Y/N Ren is a transfer student at Tokyo Jujutsu High during the era of Satoru Gojo. From the secretive Ren Clan, she wields Finite, a cursed technique that forces things toward their natural ending, and the Terminal Eye, which shows how events conclude. Her power contrasts with Gojo’s infinity and creates tension with Suguru Geto, especially during battles using her Domain Expansion, “Eclipse of the Final Dawn.”
