Kirara Hoshi

Slim and youthful, Kirara carries a notably feminine look. Their black hair falls to just behind the neck, with a flat-cut fringe shading the forehead and two trimmed strands hanging at the cheeks; the right portion of those bangs is colored cyan, while the back is wispy and sticks out in scattered directions. Four circular piercings ring the lower mouth, two flanking each side, one beneath the lip, and one set into the chin.

The eyes are large and purple with yellow pupils shaped like stars, paired with thin brows and prominent lashes. Kirara dresses in a pale off-shoulder crop top fitted with black straps, a spiked choker, baggy black trousers cinched by two white belts, and dark heeled boots.

Above all, Kirara is defined by devotion to Hakari, whom they affectionately call "Kin." The pair share a belief in the "fever," and Kirara delights in seeing his run hot, growing visibly cheerful whenever it returns. That attachment can turn possessive: Kirara discouraged Hakari from investing attention in Yuji during a phone call, pushed back against planning the newcomer's fighting future, and bristled at any mention of his ex-girlfriend. Fond of handing out nicknames, Kirara dubbed Yuji "Yu" almost immediately.

Their protectiveness fuels a deep distrust of Jujutsu High and its conservative leadership, whom Kirara blames for relying on Satoru Gojo to fix every disaster. When Megumi and Panda were caught prowling around the fight club, Kirara instantly read them as agents of the school and felt betrayed by Panda especially. Even after the two clarified they only wanted help, Kirara stayed skeptical, greeting the news of Gojo's sealing with open disbelief. Once Megumi sincerely pleaded to be heard, however, Kirara relented and even helped persuade Hakari, recognizing the fever burning in Yuji and pointing it out so Hakari could no longer deny it.

Three years of study at Jujutsu High gave Kirara a sophisticated grasp of jujutsu and a complex innate technique they have thoroughly mastered, making them a genuine asset to one of the school's strongest sorcerers. Kirara sealed off the fight club's monitor room so effectively that no one, Panda included, could reach Hakari uninvited. Outnumbered two to one by Panda and Megumi, Kirara pre-charged rooftop objects with cursed energy and used them to keep both attackers at bay, immobilizing Panda and forcing Megumi into a risky gamble. Kirara also assisted Ui Ui in pulling injured allies clear during the raid on Sukuna in Makyo Shinjuku.

As a thinker, Kirara matches Megumi blow for blow. They tracked his attempts to deduce the rules of their technique, noting when his Rabbit Escape risked drawing the swarm back on himself, and went on the offensive the moment he grasped the basics. Their cursed technique, Love Rendezvous, assigns five "stars" patterned after the Southern Cross to mark cursed energy; a target carrying one star can only approach another by following a fixed order, while shared stars attract one another. The sequence runs from nearest to farthest from Earth: Imai, Acrux, Mimosa, Ginan, and Gacrux. When Megumi believed himself safe from incoming objects, Kirara stripped their own mark and re-marked a projectile to match his, pelting him with debris.
