My Hero Academia: Spiritual |Book one|

Long ago, before everyone had quirks, the spiritual world and the human world used to coexist together, living in harmony. That was until Maria, their top guard in the spiritual world, wanted the spirits to take over and dominate the humans. Maria told the King and Queen the plan of a lifetime only to argue and yell at them for not only not liking it but calling her stupid and ignorant for even thinking of it. The king yelled at her to leave and never bring up this topic ever again. And if she ever brought it up again, she'll be stripped of her title and pride. Secretly, she grouped up a bunch of soldiers who wanted the same thing as her and caused chaos in the human world, whispering about what the spirits whisper behind their backs, nothing but awful and untrue words. But it did the job and got the humans angry, even the king and queen. The war started between the humans and spirits, but just as the war started, it ended just like that. Two dragons, the yin and yang, separating the humans and spirits. And that is how they were born...... . . . It's been 999 years since then, and the Yang dragon was gone....A crack in the between worlds...
