Huh... I wonder what Tooru meant by "Well... Sort of...", when being asked if she was a girl.
Het Twist incoming! xD
sry, couldn't stop myself
It's probably something simple, like dragons don't care about boy or girl. They are dragon. The transformation spell just turns them into what human form fits them best. So before her transformation, tooru wasn't living as a girl dragon, but just as a dragon.
If that makes sense xD
