Yuna Kato is an advanced model belonging to a popular spiritual group. Summoners, chosen by the gods, people believe their purpose is to keep the peace in both spirit world and on earth. The thing most people aren't aware of though, is that most Summoners were only children, taken from their homes, and forced to train under straining conditions. Usually conditions that only allowed the strongest both mentally and physically to survive. They were taken to camps, and taught different techniques, curses, spells, and most importantly, how to summon. The ability to call spiritual beings for assistance. Yuna was one of these children, taken away at a young age. The difference is, she showed much promise, so much in fact, that she grew haughty and confident in her abilities, choosing to leave the academy through force she traveled alone through the land, using her power for her own worth. This was illegal, and she was branded as wanted by King Yama. She was eventually captured and brought in, installed back into the regime with the rest of her companions, summoners. Her memory wiped, her mind returned to a tender child-like state. Two years later, when a choice was given to Yusuke, to choose a summoner as an assistant in his occupation, he chose none other than Yuna.
Y/N Ōtā was a unique child. She had lovely parents, grandparents, and two older siblings. Her mother had a healing quirk, and her father had a water quirk, and both were powerful, strong, amazing heroes. Though, she was the only Ōtā who got a combination of the two quirks, making her a very promising candidate for the hero business. Truly destined for greatness.
But, you can't have a determined hero without some life-lasting trauma, right?
When Y/N and her family moved to Japan to live with her grandparents for five years, her mother and older brother were murdered by a dastardly set of crazies who called themselves the "League of Villains." Later, Y/N's father, and older sister, were also killed by the same set of villains. On top of that, she is accepted into the greatest hero academy in Japan - U.A. High School. It was what her parents and siblings would've wanted - that is, if she hadn't desperately accepted help from the League of Villains when she was fatally wounded.
When Y/N finally escapes the restricting clutches of the League of Villains, she must piece her life back together by earning her spot back in the Hero course, proving her loyalty to the heroes over and over again, and living up to the Ōtā name.
What she didn't want - or expect - to do was fall in love.
