Named for the Italian dessert (tiramisu), Tira is the younger of the two Misu sisters. She and her elder sister Chocolate were raised from childhood by Onion and Apricot Glace, the parents of Carrot and Marron Glace. In their childhood both Chocolate and Tira fell in love with Carrot, and they both carry these feelings to adulthood.
In the end of the manga, Tira marries Carrot.
Usually shy and sweet, when Tira gets ticked off-- in battle or because of Carrot flirting with other girls --she throws off her cloak to show off her more revealing outfit and whips her enemies (or Carrot) into submission. Although it may seem like mere jealousy with Carrot, Tira's whippings are the only thing that can revert Carrot back to humanity if he gets stuck in his monster form.
Tira usually has a "little red riding hood" appearance, wearing glasses and a large red cloak.
In the manga and OVA, Tira wears a classic dominatrix outfit: black bustier, fishnets, chains, stiletto boots, and a whip (or occasionally a wire instead).
In the TV series, TIra's dominatrix outfit is swapped out for an orange and white leotard.
