The 1920s was a decade of great change and upheaval, with monstrous demons appearing across America. To combat this menace, the holy organization known as the Order of Magdalene was established. The organization's New York branch is home to the young and reckless Sister Rosette Christopher, as well as her partner Chrno. Tasked with the extermination of demonic threats, the renowned team is excellent at their job, despite causing extensive collateral damage on their missions. However, both Rosette and Chrno are driven by their dark pasts. Through exterminating demons, Rosette hopes to find her lost brother Joshua who was taken by the sinner and demon, Aion, with whom Chrno also shares a bloody history. The two of them must fight off the increasingly dangerous demonic menace and discover its source, while continuing to search for the truth behind Joshua's disappearance.

Koushi Inuzuka is a smart high school student who aims to become a public prosecutor. Unfortunately for our good guy, he was born into a martial arts family whose head (ie his father) only knows one language: violence. When Koushi was still a baby, his father made a pact with his biggest rival to marry Koushi to his opponent-turned-friend's daughter. The union of the two blood lines is supposed to bring forth Earth's strongest martial arts clan. Skip forward: Koushi is in high school, oblivious to the marriage arranged for him at his birth. Enter Momoko Kuzuryuu: sugar bomb, airhead, loli martial arts artist and Koushi's self-proclaimed bride (the strongest on Earth, no less). Her wish for sexual intercourse meets with Koushi's square refusal as he has absolutely no desire to get it on with someone who looks like she could be his little sister, not to mention that he doesn't have the foggiest idea who she actually is. Meanwhile, a war has broken out between the martial arts families. For Koushi, this means that numerous fighters are out to challenge/assassinate him. As if that weren't bad enough, our protagonist also has a fight phobia due to a traumatic incident that took place in his childhood. Now it's up to Momoko and her superhuman fighting skills to protect her "husband." Will the two sweethearts survive the trials and tribulations ahead of them? More importantly, will Momoko get her way receiving a baby from Koushi? (Source: Kotonoha)
