Cacao (formerly Sugarcane, the name given by Azuki) is a stray cat found by Chocola when she went out to buy ponzu for tuna. Cacao followed Chocola until she arrived home. The Minaduki thought that this is a lost cat and they tried to find an owner for it but they couldn't find one. Now Cacao lives with Chocola and Vanilla in Kashou Minaduki's house because of Chocola's wish for her to stay there. "Cacao" is a name chosen by Shigure Minaduki and the Minaduki cat-girls later on.
