Astronomy Camp with Kato (III)

Yuki and Kato couldn't even introduce themselves to Amagi's mother as she had already dragged them both to one of the buildings in the observatory. By the title put on top of the door, Yuki knew this was a multimedia room, and when he entered it, he saw about twelve more teenagers wearing the same clothes as each other.

"Oh, I forget about this." Amagi's mother slapped her forehead in realization before she dug something from the corner of the room and gave it to the three teens. "Here, the official shirt of the camp, change yours first. Hiro-kun, you know where to do that."
