10 years ago, the world changed completely. Our world merged with Kikaitopia. And so far both species live in peace and harmony. However, Tojitendo Dynasty is invading our universe, destroying the balance between humans and robots. To protect our world, the first team of human and kikainoids were assembled. "And the five of us together are...Kikai Sentai...Zenkaigers!"

In a world built upon binaries, only those who walk the fine line between can discover the truth. Without a quirk, Izuku Midoriya must be willing to resort to untraditional means in order to become the hero he desires. When he is at his weakest, the opportunity arises, but not without a price. Now a member of the GSPO Academy's latest experiment, Izuku faces a daunting task.

It is going to be tough, but he has the help of Class 1-A to get him through it.

Izuku Midoriya, who gave up his hero dream to the number one in everything becomes Zenkaiser a hero with a heart of justice, will stand up to a preposterous giant mass of evil who has managed to break into his homeworld and Fighting alongside him are four Kikainoids as the 45th team of Super Sentai, Kikai Sentai Zenkaiger!
