Nukenin from Hell

In the war with the newly resurgent Demon Realm, there have been victories and there have been defeats. One such defeat came in the Yokoshima Archipelago, where the Yōma Union and its allies in the Demon King's Army overran the human beachhead of Hijirijima. For those left trapped behind enemy lines, they had two choice: to fight and die or to submit and live. Many who would have chosen the former could not follow through on their resolve once the Demons found the right leverage to use against them. So it was for the little family of Yasuko Suzuki Rodrigues. For the past two years, they have grudgingly helped the Demon King's servants secure their hold on Yokoshima as a staging ground for attacks on the Continent. Yasuko herself has had to go from Yōkai hunter in training to the personal assassin of the ambitious Demon officer Sturla Grimason. However, as the Valerians prepare a new assault to retake Hijirijima, Yasuko sees her chance to defect, but can she save her family and put down her hated foe, all while his minions are hunting her?
