バニラ

Vanilla is the innocent but scatterbrained and ditsy heroine. She tends to say things that seriously lack self-awareness, so the others will simply ignore her. Although she seems to be uninterested in what's going on, she actually has a very sharp mind. She is very quick to catch on to adult conspiracies. [From official site] Initially believed to be the ghost of Vanilla, who passed away before the start of the game, she is the mastermind behind the Game of Fate, a fake Death Game created to break the brainwashing controlling her friends. Is revealed to be alive but comatose, using her ability of astral projection to appear to her friends as a spirit.
