Also known as: 丸井みつば
Series: Mitsudomoe (Manga)
Also called: Micchan, Choujo ("oldest daughter")
One of the three main characters, the Marui triplets. Mitsuba is the oldest by a matter of minutes; you'd think that wouldn't mean much, but it's gone straight to her head. She's haughty, sadistic, and nasty, a Tsundere with almost no dere. She has the requisite Twintails and is only interested in the opposite sex when there's Netorare potential.
