Ichiro is stained with special indelible ink, which is a marker for SHADOW's deadly Bloodlust swords. Big Shadow equips his new Roninbots with the killer katana to hunt down and destroy 01. Mari goes on a search for a flower than can dissolve the ink, and comes across Waruda. Unable to articulate his feelings for Bijinda, while being hunted by the Roninbots, Waruda challenges 01 to a final duel.
