To the common eye, Y/N Midoriya seems like your normal teenager. But beneath him lies great strength. Which is insane, cause he has no quirk, like his little brother Izuku. He mostly uses his power to protect his younger sibling from bullies, monsters, and villains. But after a crazy day, All Might offers Izuku his quirk, and Y/N joins his little brother on a journey to achieve their dream of becoming the greatest heroes in the world. And who knows? Maybe he might find someone to give him a challenge. Cause overwhelming strength is so... boring. There may or may not be lemons later on. You will just have to wait. I don't own MHA, or OPM, or any of their characters. Only the story. The rest belong to their respective owners.

Y/N, the son of the one punch hero Saitama, has teleported to another world after being sucked in by a mysterious portal that appeared. He ended up in a world of Spirits and girls in mech suits. Will he finally find a challenge in this new world or will it still end in one punch. First thing that's important is looking for the nearest store.

After another battle, ending with a single punch. Saitama walks back to city Z carrying his bag of groceries. Feeling dejected from yet another day of defeating monsters so easily, he ponders to the heavens if there still a purpose for him. Just then, a portal suddenly appeared and swallowed Saitama. Now our hero is flung into a new world and facing new challanges. --- Don't own the characters and settings from both works besides the random ones I put in the story. OPM is owned by ONE and Invisible by Robert Kirkman. I do this for fun and my head is blocked with my other works.
