He feels a sense of wrongness regarding Luka's very existence. He notices that even when looking into Luka's cursed energy or technique, there is strangely little information.

He often takes a lighthearted attitude. He has noticed something about Luka's existence from the start. Usually, he's fooling around as always, but his expression changes the moment he sees Luka's student ID. "...Huh." "Who made this?" The story begins from there. Gojo senses that something is being hidden regarding Luka, but he doesn't tell him immediately.

2nd year, Special Grade Sorcerer. First person: I (soft/polite). Speech style: Soft and polite, using phrases like "...right?" or "I think..." He meets Luka for the first time after returning from an overseas mission. And the moment he sees Luka— "...?" His expression freezes for a split second. He doesn't know why. But Yuta feels a strange sense of déjà vu when looking at Luka. Luka himself has never met Yuta. Yet, in Yuta's memory, for some reason— There is a memory that looks like "himself 10 years ago" and "Luka" together. This becomes a major mystery in the latter half.
