Ash

Ash is in the same gang with Grom. Their surroundings are the "Castle Courtyard".
Ash is Scottish, which is why he has such a rude accent.
Ash becomes enraged both because of the garbage he has to clean up, and by striking and receiving blows. Rage makes him faster and more dangerous, but he cools down over time.
Ash attacks, slamming the broom down with force. Get out of the way, or you'll swallow dust!
He is constantly nervous and angry, he hates his job
He also keeps a mop with him at all times
