    Summary

    To think that decades of hard work, of countless sacrifices, all done in the name of unity, could be undone in just a single night; and by a group of exwires- teenagers, no less.

    No matter. Lucifer is more than willing to pick up the pieces. This wasn't a loss per se. No, not in the grand scheme of things. It was all just a small hiccup, and the fallen prince had spent far too many centuries- nay- milennia for his operations to fail.

    All that needs to be done now was a simple change of strategies. With the pieces now in place, the king of light makes his move to dispose of the True Cross Order's most precious Knight...

    Through marriage?!

    Summary

    Pale lips moved on the butler’s frozen face, but Iruma didn’t hear a sound. Opera gave his master a cold, catlike gaze, his sharp eyes glittering faintly, then suddenly leaned in, fixed Iruma’s slightly crooked red tie, and stepped back. Suzuki froze in shock: his heart clenched with burning pain, then thumped abruptly, swelled, grew heavy, and began beating faster and faster. His palms broke into a cold sweat and shook with treacherous tremors.

    Summary

    "The fact that a human like Iruma had shown omega-like characteristics left all the residents of Sullivan Mansion surprised and speechless. Outside, however, the demonstration of the first omega-like characteristics was greeted without particular concern. This could be due to many causes, including prolonged exposure to the Netherworld environment after more than a year of living there. Iruma explained to a desperate, tearful Sullivan and an Opera with their feline ears and tail raised, that humans did not have secondary genders like demons. Had the mutation begun and ended there? The two adults wondered, while Iruma waited patiently for explanations about what having a secondary gender, and being an omega above all, entailed"

    Basically Iruma has become an omega and discovers what it means to be an human omega with an demon alpha as a partner.

    Summary

    Due to an incident in Japan, Iruma had been forced to spend a majority of his life in the area around an odd city known as Danville.

     

    It was.... well honestly he actually found himself enjoying the people there far more than his own parents.

     

    He even made friends with some nice kids over the summer, and found mentorship in a nice evil scientist and his platypus nemesis.

     

    But all good things had to come to an end, and his parents sold his soul for money.

     

    To bad for everyone you can take a boy out of Danville but you can't take the Danville out of the boy.

    Summary

    Even though Eiko always tries, but for Iruma-san and Ameri-san she never had the right opportunity to meet and talk to them directly and correctly.

    But as for Asmodeus-kun? Eiko has plenty of opportunities for that.

    And honestly, it wouldn't hurt Eiko to try, this year is her last and if it doesn't work out, Asmodeus-kun and herself wouldn't have many chances to meet each other after graduating from Babyls Academy.

    They might just grow apart and never be as close as they are now. But rather than Eiko regretting not trying, it's better for her to regret having tried, because what makes a devil great is a strong desire for success! Or just strong desire for anything.

    Summary

    In the Netherworld, three Naberius cousins are walking home from an ice cream parlor and run into a horse drawn hearse. Waking up in coffins at a college ceremony was not the punchline to that joke.

    Yuna Naberius - Playful, mischievous, confident, charismatic, slightly sadistic, shocking and the most energetic with a thirst for chaos and justice.

    Zephyrine Naberius - Tactful, strategic, calm, stoic, curt, business, strict, protective, cold woman with a hot temper as she is the only adult in the room.

    Violina Naberius - Quiet, shy, meek, reasonable, understanding, anxious, sweet, kind, compassionate, empathetic, serves as the mediator whenever her cousins clash.

    Three completely different personalities serving as a single powerful unit as Guard Dogs of the Netherworld, have now come become students at Night Raven College. What could go wrong?
