The year is 1863, Japan is split between the pro-shogunate and anti-shogunate factions. In this chaotic time, the era of the swords is coming to a close.

Horikawa Kunihiro has manifested as a Sword Warrior and is joined by Izuminokami Kanesada, a warrior who served under the same master as him. With a single goal in mind, the two rush through the mountains...

Sword Warriors are “Tsukumogami”, spirits and willpower that reside within a sword. These spirits are awakened by Saniwa to protect the world from the “Time Retrograde Army,” who were sent by historical revisionists from the future to alter history.

Along their journey, the two Sword Warriors encounter Mutsunokami Yoshiyuki, Yagen Toushirou, Tonbokiri, and Tsurumaru Kuninaga. They band together and devote themselves to confronting and defeating the Time Retrograde Army.

The fate of history lies in these hero’s hands. What destinies await the blades is yet to be uncovered...
