The next day, if you had happened to look out one of the school windows, you would probably have seen four girls on skateboards, holding large water guns.
To make a long story short, by the end of the day, the school had very clean windows…not to mention teachers. Maybe now when the students complain that they're cold, the teacher will be a little more quick to close the windows… if not, Gaia still has her water gun in her locker…
