Bakako is the elder sister for all the three Chin Irozu brothers. She can materialize ever wherever she want, but on the earth she turn into an owl. Her look is also painful on Chin Chin Irozu planet, and similiar to an owl. She came to the Earth in order to rescue her brother and take them home, but since they refuse to come with her, and she cannot blackmail them to do it -being just an owl- she forced herself to remain on the Kaoru's house. Now she's sleeping in the basement.
