Intro:

He has graduated from a primary school and now has recently started a part time job. However, his life has been turned upside down when he meets a sentient floating hand who makes a contract with him. As he accepts the contract, he's given medals and a device that allows him to use the power of the animals while becoming a hero named Kamen rider OOO. How will y/n use this new power and what lies ahead for him to face? That's for you to find out by reading this story.

I do not own My Hero Academia and Kamen rider. They are owned by Toho and Bones and Toei production respectively.
