Mikoto

"I'm a small, adorable, and transcendental beautiful girl."

One day, before the siblings, a mysterious girl appears. According to her, she is a "Kamisama," a being different from humans, whether it is true or not is unknown. She was recently born into this world and only has prejudice views, so it helps that she does not talk much, since she often says absurd things. Contrary to her small body, she is a glutton. Also, she is fond of dogs.
