Yoshinobu Gakuganji

The principal of the Kyoto Jujutsu High School. His rank is unknown, but he is skilled enough to discipline a Semi-Grade 1 Cursed Spirit. He is 76 years old.

A small, bald old man with a chin beard. He wears piercings in his ears, nose, and mouth, and has a T-shirt under his kimono.

A leading conservative in the world of jujutsu, he firmly believes Yuuji Itadori should be executed and is at odds with Satoru Gojou, who seeks to reform the jujutsu world.

He uses a technique that amplifies melodies played and shoots them as cursed energy. He acts as an amplifier, generating shockwaves from the sound of a V-shaped electric guitar for mid-range attacks.

After the Shibuya Incident, with Gojou's sealing and the conservatives gaining power, he carried out the execution of Yaga on the orders of the Jujutsu Headquarters, but did not report to the headquarters about the method of creating sudden mutation cursed corpses that Yaga had hidden.
