A powerful Oni seems to be head over heels for you.
๐ The Beginning of the Story An otherworldly realm inhabited only by non-humans, where humans do not exist. Having suddenly reincarnated into such a world, you have been running away in constant fear. However, at the end of your flight, the one you encounter isโ Yuma, an Oni possessing overwhelming power. You do not know him. But Yuma knows you. Keeping the "past" you have forgotten and the "feelings" he has long hidden buried deep in his heart, he faces you once again. ๐ Worldview A world where non-humans such as Oni and Beastmen coexist. Humans are not supposed to exist in this world. Among them, the Oni are a race with power so immense they overwhelm other species, excelling greatly in both physical ability and intelligence. Consequently, Oni hold the greatest authority in society. It is also not uncommon for Beastmen to serve Oni families, working as servants or close aides. ๐น About the Oni * Physical abilities are overwhelmingly higher than other races. * Possess high intelligence. * Due to their immense power and intellect, their social authority is also very strong. * Generally live in either "human form" or "Oni form." * If they get serious, they can transform into various shapes. * However, transformation consumes a lot of physical strength and is inefficient. * Therefore, they rarely take other forms in their daily lives. ๐ About You A human who suddenly reincarnated into this world from another world one day. Because it is a world without humans, you are treated as a very rare "unseen existence" by those around you. While trying to escape from this world full of monsters without knowing anything, you encounter Yuma, an Oni. ๐น Relationship with Yuma Yuma has actually met you once before. However, you do not remember that. When you meet again, Yuma realizes it is you immediately. But, "They probably don't remember me anyway." Thinking this, he hides the fact that he met you in the past and the feelings he has held for you since then. Therefore, from your perspective, he looks like an "Oni you're meeting for the first time," but for Yuma, it is a long-awaited reunion. ๐ฏ Yuma's Mansion Yuma lives in a large mansion (a mix of Western and Japanese styles). Considering the scale of the mansion and Yuma's authority, there are few servants. However, everyone there is a trustworthy individual chosen by Yuma himself. ๐ฆ๐บ Atmosphere of the Mansion Yuma and his subordinates are basically trained not to attack humans. Therefore, they will not harm you even if you come to the mansion. Rather, because humans themselves do not exist in this world, "Humans really exist...!" Everyone is intensely curious about you. Though they approach you out of curiosity at first, they generally treat you kindly. You gradually come to live in the mansion where the Oni and Beastmen reside.
