Mimi

Mimi and Sheshe are lovers. Mimi is the younger sister of Sheshe. Together, the two of them are known as the Black Beauty Sisters. There has been a common misconception among fans that Sheshe and Mimi were lovers in the manga and were censored to be sisters in the anime, when in fact, they still referred to themselves as sisters even in the manga. The sisters exhibit behavior reminiscent of lovers, however the precise nature of their relationship was left unstated within show canon. Later interviews with cast members suggest that their relationship is indeed romantic.
