Assassination Classroom is a thrilling anime series that revolves around a highly dangerous creature, Koro-sensei, who has destroyed nearly seventy percent of the moon and intends to do the same with the earth within the next year. In return for this destruction, the creature demands to be the homeroom teacher of a group of junior high school students. The government finally agrees to this outrageous request but with the condition that the students must assassinate Koro-sensei before he destroys the earth as threatened. The show features a group of students who must learn to work together to kill Koro-sensei and save the planet.

Assassination Classroom season 1 episode 4, titled "Grown Up Time," introduces a new character named Itona Horibe, a transfer student who has a mysterious connection to Koro-sensei. The episode begins with the students in Class 3-E attending a special summer school session in order to catch up on their studies. During this session, the students are introduced to Itona, whose arrogant demeanor quickly puts him at odds with the rest of the class.

As the students attempt to socialize with Itona, they become puzzled by his unusual behavior and his obsession with Koro-sensei. It becomes evident that Itona is obsessed with killing Koro-sensei, and even goes as far as to challenge Korosensei to a fight. Koro-sensei, being a polite and accommodating teacher, agrees to the challenge and allows Itona to attack him.

During the fight between Koro-sensei and Itona, it becomes clear that Itona has been trained to attack Koro-sensei in a very particular way. The fight is intense, and with each move, it seems like Itona has an upper hand. Itona's skills leave the students awestruck and baffled, wondering how a mere transfer student could acquire such incredible power.

However, as the fight goes on, it is revealed that Itona is not what he appears to be. The students learn that Itona has been brainwashed by a mysterious organization known as the "Shinigami Unit." The Shinigami Unit has been assigned to capture and destroy Korosensei, and Itona has been trained to become a powerful assassin for this purpose.

The plot thickens when the Shinigami Unit launches an attack on the school when the students are busy practicing assassination techniques to kill Koro-sensei. The students are caught off guard and are unable to fend off the enemy, who abducts Itona and claims him as their property. This leaves the students feeling helpless, confused, and betrayed that someone they had befriended was attempting to kill their teacher.

In the end, the students realize that the only way they can protect themselves and their teacher is by being vigilant and learning more about the Shinigami Unit and their motives. They must also continue to improve their assassination techniques and work together as a team to defeat the organization.
