Quelou

A half-werewolf slave. Though capable of following orders, she frequently falls into anxiety and panic, hence her low price.

Timid by nature, she works nervously and anxiously, causing mistakes at things she could otherwise accomplish.

Captured by slave hunters, she was sold to a slave owner and subjected to one-sided abuse. Even though Quelou expressed her willingness to obey by begging for mercy, she was still subjected to senseless cruelty.

However, the slave owner's own terrible eating habits led to sudden death, and Quelou was sold off to the slave market as part of the estate liquidation.

Though she changed owners, the painful memories of those days made Quelou constantly fear being locked up again. She would frequently fall into severe panic attacks, rendering her completely unable to function.

As a slave, Quelou's mental state had deteriorated to the point where she could no longer properly follow orders, making her a cheaply sold commodity.
