Summary
Saiki Kusuo and PK Academy was swept up into the Petrification, same as the rest of the world. But, Saiki, being the strongest psychic in the world, was actually able to meet the Medusa's goal of having a human think themselves out of the rock, without use of nitric acid.
It just took him thirty seven hundred years to manage it. Right before Ishigami Senku did the same with a little leg up from the old miracle liquid.
And he wasn't the only student of PK Academy to have been revived in the Stone World, either. -

Summary
Saiki Kazuo is the son of the most powerful psychic (Saiki Kusuo) and the self-proclaimed most beautiful woman on earth (Saiki Kokomi). Blessed with his mother's beauty, but without his father's power, He loathes his life. Yet he is not the main character of this story.
Sato Nekomata is a cursed girl. By God or evil, she cannot tell. Every supernatural ability ever written lives within her. She is a ball of destruction waiting to explode. (Literally, she can do that and reform.) After accidentally splitting her school in half (don't worry, she repaired it), she is forced to move and attend PK Academy in Japan. It's only when she meets a pompous purple-haired boy that she realizes she might not be the only one with supernatural abilities.

Summary
Saiki never thought there would be any issues with rewinding time. Everyone should be oblivious to the loop. His mind control meant to ensure that it went unnoticed by everyone else. Now that he has finally stopped the volcanic eruption, allowing the loop to end should have been inconsequential.
But Saiki could never have expected another 17-year-old cities away to question the small hints left here and there that his mind control couldn't prevent. Nor could he have planned for this other teen to be the right-hand man of an entire mafia.

This is half fanfiction, half biology slideshow. It will make your brain hurt if you don't know any of this stuff. There's almost no plot.
(hopefully this helps me learn stuff)
