活撃/刀剣乱舞

In 1863, with Japan split between pro- and anti-shogunate forces, a Retrograde Army is sent back from the future to rewrite history. To stop it, a master called the Saniwa gives human form to legendary swords as Touken Danshi, sword warriors. Izuminokami Kanesada, hot-headed and skilled, and the calm Horikawa Kunihiro, both once carried by Hijikata Toshizou, arrive in the bakumatsu-era streets alongside Mutsunokami Yoshiyuki and others to guard the timeline against the invaders.
