Chinatsu Morikawa is one of the main protagonists in Lostorage incited WIXOSS and Lostorage conflated WIXOSS. She is a very serious girl who hates losing above all else. She can be selfish and stubborn due to her habit of making decisions that end up causing more trouble for the people around her e.g. ignoring her parents' financial troubles because she wants to stay in her private school. She later snaps after losing twice in the Selector Battles and because of the rumours circling about her; she takes on a much colder personality later after winning her first battle.
