After another loss at the hands of the Three Mermaid Princesses, the Black Beauty Sisters bicker at each other because of Fuku's comments. Mimi leaves Sheshe during their argument because Sheshe keeps on blaming their losses on her. Mimi meets and befriends Lucia, Hanon and Rina not knowing their identities. She tries to capture the mermaid princesses on her own, and fails, almost dying. Sheshe uses the new power given to them by Michel to heal Mimi, as she doesn't care if they get "kicked out" or not; she would rather die in the sea with her sister.
