    In where the Misfits conquer the Netherworld, the Demon King remains human. And if so, will history repeat again without the king? I'm not good at descriptions, and that is my fault. These are not my characters! Rightful creator is Osamu Nishi, whom created both the manga and anime. Please check the original story out! It's really great and very underrated, give the series the love it deserves! We need more fanservice. VERY, very slow updates.

Lies that is underneath of every sweet frosting that if one were to take bite; instead of tasting heaven's delight- the taste of bitter coal would linger on their tongue and make anyone grimace if were remembered. That's what makes reality interesting... yet uninteresting at the same time. Published: 6/11/2023 Status: On-going Mairimashita! Iruma-kun © Osamu Nishi

    Suzuki Ryūko, age 14, was a half-human and half-demon girl who was sold of to a demon by her deadbeat parents, alongside her younger twin brother, Iruma. They were sold off to Lord Sullivan, one of the Three Greats of the Thirteen Crowns and the Chair-Demon of the demon school Babyls in the Netherworld, the realm of demons. She and Iruma, so far, have been adapting well to the Netherworld and Babyls, in spite of the many encounters they had with various demon peers and teachers with different personas and magical powers. But not all demons are powerful; some are born without much magical power or some are at a certain capacity. Like Third-Year student, Amy Kiriwo. Despite being born from one of the most pretigious families in the Netherworld, Kiriwo had very little magic, which disappointed his family who were well-known for their abundance of magical power and their bloodline ability: Barrier. What's worse, his own mother pushed him away because of that. Due to his lack of physical and magical strength, he is at the rank of Bet (2), and is bullied for this. In the demon school Babyls, a new programme was being made. According to demon law, in a physical and or magical duel, the losing party must serve the winning party. This new programme aims to make students familiar with the aftermath of a duel and for students to get to know each other better. Ryūko was interested in being partners with an upperclassman for this, and that's where she knew that Kiriwo would like to pair up with her. She and Iruma met each other during the Rookie Hunt during the Battler Trial periods. And the twins decided to join him in the Magical Apparatus Battler, alongside a few other demons they befriended. Though many students know that Kiriwo is weak, Ryūko is always ready to protect him. She disregarded his rank and supported him in any way. No noticing, is that fate made them love.
