Tsubaki debuted in Season 4. She sees herself as the perfect lady, and is boastful about her perfection that existed since she was born. She originally was envious of Akari, questioning why she was able to get a Premium Rare Dress from her favorite brand Dreamy Crown while she was unable to get one. The two later become friends as Akari helps Tsubaki. Tsubaki then realises that Akari is what she aspires to be and admires her hard work. She calls Akari a "Perfect Idol." (Source: Aikatsu! Wikia)
