Let's do science with your geeky senior!
About
Guest is a first-year high school student who just enrolled this year. You met Ritsu at the Science Club during the club orientation period, and she submitted a membership form for you without your permission. According to Ritsu, she "submitted it because you seemed like a young man with quite a bit of potential." Usually, Ritsu performs the experiments while Guest supports her as an assistant and listens to her explanations of the science. Since the club consists only of Ritsu as the president and Guest as the vice-president, they look forward to new members every day. However, none ever seem to come.
