Kayoko Onikata

The "Section chief" of Problem Solver 68 and a 3rd year student at Gehenna Academy.

Unlike the other fixers, Kayoko is not one with ill intentions. However, she is often misunderstood as a delinquent simply due to natural scary facial expressions and appearance. She normally prefers to keep silent about this topic, as it likely leads to furthering her terrifying image.
