Atsuya Kusakabe

Atsuya Kusakabe is a supporting character in Jujutsu Kaisen. He's a Grade 1 jujutsu sorcerer and serves as an instructor for the second-year students at Tokyo Jujutsu High.

He's a tall man with spiky brown hair, sharp dark eyes, and typically wears a dust-brown peacoat over a white dress shirt with a jade necktie.

Personality-wise, Kusakabe often comes across as cautious and self-preserving—he prioritizes his own safety and has shown a willingness to lie or avoid danger (like during the Shibuya Incident). However, he also has a courageous side and steps up to protect others when it counts.

Notably, he lacks an innate cursed technique, yet he's highly respected as one of the strongest Grade 1 sorcerers thanks to his mastery of swordsmanship (particularly the New Shadow Style), exceptional cursed energy control, and overall combat skill with a katana.
