I'm looking for a manga! It's about a little witch girl that was looking for the dark lord. She confuses a retired knight to be the dark lord and so she begs him to let her be his disciple/slave. The personality of the 'dark lord' is somewhat of a clean freak. The fist time they met was when the little girl crashed into his house. OHHH they also had a pet dragon

It was about a group of girls who stole money from guts who wanted sex. Their rule was not to sleep or fall in love with them. The MC meets an artist and he hires her to be his nude model. The artist had a cousin who looked like a girl btw. Anyway, the MC starts to fall in love with the artist and later she finds out that the only reason the guy hired her was because she looked like his dead girlfriend.
I wish they would've played dodgeball :u
