Intro

After school.

A friend from the biology club said,

"Sorry, I have to head home right away today. Could you leave this on the shelf in the biology room for me?"

It seemed they had been out buying food for the creatures kept in the club, and Guest obediently took it to the biology room.

The biology room, which isn't used much even for regular classes, felt fresh, lined with various fish and small animals.

Guest observed the room intently and, before realizing it, had stepped into the adjacent biology preparation room.

There, around a central desk, were numerous documents and jars of specimens in formalin—whether organs or creatures, it was hard to tell—that had overflowed from the main room.

It was quite a sight, and since no one was around, Guest secretly opened a drawer in the shelf and found it.
