YASHAKIDEN DEMON PRINCESS NOVEL (2025)

"After a devastating earthquake that left most of Japan in ruins, the district ward of Shinjuku in Tokyo has opened up a doorway into another dimension-becoming the halfway-house suspended between the mortal world and the supernatural. Coming from the deepest and darkest parts of China, four immortal vampires, led by one of unmatched beauty and who goes by the ubiquitous title 'Princess,' mystically sail into landlocked Shinjuku aboard an ancient ghost ship one roiling hot night. She and her ancient undead entourage with powers never before seen of vampires, have surmounted four thousand years of space and time to seize control of Shinjuku and make it their own. Can two humans, Setsura and Mephisto, stop them before they plunge the living populace into a new level of fear and slavery none can escape?"

"A vicious vampire gang four thousand years in the making has awakened from its slumber in order to seize control of Demon City Shinjuku. Princess, Kikiou, Ryuuki and Shuuran are as persistent as they are merciless, especially when the target of their attacks is Setsura Aki. A treacherous house of reptiles built of giant leeches and poisonous snakes-Ryuuki's ghost koto 'Silent Night' and his malevolent demon qi-Shinjuku's heavily armed police becoming vampires and attacking its own citizens- Demon City is transforming into Vampire City before their very eyes. To make matter worse, despite his wizardly powers, Setsura is assaulted by Shuuran and is turning himself. His trusted friend and colleague, Doctor Mephisto, shows ominous signs of becoming a slave to their wills. Setsura has never before experienced such dangers in his life!"

"The immortal vampire gang led by 'Princess'-Kikiou, Ryuuki and Shuuran-is slowly but inexorably taking over Demon City Shinjuku. Its citizens and the administration alike are turning into vampires. Mephisto has apparently allied himself with them of his own accord. Setsura Aki stands alone on the brink of extinction, tested by one desperate counterattack after the next. Intending to snuff out his life once and for all, Princess unleashes the self-regenerating Kazikli Bey (better known abroad as Vlad the Impaler, the original Dracula). Meanwhile, concerned about the worsening state of affairs in Shinjuku, a team of foreign legionnaires-Special Forces Operational Detachment 'F'-is dispatched to Demon City. This Medusa of a supernatural face-off has grown another head. The confusion deepens and Shinjuku's fate hangs in the balance. But what is Mephisto really up to?"

"Writer Hideyuki Kikuchi, Artist Jun Suemi As the immortal Demon Princess inexorably transforms Demon City Shinjuku into a vampire metropolis, Setsura infiltrates her manor house alone. There he encounters the puppet paramours and 'picture soldiers' created by the warlock Kikiou. The witch Galeen Nuvenberg once again comes to the rescue.
