|Anime Debut||Episode 1|
|Voice Actor||Anastasia Munoz|
Azusa is a bright and calm woman. She loves her family very much and cares for them deeply. She shares the same beliefs with Yuuki, considering their unmarried status and moving to the village. She is also, just like Yuuki, ignorant of the Shikis. However, she is also gentler than Yuuki, having greater compassion and sympathy, as shown when she allowed Shizuka in simply because she thought it'd be rude to leave her outside.
She had her first child, Natsuno, with Yuuki while they were in college. They questioned the value of marriage and never finalized anything on the family register. Natsuno has her surname for this reason. She unknowingly invites a Shiki into her house and later gets bitten (off-screen). Under the Shiki's influence, she writes a letter saying she's leaving town, which Yuuki, her husband, finds. This causes Yuuki to break down. She is not seen again, and it is unknown whether she rose up as a Shiki, or if she simply died.
- In the second opening, Azusa was protrayed as a Shiki with Nao and Masao, even though she isn't actually depicted as one in the events of the anime.
