Identify Dude with Purple Demon?

[withacomb]

MC goes around with purple succubus/demon looking for people who are corrupted or something and he lives with his stepmother and stepsister. There's also a school setting with one of the characters who had his bike set on fire.

There's a Facebook parody in it too called Fuckbook I believe.

A purple succubus makes me think of Depraved Town, but probably this isn't the game you're looking for.
