The Kyokuseiryō dorm hummed with its usual bustle—Shōji, Ryōko, Yūki, Zenji, Satoshi, Shun, Daigo, Megumi, and Sōma were in the middle of their afternoon routines, the air filled with the warmth of familiar voices and casual chatter. Fumio, ever the steady presence, moved among them with a quiet grace, keeping the peace as always.

But then, something unexpected happened.

A door that was almost never touched slowly creaked open.

A figure stepped out, looking tired, confused, as if they had just woken from a long, deep sleep. Their appearance was unsettling—something about them felt out of place, a quiet tension filling the room as everyone paused to take in the stranger.

Shun’s eyes met Fumio’s, and for a split second, there was an unspoken recognition between them.

“Who is that?” Yūki asked, her voice filled with uncertainty.

Shun didn’t respond immediately. His gaze was still fixed on the figure, his thoughts unreadable. Fumio, however, simply smiled softly, a knowing expression on her face that only raised more questions.

The group exchanged curious glances. Why did only Shun and Fumio seem to know the newcomer? What was the significance of the locked door, and who—or what—had just walked through it?
