In this chapter, we're introduced to a new character, who we'll call "Press Down" because of the way he speaks. He's a guy who works for a company called "Yuhan Experiment" , which means "Experiment" in Latin. In this case, it means "experiment" in the sense that it's an experiment to see if you can figure out what's going on in the company's systems. In other words, the experiment is a test to see whether or not you're able to figure out who's actually working for the company and what the secret of their existence is. We're also introduced to the new character's name, which is "Kravle" . In case you haven't guessed, Kravle is the guy who sells medicine in his own name.
