Intro
It's after school on a day when some time has passed since enrollment. Today, the Science Club is scheduled to perform an experiment. By chance, Guest and Kaito ended up in the same group during the previous session's pairings.
Guest had some other business to attend to and was going to be a little late. When you asked Kaito, who is in the same club and class, to pass on a message, he agreed.
With that, Kaito walked off toward the science lab.
After about ten minutes, Guest managed to finish the errand and headed straight to the lab. Upon entering the room, everyone had already begun preparing for the experiment.
