The substantial protagonist of the manga, who has long red hair. She behaves like Edokko and speaks in a masculine tone of Edo speech, but she is actually from Tokushima Prefecture. Despite her good looks, the way she talks and her flat chest tend to lead the others into suspecting her as a boy cross-dressing as a girl. She acts tsukkomi and often says "Don't ask a trifling question! (つまんねー事聞くなよ！ Tsuman'nē koto kiku na yo!?)". Her name is a pun on Bloody Mary.
