Tsukino's mother was a very skilled baker who had the potential to raise to become the master of the main branch of Pantasia that she was working at. She met Sadamichi and together they had Tsukino. But he was already married and had an older daughter Yukino with his wife.
Tsukino and her mother were very close.
She died of unknown causes at one point. Sadamichi's legitimate children (he had another daughter with his wife giving Yukino a younger sister, who is Tsukino's half-sister) call Tsukino's mother a "thieving cat" and despise her for her mother breaking up their marriage and stealing attention away from them.
