Shi Qu Lu, a student at the Magic Sword Academy, dreams of joining the Royal Spirit Research Institute. Only outstanding people who have advanced from magic to spiritual power can get in.
Senior Jin Yelai is a genius who was admitted to the Royal Spirit Research Institute through a special exception. He is Shi Qu Lu's idol.
The Royal Spirit Research Institute's latest achievement is turning spiritual power into spirit beasts that can help mages and swordsmen fight.
Shi Qu Lu wants a spirit beast of his own, so he goes to the institute's Spirit Beast Party. But instead, he finds an injured golden-crested spirit bat!
The bat has golden fluff on its head, reminding Shi Qu Lu of Senior Jin Yelai's golden hair in a photograph. He takes the golden bat home and lovingly nurses it back to health.
Lucky Shi Qu Lu also meets Jin Yelai at the party. The two hit it off for some reason, gradually get to know each other, and become close friends.
But why is the golden-crested spirit bat getting stranger the longer he keeps it? And why is Jin Yelai acting so weird, too?
Shi Qu Lu finally can't hold back. He shows Jin Yelai a photo of the golden-crested spirit bat and asks:
"Is that you in this picture?"
"Yes. I was still quite thin back then."
"...Don't change the subject, and don't make jokes."
"All right, it was me."
