Episode 11 sees the arrival of another unusual transfer student. This time, it’s a boy named Itona Horibe, who is accompanied by his guardian, Shiro. Itona makes a grand entrance when he smashes through one of the walls and takes a seat in the back row. If Itona’s eyes and the way he carries himself didn’t tip off the viewer that there was something unusual about this new student, then the fact that he can walk in from being out in the rain without an umbrella and not be wet made it clear that there was something unusual about this character. And if that didn’t weird the class out enough, then Itona’s declaration of being Koro Sensei’s brother sent serious ripples throughout the class. There were some amusing scenes depicting the students’ imagination that reference other anime. I distinctly caught a Dragon Ball Z reference, but I’m sure there are other iconic anime referenced as well that I didn’t catch because it went by so fast.

Itona challenges Koro Sensei to a face off after school, which sees the desks being arranged into a ring. As part of the face off, a rule is made that stepping foot outside of the ring means death on the spot. Itona surprises both Koro Sensei and the students when he reveals that his hair is actually tentacles and that he’s able to slash at Koro Sensei’s tentacles rather easily.

For most of the face off, it appears that Itona will end up being the ultimate victor. When it seems that Koro Sensei’s death is almost certain, Nagisa realizes that he feels disappointed that it would be Itona and not one of the other members of the class who will succeed. This disappointment that Nagisa feels plays an important part near the end of the episode after Koro Sensei is able to get the upper hand and send Itona flying out of the window. But in Koro Sensei’s regular style, he agrees to spare Itona’s life if he will stay and learn with everyone in the class. Itona goes berserk because he doesn’t like to study, but he is brought under control. Shiro takes Itona out of the classroom because he just wasn’t ready for school.

But this incident makes the members of Class 3-E take the task they’ve been given more seriously, especially after Koro Sensei reveals that he’s an artificially created lifeform but won’t reveal more so they can learn more about the truth after they’ve killed him. This change in attitude sees the students approaching Karasuma for additional assassination training, and he plans to work them hard.

I guess the explanation of Koro Sensei being an artificially created lifeform makes sense, especially considering that a couple of brief flashbacks of his show him in what appears to be a destroyed lab. And the artificially created lifeform explanation also explains how Itona can be his brother. But now this explanation opens up a whole new can of worms and creates even more questions that will hopefully be answered as the series progresses.

Episode 11 marks the halfway point for Assassination Classroom, and the way the ending of the episode was written reinforced the idea that the series will be kicking things up a notch for its second half. It’s going to be interesting to see what directions the story will take during the series’ remaining 11 episodes.
