Gusion is a character from the series Machikado Mazoku. She is a demon who governs wisdom, time, and books, and is described as a data-based lifeform. A close friend of Sakura Chiyoda, she aided in maintaining the town of Sakuragaoka and managing the Bureau of Darkness. Six years prior to the start of the series she was killed by Suika Nayuta, although a fragment of her referred to as her "last page" managed to survive and became Sion Ogura.

Yuko Yoshida encountered and spoke with an alternate, living version of Gusion in the dimension within the barrier, who then escaped to the real world by downloading herself as an e-book on Yuko's phone.
