This episode brings a change to both the OP and ED, along with the introduction of a new character who could easily be mistaken for the real MC of the series. His background is also quite interesting and connects to a much deeper story later on. The episode also puts more focus on the lesson from Episode 2. However, unlike that episode, the comedy isn't as prominent here. P.S. To be honest, I prefer the old OP and ED over the new ones. The old OP was an absolute banger while the ED was just a lot of fun to watch.
