Shuren of the Flames (炎のシュレン Honō no Shuren)
Shuren is a member of the Nanto Goshasei and leader of the Crimson Army. He uses a unique martial art which manipulates phosphorous to engulf enemies with deadly flames.
After the death of Huey, his "brother star", Shuren mobilizes his Crimson Army against Ken-Oh's forces to take his revenge. Shuren preemptively ambushes Ken-Oh's army with flaming arrows as they enter a valley.
Afterwards, Shuren fights against two of Ken-Oh's most disciplined warriors before challenging their leader. Learning from Huey's mistake of fighting Raoh head-on, Shuren blinds Raoh with fire and manages to attack him from behind but Raoh reacts in time, crushing Shuren's fist and shattering his follow-up kick. In a last-ditch effort to stop Raoh reaching the Last Nanto General, Shuren performs a self-immolating attack. This proves futile against Raoh, who declares that Shuren's flames will never consume his ambition, and brutally snaps his neck.
