Tsubaki is said to be unpredictable, and her speeches usually carries profound (hidden) meanings. She uses abusive language a lot, but said that it's how she shows her love. She loves freedom and hate to be restricted, so she doesn't like doing group activities. She prefers to watch over her members, all while putting up an elegant, yet meaningful smile on her mien. She refuses to be called as denpa-kei (a fantasist, abruptly says non-sensible things as if getting possessed) and proclaims herself to be categorized as fushigi-kei (has peculiar taste in things, mysterious, and do things that are hard to understand).
