Ulti[4] is one of the Tobiroppo, the six strongest Shinuchi of the Beasts Pirates.[5] She is the elder sister of fellow Tobiroppo Page One.[6]

Due to her actions and role, she is a supporting antagonist in the Wano Country Arc. Ulti is a young woman of relatively tall height,[3] with a light complexion. Her hair reaches near her mid-back and forms rounded locks mainly blue in coloration, but with thin, pink-colored streaks running through (plus a single white one over her left eye). Blunt bangs fall on her forehead, split near the left, and an ahoge stands up on her head. Characteristically (as with many of her crewmates), Ulti has horns: a sharp, upward-curving pair emerging from the sides of her head, white in color, that resemble a bull's. Ulti's eyes are large, round, fringed by long lashes, and encompass violet irises. Her lower face up to the nose is covered by a pink mask with a scalloped edge, trimmed with a white stripe;[5][7] Ulti keeps this mask even when she assumes her pachycephalosaurus form. When in her Human-Beast Form, Ulti's bangs are pushed back, exposing her forehead.[8] Ulti is a bold, rude, and short-tempered young woman, not one to back down from a verbal quarrel and regularly threatening violence against those who annoy her. Somewhat fickle, she is shown acting friendly and trying to come off as refined, mature one moment, then yelling whilst dangerously blunt the next. Not even the likes of Queen or Kaidou, both her direct superiors (and the latter of whom most crew members seem at least somewhat afraid of), are safe from her vitriol, implying that she does not fear them at all, even to her fellow Tobiroppo's shock. Also, Ulti has no issue with generally acting in a highly casual manner towards Kaidou, expressing loud, girly glee during their reunion.[5][7] Ulti is merciless towards enemies and willing to brutalize them without hesitation.[10] She is also not above hitting a child if annoyed, as seen when she clawed at Tama for begging her to stop hurting her friend.[11] In battle, due t
