I wanted to open a canteen among the clouds and lie down, but I unexpectedly discovered that I was not a human being.
Grandpa is a dragon, so what am I?
Only later did I discover that these close friends were not human and had even joined some kind of alien academy.
The four pets left behind suddenly transformed. Who are they?
And what exactly does that mysterious organization that is spying on me want from me?
And the nightmare of the campus festival under the blood moon...
The only key to unlocking all these mysteries is hidden in my grandfather's diary that I have ignored for more than ten years.
I decided to go find Grandpa.
But this journey of "little dragon looking for old dragon" is far more dangerous than I imagined...
