    Summary

    Iruma has worked as many things.

    An errand boy, a cashier, a janitor, a waiter..

     
    But one of them stuck out to him the most. 

     

    Well..bartending.

     
    not at a bar or a pub, but a nightclub.

     
    It sounds simple on paper, right? Just memorize how to make a few drinks, then make them for the customers and repeat, repeat, repeat and repeat until your shift ends. Well, it was just like that..but more different for iruma.

    And with that memory coming back, a bunch more did.

    Summary

    They say the Demon King vanished without a trace.

    No one knows why.

    No one knows where.

    So why… does Rin Maouka feel like the answer is looking back at him?

    Reincarnated into the Netherworld with a power that distorts reality itself, Rin is thrown into a world where strength defines everything and weakness gets erased.

    But the deeper he goes, the clearer it becomes:

    His existence isn’t normal.

    It isn’t natural.

    And some demons… already know it.

    Summary

    A lot happens on Iruma's first day of school. He makes new friends, meets a few teachers, wins a notebook in a small challenge a teacher prepared, and he finds out what class he's in!

    It's an exciting ride, and from there, Iruma has what he needs to start building a small support system, the first one he has ever had. It should only be small though, it's not like he's super-duper likeable. Right? Right??

    Summary

    Уявимо, що було б, якби Ірума продали Кальєго, а не до лорда Саллівана через своїх родичів, що захотіли собі спадщину і заразом позбутися "білої ворони" сім'ї. Але ніхто не знав, що в гонитві за грошима вони з'єднають справжню сім'ю

    Або історія про те, як сторожовий пес виховував людську дівчинку і виявився з нею зв'язаний, тож прийняв як доньку та хоче, щоб вона стала наступним сторожовим псом школи. Але з цього часу вийде ціла пригода

    Summary

    Iruma’s eyes inadvertently catch sight of the mirror on the side of the wall in front of him. His blood freezes and eyes widened as he caught sight of a large silhouette looming right behind him. Tall and slender, height that would have had the large horns on its head hitting the ceiling. Large, looming, and long hair spread out like an unholy halo. 

    He blinks and it's gone.

    Then he falls—down and down into the darkness.

    _________________________________________________

     

    Iruma has a soulmate he doesn't know and it comes to haunt him—literally. Now he has to traverse the Netherworld hiding his human identity, get pulled into schemes years into making, study to pass Babyls, and try to figure out just who is his sleep paralysis demon and how can he kindly ask them to stop terrorizing him.

    Summary

    Once upon a time, there was a boy who shone so bright that he lit up the world and changed everything. But this is not his story. This is the story of the events behind the curtains, the eyes that see the changes he brings with every step. The secrets, the lies, the conflicts, and the sins. This is the fairy tales of the wicked and the damned.

    Snippets, different POVs, and behind the scenes of the main story, 'Tell Me—Can you see me?'.

    Summary

    “Snap!” Clara cheered, slamming her cards dramatically into the centre of the pile.

    Everyone stared at the cards in silence for a moment before Crocell spoke up shyly. “Um, I thought we were playing Chase the Nine?”

    “We were,” Lied replied slowly, quickly glancing at his own cards and back at the ones Clara had just placed on the table “That doesn’t even make sense” he comments again.
     
    “Clara, you can’t just invent rules!” Asmodeus snapped. “That’s not how the game works”.
     
    A trip to the Grand Bablys hotel started off all fun and wholesome for Iruma and his friends, but after just one night staying there they were now trapped indoors due to a weird anomaly. As time progresses Iruma begins to notice his classmates slowly starting to act weird, and not the type of weird they usually are. Not to mention the peculiar receptionist downstairs, somethings not adding up here, and Iruma hopes his friends are ok.

    Summary

    Despite the fact that it was a throw away line, he couldn’t get it out of his head. "Papa Balam."

    Being a father felt like the natural progression of his love for living creatures and cultivating life. One day, that life would be partially made up of him. But it would be better than that, because they would grow into their own person too. It’s part of what makes life so beautiful and precious. The problem wasn’t that he didn’t want kids.

    The problem is that he is in no way ready now. So yes, the comment was said in jest but it shook something in him.

    Or

    Balam hears some of the misfits joke about him being their dad and he panics only slightly.

    Agares odiaba muchas cosas, bastantes a decir verdad no podría nombrarlas todas, pero lo que si podía hacer era una lista con las cosas que más le molestan.

    —Que no lo dejen dormir
    —Levantarse temprano
    —Personas ruidosas
    —Que lo molesten cuando duerme

    Pero últimamente hay algo o mejor dicho alguien que se estaba ganando un lugar en esa lista.
