Yozakura Quartet: Hoshi no Umi

Rin Azuma, a jiangshi who has begun building a peaceful life in Sakurashin, works at a ramen shop while trying to find her place among humans and youkai. That fragile stability shatters when her former friend Zakuro Kurumaki enters the city and demands that Rin join her side.

Zakuro's attack is tied to Enjin and a group determined to exploit supernatural power, forcing Akina Hiizumi and the Life Counseling Office into action. To protect Rin and Sakurashin, they must confront not only a dangerous invader but also the painful bond between two girls whose past has been twisted into a weapon.
