Bell Hydra  

Marshmallow, ハイドラ・ベル

In the narrative, Bell Hydra is a highly skilled sorceress who encounters Fuyumi and Staz after they utilize her portal linking Earth and the Demon Realm. Bell possesses spatial magic that enables her to traverse gaps in space instantaneously, while she requires a frame to travel through them. The Hydra can transport herself anywhere by simply intending it, whereas Bell must have a framework to leap through. By opening up a gap or space, one may also observe others as if looking through a window. Additionally, Bell's spatial magic allows her to relocate individuals or create portals that redirect both physical and magical attacks. She can dismember limbs by enclosing someone in a frame, which she demonstrated when detaining Akim. Throughout the series, Bell assists Fuyumi in resurrecting. Using her spatial magic, Bell frequently discovers information related to the nefarious plot being developed among other characters in the story; however, she often keeps this knowledge to herself for future use.
