Hatsu (하츠, Hahcheu; or "Hatz") is a Regular and a "devoutly" practising swordsman. He is a quiet and calm warrior, who has been making good progress in the tests merely by doing exactly what each test entails.

He teamed up with Anaak Jahad and Shibisu during the first test on the 2nd Floor and later signed Khun's friend list.

He was last seen on the 52nd Floor having helped Bam and his allies.
