At UA Academy, not even a violent attack can disrupt their most prestigious event: the school sports festival. Renowned across Japan, this festival is an opportunity for aspiring heroes to showcase their abilities, both to the public and potential recruiters. However, the path to glory is never easy, especially for Izuku Midoriya—whose quirk possesses great raw power but is also cripplingly inefficient. Pitted against his talented classmates, such as the fire and ice wielding Shouto Todoroki, Izuku must utilize his sharp wits and master his surroundings to achieve victory and prove to the world his worth.

As summer arrives for the students at UA Academy, each of these superheroes-in-training puts in their best efforts to become renowned heroes. They head off to a forest training camp run by UA's pro heroes, where the students face one another in battle and go through dangerous tests, improving their abilities and pushing past their limits. However, their school trip is suddenly turned upside down when the League of Villains arrives, invading the camp with a mission to capture one of the students. Boku no Hero Academia 3rd Season follows Izuku Deku Midoriya, an ambitious student training to achieve his dream of becoming a hero similar to his role model—All Might. Being one of the students caught up amidst the chaos of the villain attack, Deku must take a stand with his classmates and fight for their survival.

Yukiteru Amano is a shy middle schooler who regularly keeps track of what he does in his daily life by writing down all of his activities on his phone—a digital diary. Despite having no friends at school, Yukiteru is frequently seen talking to his supposedly imaginary friends Deus Ex Machina, the god of time and space; and Deus' servant, Mur Mur. One day, Yukiteru wakes up and discovers that certain events of his day are preemptively displayed on his cellphone. While initially dismissing it as a coincidence, he slowly realizes that the incidents written in his phone actually take place in the near future. After spending the day benefiting from this new asset, Yukiteru learns that his classmate Yuno Gasai possesses a similar diary. As the two team up to defeat an odd pursuer and head back to their respective homes, Deus Ex Machina explains that they—alongside 10 other contestants—have been drawn into a survival game whose victor will become the deity's successor. With no other options, Yukiteru and Yuno must use their cellphones—now called Future Diaries—to survive this unforgiving battle royale.

Fifteen years after a cataclysmic event known as the Second Impact, the world faces a new threat: monstrous celestial beings called Angels invade Tokyo-3 one by one. Mankind is unable to defend themselves against the Angels despite utilizing their most advanced munitions and military tactics. The only hope for human salvation rests in the hands of NERV, a mysterious organization led by the cold Gendou Ikari. NERV operates giant humanoid robots dubbed Evangelions to combat the Angels with state-of-the-art advanced weaponry and protective barriers known as Absolute Terror Fields. Years after being abandoned by his father, Shinji Ikari, Gendou's 14-year-old son, returns to Tokyo-3. Shinji undergoes a perpetual internal battle against the deeply buried trauma caused by the loss of his mother and the emotional neglect he suffered at the hands of his father. Terrified to open himself up to another, Shinji's life is forever changed upon meeting 29-year-old Misato Katsuragi, a high-ranking NERV officer who shows him a free-spirited maternal kindness he has never experienced. A devastating Angel attack forces Shinji into action as Gendou reveals his true motive for inviting his son back to Tokyo-3: Shinji is the only child capable of efficiently piloting Evangelion Unit-01, a new robot that synchronizes with his biometrics. Despite the brutal psychological trauma brought about by piloting an Evangelion, Shinji defends Tokyo-3 against the angelic threat, oblivious to his father's dark machinations.
