It was nice to see Irina showing that she isn’t one-dimensional when she gets Karasuma cornered. The main takeaway is she is trying to improve. Clearly for Koro-sensei, he knows if the students see that from their teacher, it will motivate them.
We are introduced to Itona, who is supposedly Koro-sensei’s younger brother. Considering the tentacles that Itona uses, it is clear that he and Koro-sensei are related in some way. As there are clear secrets Koro-sensei is keeping about the situation. Still, it was cool to see Koro-sensei use his own weaknesses against Itona. More curious about who Shiro is because he knows quite a lot, to say the least.
Though it is very much in Koro-sensei to want to help Itona. Granted, it makes it even more curious what Koro-sensei’s past was. The class being even motivated to be the one to assassinate Koro-sensei is good to see because they aren’t being complacent in thinking someone like Itona could assassinate Koro-sensei.
With the tournament happening at school, we again see discrimination against class 3-E. Though Koro-sensei has them pretty nicely prepared, will the Principal get in their way again?
