The story takes place in a world where Japan never ended their isolationist phase, and agents from foreign powers are always threatening to steal the country's advanced technology. In order to combat this threat there has been a resurgence of ninjas that use Strategic Martial Arts, techniques that combine cutting-edge modern technology with a traditional foundation of martial arts and ninjutsu. The story follows Souha Sugiyado, a 17-year old ninja instructor and former ninja prodigy who was forced to retire from active duty by the wounds he suffered in his last mission. Souha's four students are all kunoichi who have all gained the rank of Elite Ninja, the highest official rank available to ninja. However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

「Shimizu-san, you dyed your hair black.」「Ah, yes.」「Why did you dye it all of a sudden?」「Because…yesterday…」Shimizu-san, who sat next to me and had dyed her hair from blonde to black gradually lowered her voice, slightly blushed, and laid her face down on the desk.

I love you, Brys,” he repeated as he leaned closer to kiss me. “I've had feelings for—”The words died on his lips. His eyes grew wide in shock as blood spluttered from his lips. “Wh...

I have calculated for people before I was born, and I have all five yin, and I am born with fierce ghosts. A knowledgeable gentleman said that I will not live to be seven years old. After death, I will cultivate blood-clothed little ghosts to harm people.

In order to save me, my grandmother married me a child-in-law, so that I had an Ann birthday, although I later discovered that the daughter-in-law and sister-in-law are not human…

I have been lingering and panting since I was a child, and I have been accustomed to accepting it, but my grandmother was killed.

For this reason, regardless of karma, I inherited my grandmother’s job of raising ghosts and vowed to send everyone who killed her to hell.
