Lenny is a Rat appears in the same Chapter, Episode 1. She acts as the "surgeon" while gut-harvesting. She belongs to a group of Rats that is composed by her, Pete, and Mang-chi. (Rats are essentially ghetto dwellers, willing to do any job or criminal act in order to get by.)

Lenny seems to be the calmest of the Rat trio. Unafraid to shove her hands inside of living people and removing their guts with the cleanest cut possible. Other than being calm she is also very time-aware, paying immediate attention to the fact they only have 7 hours to pay a debt.

Lenny has more of a lighter voice, and tends to be rather expressive.
