Kaitabi Hatsuya

Hatsuya is a Level 2 Power User who was on the receiving end of a lot of bullying. He became hateful towards Judgment for always showing up late or not at all. When he obtains the Level Upper to enhance his ability, he starts to attack various Judgment members as revenge. His last attack was on Kazari, but she was protected thanks to Tōma's Imagine Breaker, and Hatsuya is subsequently beaten by Mikoto.

His power is called "Graviton" by Judgment. His ability allows him to use aluminum objects as explosive devices through extreme compression and a subsequent release of energy. The Level Upper version of this ability (categorized as a Level 4 ability) can create a sizable explosion from a small amount of aluminum.
