Wrench Luncheon

She was the daughter of Ratchet Luncheon, the previous owner of the store, and she inherited it after he was killed by Rance and Kentou Kanami. Her father was very possessive with her, to the point of making her feel very uncomfortable about it and she claimed to have experienced sexual harassment from him. At some point prior to Rance 03, she lost her virginity to Rance after being raped by him, which instantly turned him into a despised enemy of her father. After his father knowingly fooled Rance and deliberately sold the Holy Armaments from Leazas he was desperately needing at the time, Kanami killed him off for good, leading Wrench to become the owner of the store some time after as a result.

Initially unbeknownst to Rance, she suffers of a rare dissociative identity disorder, alternating between two completely opposite personalities. One is a timid, weak minded and submissive girl, while the other shows a hussy, assertive and aggresive demeanor. What causes her personality to change is unclear but it seems to alternate every day.
