Y/N, an inter-dimensional hero. Y/N has become a complete legend in thousands of dimensions. Whether it is facing a monster, a disaster, a god, or other horrors, Y/N would always emerge victorious. Undefeated, unmatched.... Unbelievably tired. After spending much of his life fighting evil, Y/N wants nothing more than to return home. Of course as a reward for his heroism, he was sent to his home dimension, Earth.... Right?...

Meet (Y/N), the most powerful hero on earth... that no one has ever heard of. He's done it all, slay monsters, avert disasters, and save the planet and if there is one thing he's learned is that he REALLY wants a break. After deciding to have a normal life, (Y/N) has chosen to finish high school. And what better place to have a normal school life than Honnouji Academy!!!! Anywhere... Literally anywhere else.

12,000 years. 12,000 years inside a supposed metal coffin with the slimmest chances of survival. 12,000 years spent frozen after the downfall of humanity and all life on land. 12,000 years for the son of the world's greatest scientist to awaken out of his cold metal coffin. Awake in a new world so familiar yet so, so different than how he left it. The human race is famous for its adaptability and the creative ways they overcome loss. Now we see how the last human deals with defeat, loss, and the standstill he shall endure in this unforgiving new life. A/N: I'm bored out of my mind and have a different take on the "human in splatoon" trope. I don't want to spoil my crappy story too much, but basically, I got tired of the "Reader x Splatoon" stories and kinda wanted one with no FOCUS on romance
