Shichika spends twenty years isolated, then travels twelve episodes collecting swords he'll never use while falling in love with a woman who's using him. Each sword-bearer forces the show to stop and ask what purpose even means. By the end, that repetition isn't a flaw, it's the point. Togame's laugh is the only thing that ever mattered, and the show understands this before you do.
Shichika has spent two decades isolated on a quiet island with his sister Nanami, practicing Kyotouryuu, an unusual martial art in which his own body serves as the blade. His life changes the moment Togame, an ambitious strategist for the shogunate, arrives with a proposal: join her on a dangerous journey to hunt down twelve legendary swords forged by the master smith Shikizaki Kiki. The catch is that each blade is guarded by a skilled warrior who won't part with it willingly, and other power-hungry rivals want to stop Togame's mission. Shichika agrees, drawn more by Togame herself than by politics, and the two must become a strong team to survive the road ahead. Set in an Edo-era Japan full of competing sword styles, the series mixes action, adventure and romance.
