His Shadow. (An MHO AU story)

In this world, 80% of the population gets what we like to call a 'Quirk.' If you don't already know, a quirk is like a superpower you get once you hit a certain age, and everyone's is different. This story, although, follows a certain boy named Artemis, with a very...unique quirk per-say. There is a lot people have yet to learn about his abilities and power, and a lot for him to learn about it as well. His quirk allows him to control and create shadows, as well as giving him two...companions we'll say, Umbra and Soren. One thing Artemis has to find out the hard way is that his quirk has a big consequence to having such great power. How will he learn to cope with what life has decided for him? How will he learn to control his abilities?
