Toru is a bubbly, cheery, and easygoing girl that does most things with an upbeat attitude, even if manipulated to do so. She is very socially eager, and appears to like shopping. Her room suggests that she likes plushies and other cute things.

She believes that taking off her clothes during battle is a tactical advantage, much to the awkwardness of those around her. That being said, she seems blissfully unaware of what it means to be invisible, such as displaying slight embarrassment at the idea of being watched undressing; a trait that shows up even when she's wearing her Hero costume, which features almost no clothing in the first place.

In general, it appears Toru's invisible body is primarily used as a source of comic relief.
