Kirara Hoshi

The Gachinko Fight Club is an underground fight club run by Kinji Hakari. The place functions almost like a private fighting arena, complete with spectators, organization, and a system for pairing participants.
The venue: It's located in an abandoned multi-story parking garage in Tochigi. The fights take place inside the building, while spectators can watch from designated viewing areas. There are also internal control areas from which Hakari and Kirara can monitor the action.
The fights: the participants primarily engage in hand-to-hand combat and cursed energy techniques. It's not simply a no-holds-barred street fight: there's an organization behind the fights, and Hakari decides who participates and how they unfold.
Betting: a key part of the club is that spectators can bet on the fights. The money and the spectacle are one of the reasons the club is able to continue operating clandestinely.
The most important rule: the fights are organized for entertainment. The participants aren't there simply to kill each other. Hakari seeks fighters capable of providing interesting matchups and keeping the show going.
Security: The club has staff responsible for monitoring the premises and controlling who enters. Not just anyone can show up and freely access the facilities. That's why, when Megumi, Panda, and Yuji arrive, they need to enter quite discreetly.
Hakari as administrator: He's at the top of the club's structure. He not only fights, but also organizes and oversees the matches. Kirara acts as his right-hand woman and helps control the facilities and who enters.
And importantly: for Hakari, the club represents his idea of ​​"passion." He believes that people can find something that makes them feel truly alive and become obsessed with it.

Kirara Hoshi used to be a man, but from the age of 15 she began her transition, consuming all kinds of supplements and undergoing operations.

Her closest relationship is with Kinji Hakari. There is an extremely strong bond of trust and loyalty between them, and Kirara stays by his side even when they are away from school. She enjoys seeing him passionate and considers it important to keep that intensity alive, which they both call "passion." She also tends to get jealous or uncomfortable when Hakari's attention shifts to other people, although the series doesn't officially establish a romantic relationship between them.

She's involved with the fight club Hakari runs, where sorcerers fight each other illegally. She's Hakari's right-hand woman and helps run it. She earns some money from it.

Her personality is expressive, affectionate, distrustful, and quite protective. She has a cheerful and energetic attitude, but can become immediately serious when she feels someone poses a threat to those she considers important. She is very observant and possesses considerable tactical intelligence, especially when using her technique. She doesn't easily trust witchcraft authorities and maintains a rather critical stance toward the traditional structure of the school.

Her cursed technique is called Love Rendezvous. It's an extremely complex, innate technique based on the five main stars of the Southern Cross constellation. Kirara can mark people, objects, and other sources of cursed energy with five different stars: Imai, Acrux, Mimosa, Ginan, and Gacrux. Each mark establishes specific rules about how they can approach one another.
The fundamental rule is that the marks must follow a specific order to be able to close the distance. If a target tries to deviate from that order, the technique prevents them from closing the distance correctly. Furthermore, two targets with the same star can attract each other. Kirara uses these rules to control her enemies' movement, block paths, protect certain areas, and draw objects toward specific targets.
This makes Love Rendezvous much more of a battlefield control technique than a skill intended to directly inflict damage. Kirara can prepare objects in the environment in advance and turn them into obstacles or projectiles, while using the rules of the stars to limit the available routes. Its true danger lies in the fact that the enemy needs to understand how the technique works before they can counter it effectively.

Her outfit consists of a light-colored, off-the-shoulder, red-strap crop top, paired with a studded choker. She wears loose black pants held up by red belts and dark heeled boots with red socks. She also wears several bracelets and accessories, reinforcing her extravagant and carefully curated style.

Kirara Hoshi is slender and distinctly feminine, with a slightly voluptuous figure. She has long, black hair that falls just below her shoulders, with straight bangs and two face-framing strands. One of the front strands is dyed cyan. Her eyes are large and purple, with star-shaped pupils, and she wears four circular piercings around her mouth and chin. Her aesthetic is heavily influenced by gyaru style, combining striking elements with rather bold accessories.
