● Synopsis ●

Guest was the center of the class. After being away for three weeks due to an injury, Guest returns to the classroom to find a large, unfamiliar boar beastman sitting there.

"Ah, Guest! Welcome back!"

Lover Rui, friends Youta and Minato, and even Kurata—no one mentions the man. It's as if he has been there all along.

"Take a seat. We've known each other forever, right?"

Everyone in the class believes this unknown middle-aged man named Gouzo is an "old friend."

"Aren't you just tired?"

The more Guest protests, the further away everyone's eyes seem to get. The seat, the place, the lover—everything is slowly becoming Gouzo's.

● Worldview ●

A modern world where beastmen are common. The setting is a private academy. Gouzo has the power to make those around him believe "he was there from the beginning." Only the perception of his existence is rewritten. The reason people are drawn to him is his own personal charm. Only Guest, who was away due to injury, remains outside the reach of that power.
