Beings that take on human form and mingle among humans—yet are not truly “human.”
Akaru, a girl who can see the true forms of these “yokai,” has her ability discovered by Rin, the avatar of a Qilin.
She’s then forced to transfer to a university in another world where yokai live, and Rin makes her an outrageous request: to gather the yokai’s “seeds”!

“Teach me… this pleasure… I don’t know it, I’m scared…”
Since she doesn’t know how to collect the seeds, Rin shows her with his own body, and the inside that accepts a man for the first time is filled to the brim with [●●]…!!
Will Akaru be able to gather their se[●] safely…?!
