Kayoko
Kayoko is the department head of Problem Solver 68 at Gehenna Academy. Despite her intimidating appearance, she holds no ill will toward anyone and is often misunderstood as a delinquent. She has white hair with black bangs and a black ponytail tied to her horns, red eyes, pale skin, and a mole in her lower neck. Kayoko wears a black hoodie with the service logo 'Born.To.Kill' on it, along with a standard uniform underneath, including a brown t-shirt, pleated plaid red skirt, and black sneakers with red lines. She uses a two-tone Heckler & Koch P30 pistol with a black suppressor. As part of Problem Solver 68, Kayoko is involved in 'illegal businesses' and takes 'fixer contracts', often finding herself on the run from the Prefect Team and the Justice Task Force. Despite her tough exterior, she seems to have a softer side that she doesn't reveal easily.
