Lord of the Nightmare Sword

The Hundred Years' War has ended. Technology has stagnated, while martial arts have flourished, and the strongest martial artists command the world's respect.

An unremarkable, frustrated boy accidentally enters a wondrous dream and gains countless sword techniques and combat skills he has never heard of before. From then on, he sets out to become a powerful martial artist.

Snake Bite, Sharp Claw, Eightfold Buzz... combo sword skills from Sword Art Online.

Gorilla, Lion's Song, Thirty-Six Prower... the domineering swordsmanship of the great swordsman Roronoa Zoro.

The Six Powers, Life Return, Haki... the limit-breaking martial arts of CP9's strongest member, Rob Lucci.

When these formidable martial arts, obtained in a dream, appear in another world where martial arts thrive, what kind of turmoil will they unleash?

This is the story of a boy who gains power from a nightmare and goes on to rule the world.
