Summary
Iruma has been feeling odd lately.
It didn't feel like any ordinary ailment, but it was clear that he was seeing things. A shadow, out of the corner of his eye. One that when he stared, it stared back.
One that no one else could see except for him.

Summary
Iruma kicks off from the wardrobe with such force it rocks back, almost toppling over, and soars across the room. He lands on his new nest with an explosion of blankets and feathers, growling low in his throat whenever his claws get caught in the fabric.
There’s no way these humans will let him stay after they realise what a useless demon Iruma is. But tonight he has a new den and a full stomach and clean skin and, for now, that is everything.
(Species Swap AU: Iruma’s first night in the human realm.)

Summary
Iruma is hired as a teacher by his grandfather. It was to create an opportunity for Iruma to gain teaching experience and other learning points, that his current position in the school would not bring him. Discreetly, this was actually part of Sullivan's preparation for him to become the next Demon King. The Demon King, as who knew everyone and managed absolutely everything in the netherworld, down to even the smallest details.
“The Demon King is the netherworld itself.” Sullivan had once told Iruma. That was when Iruma came to the realisation that the Demon King was everything. Well... A teacher was another thing. Prioritising the students' safety above anything, even going as far as to sacrifice yourself, was one of the duties of being a teacher. An Evidol was another thing. Lastly, grading papers, don't get me started on that one..
Iruma-sensei is also faced with challenges as an Evidol! As much as he finds it embarrassing, refusing his students' requests seem almost impossible.
“Please, Iruma-sensei. This is really important! I need to win this! Please!" Kerori, the Evidol, Kuromu, begged.
“… Alright, alright.” Iruma gave in. In the end, not even Iruma-sensei could resist the very word, “please".

Summary
"Iruma remembered turning the corner to reach the Royal One, when a voice he hadn't heard in months came from behind him. "Iruma-chan~" His skin crawled. Iruma recognized that voice. He hadn't heard it since the Heartbreaker event. Iruma turned around and what he saw confirmed his doubts: Atori, the teacher who had gone mad during Heartbreaker and attacked some students and other teachers, was standing there as if nothing had happened. A creepy wide smile on his face, the demon was looking at him slyly "How long! How about a reunion with your teacher?" Atori asked mockingly"
Basically Iruma is kidnapped by the Six Fingers and they try to convince him that he is a patient in a psychiatric clinic.

When Iruma’s eyelids closed on consciousness, they opened to a nightmare. It was a scene he had grown familiar with, from seeing it over and over again each night since the Deviculum. The dream always started the same; in an empty, cold void. Soon enough, his senpai would appear before him, like he had that night. The demon's overwhelming presence was Iruma's prison.
Iruma's meeting with Kirio at the Deviculum takes an unexpected toll on his mind, and he struggles to adapt to normal life at Babyls again.

Summary
Offsprings from the succubus race usually tend to be female, but there is an extremely rare case for them to be born male. They typically fall to be just normal demons, like the majority of the population of the Netherworld. However, there’s an abnormal case where they inherit succubus traits.
Meet Asmodeus Alice, he is one of the minorities who is born male in a succubus lineage. Initially, he thought he didn’t inherit any succubus traits. No heart-tipped tail, No pheromones, and definitely never bloomed to experience a heat cycle that usually starts during the teenage years of a succubus…Right?
…Right?
Wrong! This story revolves around Asmodeus Alice experiencing his first-ever heat cycle during his adulthood with his partners.
