Tatsuki Fujimoto 17–26: Mitsuko and Kyoko Ebara

They're sisters who are competing each other for the best nude painting at their school for its annual art competition once per year as part of its tradition. Mitsuko is the older sibling, and Kyoko is the younger one. After finding out her little sister won that year's art contest thanks to the naked painting of her older sister, Mitsuko decided to do the same on Kyoko just to win and to get her revenge after enduring relentless teasing and humiliation from her classmates due to her being in her birthday suit in front of everyone. Even after Mitsuko won the next year's art contest with a better painting of herself, she ended up living with her sister at Tokyo after moving out of their house.

Tatsuki Fujimoto 17–26: Nayuta

She's a demonic mage who thought to bring the end of the world due to her horrific slaughtering on animals for food and destructive, dark magic since she was born. She speaks in a cursed way such as "Destroy, rot, ruin!", "Bloody, gory, smash.", Kill, torture, wrath." and was held responsible for the deaths of her parents and the suffering of many people. Despite the challenges she faces, her older brother, Kenji, remain committed, working diligently to care for and protect her and tried to keep her out of trouble. She spends her time at home reading books, writing words, trying to speech in first-person and to create weapons like swords with her magic. She never likes being misjudged due to her horns on her head and nearly started to cause havoc around her. This is from "Nayuta of the Prophecy".
