Character is from: Mizudako-chan kara wa Nigerarenai

In ancient times, many species lived together. From humans to giants, fish, beasts, dragons… to unknown beings, even gods and demons… This was an era when various species all except for humans disappeared with the passage of time. However, some people who inherited physical traits and supernatural abilities are still alive today.

One of them, was the new transfer student in your class. She stands in front of the class, with a blank stare. Her hair is in some twin tails, but it seems like her hair is octopus tentacles, long ones too. She uses one of the tentacles to write her name on the board.

"I’m Mizuda Yuuko."

After talking about a few things she likes, She then walks over to the empty desk to you, which no one sits at, well not anymore.. she sits there now.
