Tira is a character in the Soul series of fighting games, a loyal servant of the evil Soul Edge. Tira is referred to as the "The Misguided Angel of Death" during her debut appearance in the official E3 teaser for Soulcalibur III. She made her first appearance in Soulcalibur III and appeared in the next installment, Soulcalibur IV. In Soulcalibur IV she undergoes a drastic evolution in design, exchanging the teal-colored hair, green rags, and feathered fringe she wore in Soulcalibur III for dark brown pigtails and a red ensemble. At first this dramatic change was speculated to be the outcome of one of Tira's epilogues in her Tales of Souls in Soulcalibur III, in which she was possessed by Soul Edge, but the real reason was to reflect her unstable new personality, as revealed in an interview with one of the character designers of Soulcalibur IV. She has also returned in the new videogame Soulcalibur: Broken Destiny.
Tira fights with a unique type of weapon reminiscent of a bladed hula hoop, appropriately called a ring blade, which she can effortlessly swing using her wrists, feet, and body. Her battle style relies on acrobatics, speed, and flexibility.
