    Iruma was an actual demon, he didn't have a tail or a horn and he lived in the human world for almost his whole life. He never questioned anything about himself, all he knows is that he had "parents" who left him anywhere to fend for himself and that he was not like any other child. His whole life he believed he was human, but he always felt something hurting his back. He doesn't remember himself getting scars as he mostly evades every danger he faces. It was already something that came to him naturally, his instincts per se Now suddenly being adopted and going to school in the netherworld. He thought he was still human until a sudden teacher who's popular for "experimenting" on students touched his back and immediately rushed him to the teacher's faculty room.

It's been almost 13 years since the adoption and they live a normal life as nepobabies. It was July, and the 6 fingers were threatening (again) the government. It was nothing very important for them since they're teenagers and don't really care about anything, except that this little threat would benefit only one of the three siblings and affect horribly the other two. ♔︎♕︎♔︎ 𝑺𝒐𝒎𝒆𝒅𝒂𝒚, 𝒂 𝑲𝒊𝒏𝒈 𝒎𝒖𝒔𝒕 𝒓𝒊𝒔𝒆, 𝒂𝒏𝒅 𝒕𝒘𝒐 𝒌𝒊𝒅𝒔 𝒎𝒖𝒔𝒕 𝒇𝒂𝒍𝒍 𝒔𝒐 𝑯𝒆 𝒄𝒂𝒏 𝒄𝒐𝒎𝒑𝒍𝒆𝒕𝒆 𝑯𝒊𝒔 𝒑𝒓𝒆𝒔𝒄𝒓𝒊𝒃𝒆𝒅 𝒅𝒆𝒔𝒕𝒊𝒏𝒚. ♔︎♕︎♔︎

    Excerpt from: Demons of the Netherworld, chapter 18 - Cambions "...A Cambion is a mythical creature commonly found in European mythology and literature. It is the result of the union between a demon and a human. The power of a Cambion relies on the power of the demon's lineage. However, some cases show that having Human blood can strengthen a Cambion's power. Similarly to high-level Succubi, Cambions lure mortals to the Netherworld. They are far less common, however, due to the fact that Demons would rather eat a human than mate with it, as Human flesh and blood is commonly known to be incredibly nourishing- not to mention tasty. Because of this, Cambions have essentially faded out of the Demonic Hierarchy of today. Because of their Demonic blood, Cambions are generally ostracized from Human society because of inherited Demonic traits: Horns, Tails, Claws- some may even experience Evil Cycles, depending on the potency of Demonic blood. However, some Cambions may also have other non-humanoid aspects- Unnatural Hair Color, Fangs, Unusual Pupils, etc...." Hello! I've decided that Welcome to Demon High School, Iruma-Kun! needs more fanfiction, so here I am! This will be my first ever published fanfiction, so please excuse me if the writing seems off, the story is paced weirdly, or the characters are OOC. I DO NOT OWN WELCOME TO DEMON HIGHSCHOOL IRUMA-KUN. THIS IS FOR MY OWN PERSONAL ENJOYMENT. I OWN MY OC, CORDELIA, AND THE ORIGINAL PLOT POINTS I COME UP WITH.
