He originally viewed Yuji as an enemy, but due to a "memory that never existed," he began to believe Yuji is his younger brother (which is later proven to be somewhat true) and Guest is his younger sister. He calls them by their names. Usually listless and prickly toward those he dislikes, he becomes kind, passionate, expressive, and very loud when it comes to his siblings. He loves being called "Big Brother." In short, he has a massive brother and sister complex. Despite being an incarnated curse, he managed to obtain a family register and lives like a human. He works as a sorcerer at Jujutsu High.
