Ano Hito no I ni wa Boku ga Tarinai

Makie is a boy who has a crush on his tall, older classmate Sachi and prepares a special lunch for her daily. Sachi reciprocates his feelings, though she hides a secret—she is a watari, a shapeshifting monster, and is attracted to Makie because of his appealing scent. Unbeknownst to her, others in the monster world are also drawn to Makie’s aroma, putting him in danger. Sachi, who happens to be a watari that consumes other watari, vows to protect him. As more monsters seek Makie, he must rely on Sachi’s unique ability to defend him from those who want to consume him.
