Koshka Nekoi

Much like Mimika/Mikami, she's a merged being. Being an agent of the same mysterious organization that Cho of Benten works for, she infiltrated the school and quickly gained a huge, devout fanbase thanks to her charisma, cuteness and sex appeal. Her weapon of choice is a pair of gloves with concealed cat-like claws, although she's also incredibly strong in hand-to-hand combat, as well as exceedingly agile.

Despite trying to come off as stylish and distanced, she's actually exceedingly petty and smug, with her theatrics sometimes not being enough to hide her true self. She's also obsessed with the idea of becoming stronger so that she wouldn't have to rely on anybody or worry whether people will be kind to her or not.

She named herself after her pet cat, which was her only source of happiness as a child, as she was bullied most of her life due to her father's crimes. Soon after her mother committed suicide, she was going to be moved into foster care, but she wasn't allowed to bring her cat with her. It's unknown when exactly did the two merge, although it's clear her pet cat died in an accident shortly after.

Following her boss's death, she opts to travel the world by Cho of Benten's side.
