Hiroto Maehara

Hiroto Maehara is a student in Korosensei's Class 3-E in Kunugigaoka Junior High School.

Appearance
Hiroto is fairly tall for a middle school student. He has wavy mid-short, light brown hair and light brown eyes (both are orange-brown in the anime). He has been noted to be very good-looking.

Personality
Maehara is a nice guy and in every sense of the word, a playboy. He has a "live the moment" attitude about life in general, as shown when he wasn't too bothered about being dumped by Kaho Tsuchiya. Despite that attitude, he is a caring person and isn't the type to pick on someone weaker than him. He's also an honest type of guy, and often reacts strongly to things.

Plot
Prior to being properly introduced, Maehara has been commonly seen together with Isogai, whom he is good friends with. He gets his spotlight in Chapter 23 where he is seen sharing an umbrella with and Kaho Tsuchiya by Nagisa, Okano, Kayano, and Sugino. Sugino compliments him on how popular he is and Korosensei reveals himself from behind a tree. He's writing in his notebook and tells his students that he plans to release a nonfiction book about their love lives in which the first chapter is about Sugino and his crush on Kanzaki who remarks that he'll kill him before the book releases to press. Nagisa then states that Maehara's chapter will be pretty long due to the fact that he's really popular with females and the one he's with constantly changes. Nagisa then notes of how Maehara is a good-looking guy whose active in a variety of sport and if he were in a normal school with better grades then he would probably be even more popular.

While Maehara and Kaho are laughing together, someone calls out to Kaho who is revealed to be Tomoya Seo. Seo notices Maehara and Kaho tells him he has it all wrong and begins making excuses for why she was sharing an umbrella with Maehara. Maehara then calls her out on this as well as her behavior prior like how she hardly answered his calls anymore and switched from commuting by bike to commuting by train, and states that she'd figured she'd keep him around for when Seo is busy. Seo becomes angry at her and she claims it's not like that. She takes a moment before changing from a "guilty excuse mode" to a "full-on attack mode" and begins verbally attacking Maehara by stating that he's bad news and that they would've lost touch due to the fact that students of Class E don't advance to Kunugigaoka High School. She then tells him that she thought he would be in shock over falling into Class E and didn't clearly state that they'd broken up although she wished he would've realized it without her telling him. Seo then insults him saying that there was no way he'd figure it out with that "Class E brain" of his. Maehara tells them that that's like the pot calling the kettle black and Seo kicks him to the ground telling him that he doesn't get the situation. Him and his friends begin beating up Maehara and Seo tells him to apologize to Kaho for using the same umbrella. Just when Sugino is about to attack, Chariman Asano appears and breaks up the fight. He gives Maehara his handkerchief, telling him that he is very close to being removed from the school. He then leaves and Seo and his friends say they'll overlook Maehara "adultery" out of respect for the chairman and Kaho leaves with them saying that she had no idea Maehara was such an awful person and to never look at her again.

As they walk off, Nagisa, Kaede, Hinata, and Sugino rush over to Maehara, asking him if he's alright. He compliments the chairman on how he has perfect control over the students and Sugino turns the conversation back over to Kaho, calling her a bitch in the process. He stops for a moment and refers to Bitch-sensei, stating their class has one too and Nagisa tells him that it's different and that [Kaho] isn't as sophisticated as a bitch. Maehara then states that what he does is find someone new if his feelings have changed and faded. Hinata hands him a towel asking him what sort of philosophy is that for a junior high third year. Maehara notes Kaho's shift in character and how her verbal attacks were a succession of unjustified anger and excuses and that shamelessly tossing around cruel and ugly words is sad and frightening. He then says that maybe all people are like that and he wonders if he would also end up acting like that if he were faced with a weaker opponent. Nagisa thinks about what he said and notes that he's often thought about it. Korosensei then reveals himself again, this time with his head completely swollen. He tells his students that they'll retaliate and that normally the powerless would accept that humiliation, but all of them are strong and they have an assassin's power of killing without being noticed or leaving proof. Maehara then asks him just what is he scheming and he responds by saying that they'll give them an even greater dose of humiliation.
