Mayumi makes a very small breif appearance when Tsukune brings Moka to the infirmary due to her blood consumption. Mayumi believes that Moka was exhausted. She suggested that Moka needs to eat well and sleep more so she can get better naturally. Mayumi then needed to be going and locks up the place.
- Mayumi's real appearance remains unknown due to her wearing bandages all over her entire body.
- However, her obvious resemblance to a mummy strongly implies that this is her true form.
