I actually found the ghost of Takahashi's Explanation more than scary than the ear-slashing Monk. The Ear-Slashing Monk was horrible but you knew what he was up to and after that he left them alone (presumably). Takahashi's ghost you don't why or how and even though she seems to know he's the wrong person SHE'S STILL FOLLOWING HIM. I always end up attributing nasty reasons to ghosts like that. Like the one in the grate.
