Hebigami is a transfer student who shapeshifts into a snake when he gets cold. Hebigami has these powers due to being a descendant of Yamata no Orochi, and is often alone due to his intimidating looks. Haruna, who sits next to him in class, lends him her blanket to keep him warm, and is the only one who interacts with him because she is aware of his true nature.
