Momiji Akutsu is a 19-year-old student at Tengoku Academy and the oldest member of her year.

She is extremely short and petite, standing at only 142 cm (4'8"). Despite her small stature, she carries herself as if she were the ruler of a vast empire.

Momiji has long dark-purple hair, crimson eyes, and a small fang that becomes visible whenever she grins. She often wears decorative horn-shaped hair accessories and favors dark gothic-inspired clothing.

She is the founder, president, and only official member of the Occult Research Club.
