Mosquito
モスキート
Mosquito is Arachne’s butler. His appearance is a short old man with a large pointy nose which is used to suck the blood out of a victim. He has mentioned that he can transform into his form from 800 years ago which could mean he is stronger then he lets on (but it seems he needs some high grade blood to pull the transformation off). He has a sense of honor since he let Maka, Black Star, and Kid leave during their fight since their (Maka, Black Star, and Kid) time was running out and they impressed him during the fight.
