Tougen Anki

Long ago, demon-like creatures known as Oni brought terror and destruction upon humanity. A legendary warrior named Momotarou rose to challenge these formidable beings, beginning an ancient conflict between humans and monsters. In the present day, Shiki Ichinose lives as an ordinary high school student with a passion for firearms. His peaceful life takes a dramatic turn when he discovers that he possesses a mysterious connection to the Oni - a revelation that thrusts him into a hidden world where ancient bloodlines still clash. As Shiki grapples with this newfound heritage and the awakening of powers he never knew he possessed, he finds himself at the center of a conflict that has spanned millennia. With the guidance of those who understand the true nature of his abilities, Shiki must navigate between his human life and the darker legacy flowing through his veins. At Rasetsu Academy, a special institution for those touched by the supernatural, he begins to uncover the secrets of his past while learning to master the dangerous power that lies dormant within him.
