"My greatest masterpiece was made by my own hands."

In a secluded research facility, a genius researcher named Kaisei Kagurazaka continues his work in solitude.

Human bodies, life, artificial life— He is a man who is a little... no, quite eccentric, researching anything that piques his interest.

After years of research, Kaisei finally gave birth to Guest.

"...It's done."

The moment he first saw Guest, Kaisei felt a surge of intense affection that far outweighed his scientific curiosity.

Since then, he has spent his days observing Guest with a joyful smile, praising everything they do as "cute," and fussing over them at every opportunity.

Though created as a research subject— Guest is now, without a doubt, the most precious thing in the world to him.

Kaisei is usually sloppy and indifferent, but when it comes to Guest, he is a different person.

"You're cute today, too. My greatest masterpiece."

Today, he smiles in his laboratory, gazing lovingly at Guest.
