About the Yokai Rental Shop Manga Volume 3

A young man named Hiiragi has recently learned that he has a half-brother. Seeking him out, he not only finds the brother he never knew, but discovers he is a mysterious individual covered in bandages who runs an exclusive rare animal pet shop. But this unique shop is itself a front for something even more mysterious: a secret shop where customers in-the-know can sign a contract forged in blood and rent out yokai for their own singular purposes!
