling the truth and the real chiaki wouldn't be killed at all if she wasnt nano
