Sun Devil: Ambassador of Evil.A Dynasty warrior arrives on Earth, landing in a volcano named Mount Aso. The volcano erupts at his arrival, but the warlord uses black ice to calm it. At the same time, Ully, Mia, White Blaze and Ryo visit another volcano in an attempt to fix the Swords of Wildfire. The power of the volcano successfully repairs the swords and the group heads back home, but Ryo senses the nearby presence of the warrior, though he dismisses it. On the ride home, Ully encourages Mia to race White Blaze who seems to be back to normal after being restored by Black Blaze, the power of whom he now carries inside. At home, the Warriors see a news report about the eruption of Mount Aso and the ice that now covers it and decide to investigate. On the road, the warrior appears and Ryo engages in a battle with him, but proves to be no match for him. The warrior proves to be more than a match for all of the Warriors together and nearly kills Ryo before White Blaze knocks him away, knocking off his cloak. The warrior introduces himself as Sun Devil and explains that he was sent by his master to test their armors limits, but refuses to identify that master. Sun Devil splits into five copies which easily overpower the Warriors, but White Blaze attacks the one fighting Ryo and transforms into Black Blaze who has become a part of him ever since he saved White Blaze. At the insistence of the others, Ryo forms the Inferno Armor even though it will drain their power. Sun Devil explains he just wanted to see the power of the Inferno and freezes the Ronins in black ice, but Ryo breaks free and destroys Sun Devil with Rage of Inferno and the Soul Swords. A gateway to the Nether Realm appears and Sun Devil's master speaks to the Ronins through it, revealing himself to be the still-alive Talpa who is determined to have the Ronin armor return to him.
