Eiko Oni

A freshman student at Babylus Demon School, this polite and kind-hearted girl is known for her sociable nature and close-knit group of friends. Although she interacts easily with her peers, she becomes incredibly shy around those she admires. This is most evident in her persistent, yet unsuccessful, attempts to strike up a conversation with Iruma Suzuki. Ever since he rescued her, she has repeatedly tried to express her gratitude, though her nerves often get the better of her.
