Kuin Hachisuka (蜂須賀 九印 Hachisuka Kuin?) was a student and part-time villain serving the Villain Factory in the spin-off Vigilante - My Hero Academia: Illegals. With her Queen Bee Quirk, she possessed Tamao Oguro, the daughter of Knuckleduster.
Kuin was a young girl with short brown hair, styled so that it’s swept over her left eye, with two short ahoges sticking up at the end of her parting. She has green eyes with notably long eyelashes, and visibly sharp teeth.
She wears her school uniform, which consists of a white dress shirt with a bow at the neck, a short pale skirt and a dark jacket with white sleeves which she adds over the top. She also wears dark nail polish, and normally wears an eyepatch over her left eye because of the damage Stendhal's attack did to her.
Kuin appears to be a cheerful girl who is described as strange by her own friends.
This cheerful attitude is, however, nothing more than a farce. In reality, she is a ruthless villain who does not seem to care about the destruction caused by the victims of her bees. She is also extremely manipulative and enjoys toying with the emotions of her potential victims.
She seems to be very fond of her bees, which she calls her "babies."
By utilizing Trigger, she sacrifices some control over her host body in order to achieve more strength, giving Tamao Oguro back some control.
Queen Bee (女王蜂 Joōbachi?): : Kuin's Quirk allows her to call and command worker bees which can attack and sting people. Kuin can enhance her bees' stingers by attaching items to them such as Trigger. Kuin's Quirk gives her a wide range of attacks, as she was able to use her plethora of bees to inject Trigger into dozens of people simultaneously. When her bees are killed, the damage is reflected in her body, as shown when Knuckleduster crushed one of her worker bees and Kuin's eye started bleeding and she felt pain.
Eel (ウナギ Unagi?): After injected herself with a blood sample collected from the Next-Level Villain Teruo Unagisawa, Kuin was able to use Eel as a second Quirk, being able to emit electricity from her fingers.
- Bomb Bee: Using the Queen Bee Quirk, Kuin can create Bomb Bees, highly explosive bees that detonate when ordered to. Creating even a single Bomb Bee takes a toll on the host, and as such the ones created after the first are simple firecrackers.
