Kenka no Gokui 6

All Might and Deku accept an invitation to go abroad to a floating and mobile manmade city, called 'I-Island', where they research quirks as well as hero supplemental items at the special 'I-Expo' convention that is currently being held on the island. During that time, suddenly, despite an iron wall of security surrounding the island, the system is breached by a villain, and the only ones able to stop him are the students of Class 1-A.

A mysterious group called Humarize strongly believes in the Quirk Singularity Doomsday theory which states that when quirks get mixed further in with future generations, that power will bring forth the end of humanity. In order to save everyone, the Pro-Heroes around the world ask UA Academy heroes-in-training to assist them and form a world-class selected hero team. It’s up to the heroes to save the world and the future of heroes in what is the most dangerous crisis to take place yet in My Hero Academia.

In the spring, male student Makoto Yuki transfers to Gekkoukan High School. However, as he heads to his new dormitory, listening to the music on his headphones, he is stopped. More precisely, time has stopped, and the people who were around him turn into coffins. Makoto learns that this period of time hidden between the minute of midnight is called the Dark Hour, a time when monsters called Shadows appear. Suddenly made the leader of his fellow classmates Yukari and Junpei by his upperclassmen Mitsuru and Akihiko, Makoto must learn empathy, his connection to his comrades, and the meaning of death. With the power of his Evoker aimed at his head he awakens a Persona and fights against the Shadows threatening to attack his world from the mysterious tower of Tartarus.

After realizing the value of life and the importance of his own allies, Makoto finally got his smile back. He finds himself learning more about those comrades and getting closer to them. Makoto wishes that everything will continue just as they are. However, little by little, the pieces and people in Makoto's new, happy life begin to fall apart.

Class 1-A visits Nabu Island where they finally get to do some real hero work. The place is so peaceful that it's more like a vacation... until they're attacked by a villain with an unfathomable Quirk! His power is eerily familiar, and it looks like Shigaraki had a hand in the plan. But with All Might retired and citizens' lives on the line, there's no time for questions. Deku and his friends are the next generation of heroes, and they're the island's only hope.

Thirteen year old Sam Cleary suspects that his mysteriously reclusive neighbor Mr. Smith is actually the legendary vigilante Samaritan, who was reported dead 25 years ago. With crime on the rise and the city on the brink of chaos, Sam makes it his mission to coax his neighbor out of hiding to save the city from ruin.
