Heather is the leader of the antagonist trio of magical girls in the tabletop RPG I had to put on hiatus.

She has a huge crush on her senpai in kendo club, though she swears up and down that it's just a healthy rivalry, really.

Said senpai is one of the magical girl PCs who Heather is convinced is one of the bad guys, like a bomb with a lit fuse. Heather isn't aware of senpai's secret identity.
