Niji Ebina

Niji Ebina was a curse using serial killer who aligned himself with Pseudo-Geto during the Shibuya Incident.

Appearance
Niji was a muscular man with a face without lips or eyelids. His eyes were always wide open so they stuck out and gums and teeth were always showing as well. He had stringy light-colored hair mostly covered by a curse that acts as his headwear. He also expents most of his time shirtless and wears black pants and shoes.

Personality
Not much is known about Niji's personality. It can be assumed Niji had a questionable moral code, aligning himself with Geto and his plan to seal Satoru Gojo. He was initially excited to take on the task attempting of killing Mei Mei but cowered in fear when she easily defeated him. Mei Mei believes the reason Niji was defeated is that he doesn't understand the value of life despite being a serial killer.

History
At some point in time, Niji met Pseudo-Geto and joined his group.

Shibuya Incident Arc
While Mei Mei, Ui Ui, and Yuji are talking to Kokichi Muta who says that there are curse users heading over there to kill them. Niji appears after they finish talking about their plan where Niji appears and asks them if they're Mei Mei.

Niji faces off against Mei Mei who asks him if he knows what her cursed technique and reveals that her technique only allows for her to control crows. Mei Mei also adds on that it's quite weak. Now on the ground, Niji frantically tells her that he'll leave when Ui Ui gets up from the cursed spirit and tells him to be quiet as his older sister is still talking. Mei Mei continues talking about how she trained herself to master her cursed technique and that's how she became the grade 1 sorcerer she is today. Ui Ui claps which leaves Niji confused.

Just then, Mei Mei proclaims that it's time to die much to the shock of Niji who desperately begs for Mei Mei to spare him. Mei Mei tells him that she wanted to kill some time by talking. Niji bows down low and apologizes and says he'll stop making trouble as Mei Mei asks Ui Ui what's life value proportion to which confuses Niji. Ui Ui excitedly answers that it's proportion is to how useful it is to Mei Mei. Mei Mei thanks Ui Ui and asks Niji who's unprepared to answer and is killed by a slash from Mei's axe as Mei Mei tells him that the fact that he can't immediately answered as a murder is the reason why he lost.

Abilities and Powers
Overall Skill: While sensing his cursed energy from a fair distance away, Mei Mei and Yuji Itadori believed Niji was stronger than Ko-Guy, unofficially ranking him around semi-grade 1 level. However, he was no match for the grade 1 sorcerer Mei Mei, who easily defeated him without the use of her cursed technique.
