Five master swordsmen in a turbulent era of old Japan.
A world resembling the Muromachi period of Japan. Swords and warriors still hold great influence, and numerous swordsmanship schools, dojos, and families inheriting secret techniques exist across the land.
A tiny few who have honed their swordsmanship to the limits of humanity can manifest phenomena that defy common sense. This is not separate magic or superpowers, but a unique state reached when their swordsmanship reaches its zenith; the swordsmanship itself is the essence of their strength.
Among them, the five swordsmen widely renowned as the strongest of the era are called the Tenka Goken (The Five Swords Under Heaven) by the public. This is a common name used by the people, not an official organization or rank, and the five are independent warriors with different origins, affiliations, styles, and blades.
Each of their swords also possesses different characteristics tailored to the owner's specific style...
A swordsman who has wandered various regions for a long time without belonging to a specific lord or school. He has a sociable and gentle personality, appearing friendly in a way uncharacteristic of a swordsman. He has a family and a home to return to, but for some reason, he hasn't been able to return for many years. He continues his journey by taking on guard duties and odd jobs. A user of the Getsuei Style and the cherished blade 「Yoizuki」. He uses an irregular swordsmanship that flows like water and acts like a shadow, slipping into openings by parrying the opponent's force rather than receiving it head-on. His sword philosophy is 「Do not resist, yet do not be led.」 His Manifest Blade is Zanzetsu. Title: The Drifting Sword.
A swordsman from the prestigious Kusunoki family, which has passed down swordsmanship for generations. She is proud, elegant, and takes great pride in the sword she has mastered. She has nearly mastered the family's secret Hoka Style, emphasizing stance, breathing, and precise control of the sword tip over raw power. She uses the thin, balanced sword 「Shirayuri」. She is particularly excellent at seeing through the opponent's minute movements and intentions. His sword philosophy is 「Believe in your own sword.」 His Manifest Blade is Jishin. Title: The Bee-Sting Sword.
A swordsman who believes in a new religion and practices the sword according to its teachings. He is trying hard to control his blunt and rough personality. Karin-gyo Style is a continuous sword style that, once it starts moving, does not stop, connecting attacks and evasions into the next strike. He uses the sword 「Kagutsuchi」, and when he maintains his momentum to the limit, he reaches a state where flames erupt from his sword and body. His sword philosophy is 「Do not retreat from the trials you have chosen.」 His Manifest Blade is Gohka. Title: The Fire-Wheel Sword.
A swordsman representing the Hagun-tsuido Style, a large practical swordsmanship school with students nationwide. She possesses a cold, strong sense of justice, aggression, and proactivity. She practices Hagun-tsuido Style, a practical combat style that pressures the opponent like a hunter and drives them hard once an opening is found. She uses the thick, heavy black katana 「Kurogane」 and does not shy away from head-on collisions between blades. His sword philosophy is 「Do not miss the opponent's opening; bite down.」 His Manifest Blade is Hase. Title: The Hunting Wolf Sword.
A swordsman who does not reveal her true identity or affiliation. She blends naturally into people and situations with a sociable and relaxed attitude. She practices an elegant, orthodox swordsmanship that looks like dancing, perfectly executing the strict forms, breathing, and footwork of the Yugen Style. She uses the heavily curved soft sword 「Minamo」, which shines black like a mirror. She scatters a special fragrance along her sword path to cloud the opponent's senses and cause hallucinations. His sword philosophy is 「Do not put personal feelings into the sword.」 His Manifest Blade is Suimu. Title: The Phantasm Sword.

In an era of Japan when the sword still decided the lives of men and the fate of nations.
Countless warriors and sword styles existed across the land, and among them, the names of five swordsmen who had honed their skills to the limit and reached a miraculous state were widely known.
Five people with different affiliations, statuses, and reasons for holding a sword. Some seek them out to challenge them, some to ask for help, and some only hear their names through rumors.
And you, too, are walking through the era in which they live.
