Traveling to modern Japan in 1860 AD, it was the end of the Edo Shogunate era, that is, the end of the Shogunate era. Overseas powers who completed the Industrial Revolution opened the door of Japan with steam warships, bringing turmoil and chaos to the country. Opportunity. Life by the sword, death by the sword, desperately defending the old era of samurai warriors; clamoring to fight against barbarians and founding the country, and vowing to establish a new era of reformers; beheading countless people in the name of Tianzhu, chilling people beheaded We...all of them are holding their swords high for the justice they insist on. In this turbulent era, Tachibana Qingdeng, who has become an ordinary policeman in Edo (today's Tokyo), has a copying talent system. People who have fought against each other can copy a talent from each other no matter they win or lose.
