Tomoe is a fairly relaxed person, who never says anything bad about other people or holds grudges against them. She keeps the band from falling apart and is idolized for her cool, but mature way of handling things. Despite her mature, punk look, she is very caring towards others and is always there to lend support or a shoulder to cry on. While she is unable to understand Ako's behavior at times, she loves her sister and supports her no matter what.
