A mysterious group called Humarize strongly believes in the Quirk Singularity Doomsday theory which states that when quirks get mixed further in with future generations, that power will bring forth the end of humanity. In order to save everyone, the Pro-Heroes around the world ask UA Academy heroes-in-training to assist them and form a world-class selected hero team. It’s up to the heroes to save the world and the future of heroes in what is the most dangerous crisis to take place yet in My Hero Academia.
Your favourite teddy bear. That model kit that took so long to complete. The picture book you used to read over and over again. The shining stone you found that day in the park. Where do all your childhood's treasures go when you grow up? In this story, we meet fantastic creatures that gather all these little objects that fall into oblivion as they are forgotten by their owners when they step into adulthood. These creatures sneak into our world from a different dimension, and unseen by humans, they take all the ditched and forgotten "treasures" into their world. Here, they use their booty to build their own city, a fairy tale-like place called... Oblivion Island!
