In a Sengoku Japan reimagined with magic and mechs, Yasuke has set aside his sword to live quietly after years of violence, until the village sheltering him becomes a battleground for blood-hungry warlords. To protect Saki, a girl with a mysterious power that dark forces want for themselves, he takes up his blade again, drawing on the reputation he earned serving the daimyo Oda Nobunaga. This manga adapts the Netflix anime series of the same name.
