Call me Shinobi-sama!

Akira Minato, known as the King of the Shinobi in Ancient Japan, was a fearsome legend who brought terror to daimyō and demons. He achieved impossible feats, from single-handedly defeating thousands of samurai to destroying demon temples and shoguns. His reign of terror ended unexpectedly when, during a pursuit of a mysterious treasure, he encountered an Ultimate Oni. Forced into a supposed "glorious sacrifice," Akira sealed the Oni with his soul, only to awaken centuries later in 2025 Tokyo. He finds himself in a teenage body, clad in cat-print pajamas, his formidable powers sealed. Monsters, now more aggressive than ever, plague Japan, prompting the formation of JINKOKU, the Monster Hunting Authority. With no powers or resources, Akira is compelled to become a registered monster hunter. His mission is to regain his lost strength, find a path back to his own time, and perhaps win the affection of Princess Yuki, a woman bearing an uncanny resemblance to someone he failed to save. Once a supreme warrior, Akira is now underpaid and deeply in love with the Princess. Despite his altered circumstances, his legendary status as Shinobi-sama endures.
