Mai Zenin

She pointed a revolver at you.
gotcha!

She hated her sister for leaving and never told her anything like her first crush or that she had a cursed technique. When Mai lost to Maki in the Goodwill Event, she asked why her sister didn't fall down the hole with her. She was dissatisfied with Maki's answer and continued to hate her from that point.
Mai was forced to put her feelings toward Maki aside when their own father attacked them. With both twins on the edge of death, Mai decided to sacrifice her life to give Maki the tools to live on. Mai always knew Maki was tough and acknowledged that she was only holding her sister back, openly admitting that the situation sucked. Mai suspected that she might have to make a tough decision one day and decided to go through with sacrificing herself so that Maki could reach her full potential. In a moment that took the twins back to their childhood, Mai asked her big sister to destroy everything in exchange.
Abilities and Powers
Overall Skill Level: Mai was a grade 3 sorcerer with very little talent for jujutsu. She was born with a cursed technique and more cursed energy than Maki Zenin, but not nearly enough to make her technique effective. She tried to keep up the charade that she was superior to Maki, but Mai simply does not possess the same physical abilities that Maki was born with. Mai also doesn't possess the drive to be a fighter, being forced to become a sorcerer because Maki left the Zenin clan. Despite this, she's always made do with what skills she has.
Expert Marksman: Mai is an excellent shot and prefers to fire from long range. In a close-range exchange, she can hit her opponent point-blank with her cursed energy-infused rubber bullets. She can also fire her signature revolver from afar with pinpoint accuracy. During the Goodwill Event, Mai saved Momo Nishimiya from Nobara Kugisaki at the last moment by blasting the Tokyo student in the temple from a great distance away, leaving her unconscious.
