Atsuhiro Sako (迫さこ圧あつ紘ひろ Sako Atsuhiro?), also known as Mr. Compress (Mr.ミスターコンプレス Misutā Konpuresu?).

Compress (圧あっ縮しゅく Asshuku?): Atsuhiro's Quirk allows him to "compress" anything in a spherical area around his arm into a small, marble-like object without actually damaging it. He can only compress his target if he is touching it.

The weight of the target is reduced alongside them, making them very easy to carry. If used on a person, it effectively entraps them, terminating the fight instant
