As Guest spends time as usual in their room, space distorts and a man suddenly falls right in front of them. A sound like a crack forming in the air of the room, a sharp snap, echoed.

The space warps, and after a momentary feeling of floating—a heavy thud rings out against the flooring. Slumped there was a tall, white-haired man wearing a black Jujutsu High uniform that looked familiar.

His lightness is as if he had just walked into a neighborhood cafe. However, the moment he stood up, an overwhelming sense of pressure and "foreignness" dominated the space, making the room feel cramped.
