"If he cannot stop it either, then the Wyvern of the Sea would sink this continent to the ocean floor." Roy Excindo was supposed to be an anime otaku, hikikomori, and just an averagely smart Grade 10 student. But somehow he ended up here, in Argentum Slimona, and started to fight for the people he called friends, as well as Outerworlders that were only supposed to exist in stories. And now he has taken out a Devil Lieutenant, a race 15 ranks higher than his own on a chart dictated by gods. The next step of his journey was supposed to go to the Twinprint Archipelago to train, where many others like him do the same. In order to prepare for the fight in the tournament taking place in the capital, Roy sets off towards the seaside! But hidden dangers and ascertain events lie ahead. Roy struggles to decide his destiny, but it all comes crashing down due to an assassin, a devil, a Wyvern, and... a god.

"Have you, ever been isekai'ed?" Roy Excindo, a normal student, otaku, and half-shut-in decides to go and confess to his crush on a whim, but instead falls into a sewer lid and was reincarnated in his original body in a different world, one where forces similar to earth exist while also having a magic force known as manaki. However, Roy's journey was cut short on his first attempt to walk, when a wolf decided to kill him for food. That's when Roy realized his journey was not going to be easy. "No way... you are..." "Could it be, that I'm not the only one?" In the mysterious journey, Roy finds his purpose in life, and decides to help out all others like him, whether they were supposed to be fictional or not. Powers that are unique just might save them all. The craziest isekai that connects a megaverse is about to unfold!
