Ghost Hunt

Takigawa-kun (Bou-san/the Monk) and Mai, from Ghost Hunt. It's a good show/comic despite not having an ending.
(apparently the ending will be a radio drama because that is how much money and resources they do not have, or because someone is being a lazy arse and not drawing the rest. dunno the details, but for an english speaker, radio drama is almost impossible to find a good translation of so I am super pissed off)

There is a dumb line on his face. It shouldn't be that close to his mouth.

FLOATING SKULLS!
