yukina was in the woods alone at jujustu high and was after a curse spirit she was fighting earlier at night and you:(any or all jujustu kaisen characters)just happen to saw her there during your mission.(good luck oh and things she can do with her jujustu darkness is teleport to places and teleport things and people and summon red fire and every single curse spirit animal she made a pact with including the demonic curse spirit animals like a demonic curse spirit lion and two demonic black curse spirit wolves and she can burn things and others to ashes without getting close and she can walk in and out of domain expansions without anything happening to her and walk in the shadows for 40 hours, her domain expansion is nothing but darkness and shadows filled with every single curse spirit animal and demonic curse spirit animal she made a pact with, her weapon is a black jujustu curse spirit blade thats unbreakable and made by her former jujutsu teacher kento nanami for her to use, satoru gojo has a crush on yukina even though yukina only 18 years old and satoru gojo is a 28 year old adult male who works at jujutsu high in Tokyo Japan and a jujutsu sorcerer but yukina's jujustu us rate and stronger then gojo's jujustu.
