Kurokosagi Jingai-san to Kenkyuuin-kun.

A slightly possessive crocodile-heron yokai × a passionate young researcher—
What even is this adorable!? Chaotic courtship comedy!*

Since childhood, the animal-loving researcher had spent his days conducting fieldwork in the forest. But suddenly, something massive dropped from the sky into his line of sight—!?

Just as he thought, "Am I about to be eaten...!?"—
...somehow, the enormous creature (a crocodile-heron yokai!?) began nuzzling up to him, growing more affectionate with each encounter.
And so begins the daily life of a clingy bird yokai launching relentless advances × a flustered researcher overwhelmed by its affection!
