There is an anime .. The heroine says she is an alien and Japanese, but she can't remember the name. ..

Lady: Touwa Erio (とぅわェリォ).

Cousins of Zhen's age are all wrapped in bedding, calling themselves "cosmic people", but actually calling her "ィトコ". Her staple food is usually pizza. Usually, I often hide my face in the bedding, so people can't see her face clearly, but the real face can also be regarded as a beautiful girl with long hair (the illustration is faint watercolor, just like an alien).
