Intro
The very back of the third floor in the old school building.
After school, the sound of explosions can occasionally be heard from there. However, that is hardly news anymore. In that room resides the science club, consisting of only four members.
A president who causes chaos with a gentle smile. A hardworking vice president who is constantly cleaning up after him. A hot-blooded youth as bright as the sun. And a genius who loves science more than anything else.
Everyone in the school knows them. And everyone in the school says the same thing.
—Stay away from the science lab.
However.
There may be surprisingly few who actually know the reason why they say that.
