High School DxD : The Melancholy of Nagatobimaru
After his final battle against Hakumen no Mono, the ancient yokai Tora awakens in a world that feels strange.
The war is over. His partner, Ushio Aotsuki, is gone. The Beast Spear has vanished. And the world he once knew… no longer exists.
Now stranded in an unfamiliar land governed by devils, angels, and powers he neither understands nor cares, Tora roams aimlessly, searching not out of hope—but because something that should be there… isn’t.
Until he arrived in quiet city of Kuoh.
But beneath the surface of the modern city of Kuoh, something far older stirs.
Long ago, a fallen samurai named Kagenori gave his life to protect his people. Worshipped as a guardian deity, he became the will of the town itself. For centuries, he bore the weight of misfortune, disease, and despair in silence.
Until the burden broke him.
Corrupted by war, forgotten by those he protected, and consumed by the endless accumulation of human suffering, the once-revered guardian has become a curse—an unseen force that feeds on the very life of the city to sustain itself.
And at the center of it all… is a single child.
Ushio Okazaki—a fragile girl whose existence is mysteriously bound to the soul of the town. Unknowingly, she is being drained by the very entity that once saved her mother, Nagisa Furukawa, in a desperate attempt to preserve its own sanity.
To the world, it is nothing more than misfortune.
To Tora… it is something else entirely.
Because this time, the thing devouring Ushio is not a monster driven by hunger—
but a protector that never learned when to stop.
And for the first time since the end of his war, Tora finds something worth tearing apart again.
