assembled the strongest swordsman group.

In the midst of the turbulent late Edo period, known as the Bakumatsu era, foreign powers with advanced steam warships arrived in Japan, bringing about a time of great upheaval and opportunity. Amidst this chaos, a multitude of factions emerged, each with their own vision for the future: the pro-shogunate samurai fighting to preserve the old era, the Meiji Restorationists seeking to expel foreign influence and establish a new era, and ruthless killers who slaughtered countless people in the name of "Heaven's Punishment." Amidst this backdrop, Tachibana Aoto finds himself transmigrated into the body of an ordinary policeman in Edo (present-day Tokyo). Possessing a unique "talent copying system," Aoto can absorb the abilities of anyone he competes against, whether through victory or defeat. This uncanny power allows him to hone his skills and become the strongest swordsman of his time, as he navigates the treacherous landscape of 19th century Japan.
