|Anime debut||Yu-Gi-Oh! VRAINS episode 1: "Link into the VRAINS"|
Like all Ignis, Flame is a small digital humanoid being. Like other Ignis, Flame has markings over his body, in shape of lines, circles, and "flaming shapes". Flame is a dark red in color, with bright red markings and glowing yellow eyes. In comparison to Ai's "pointed hat" shaped head, Flame's head resembles fire. During the prologue of the series, Flame's form is obscured in crimson energy.
Appropriately, Flame is described as hot-blooded by his voice actor, Taku Yashiro. Flame acts haughty and proud, but is more obsessed with facts and figures than he lets on and eager to show off.
As explained by himself, his name is a pun, written as "indomitable soul dream" in Japanese Kanji, which when read sounds like the English word "flame". Takeru complained that he heard that explanation 10,000 times, but Flame deadpanned that it was only 37 times.
Flame and the other Ignis were created by Dr. Kogami to be the saviors of humanity; Flame was created from Takeru Homura. Alongside his fellow Ignis, Flame evolved and they created the Cyberse and the Cyberse monsters. Their progress worried Dr. Kogami, who predicted the AI and humanity would become enemies. Despite this, Flame and the other Ignis continued developing the Cyberse; Flame's sector becoming a large, active volcano. In Ai's words, the Ignis would never try to harm humanity, and would rather live in their own world.
Varis launched an attack on the Cyberse with three of his "Cracking Dragons". Flame and the other Ignis were sealed off and could not retaliate, except for Ai. Varis and one "Cracking Dragon" chased Ai, who escaped and severed the connection to Cyberse's location. Flame and the others realized that Ai meant to hide their world, at the price of being unable to return. Just as Ai succeeded and gloated about it, the pursuing "Cracking Dragon" devoured him.
In LINK VRAINS, Flame and Soulburner observed Playmaker's Duel with a glowing Duelist; Soulburner noted that Flame's friend was with Playmaker. Flame asked him not to associate him with that airhead. When Haru sent two Duelists, Bit and Boot to deter Playmaker from pursuing him, Soulburner arrived to deal with them and allow Playmaker to continue pursuing Haru and Bohman. Flame revealed himself to Bit and Boot, and they observed that he was the FIRE Ignis and that they needed to capture him. Flame introduced himself, explaining the meaning of the kanji in his name, and Soulburner told him to knock if off because he'd told him a thousand times already. Flame retorted that it had only been 37 times. Soulburner challenged Bit and Boot simultaneously, and they merged into a single Avatar, BitBoot for their Speed Duel.
BitBoot demonstrated both Cyberse-Type monsters and the Link Spell Card "Judgment Arrows" as Bohman had, bringing out "D-Scale Battle Coela" and using it in combination with "D-Scale Torpedo" to move it around the field and inflict 1600 damage to Soulburner. Flame noted that they could only take the combo three more times before losing, and Soulburner reassured him that he could break it, Link Summoning his ace monster, "Salamangreat Heatleo", using its effect to shuffle "Judgment Arrows" into the Deck before attacking and destroying "Battle Coela". On their next turn, BitBoot used their Skill again, despite normally only being able to use it once since Bit had used it the last turn and now Boot was using it this turn, reactivating "Judgment Arrows" in a zone that "D-Scale Fullmetal Dunkle" pointed to. "Fullmetal Dunkle" was so large that it damaged the buildings around them, but Soulburner was able to save himself and "Heatleo" with "Energy of Fire", which restored his LP and prevented the destruction of "Heatleo". Flame warned Soulburner that he'd need to draw a agood card, and although he was pleased to draw "Monster Reincarnation" on his next turn, Soulburner's field was locked down by BitBoot's "D-Scale Chaff". Soulburner then used his own Skill, "Burning Draw", lowering his LP to 100 and drawing a card for every 1000 LP lost, drawing "Salamangreat Sanctuary", allowing him to Reincarnation Link Summon another "Heatleo" and once again shuffle "Judgment Arrows" into the Deck. BitBoot attempted to set up "Fullmetal Dunkle" to destroy "Heatleo" next turn, prompting Flame to cry that they were doomed. Soulburner replied that the match was already over, using the Reincarnated effect of "Heatleo" to lowering the ATK of "Fullmetal Dunkle" enough for "Heatleo" to defeat BitBoot. After they won, Flame claimed that he'd knew that they'd win, and Soulburner teased him for having given up hope earlier. Flame and Soulburner pursued Playmaker to the bottom of LINK VRAINS, where Haru and Bohman had escaped into the restricted area. As the area's defenses had been triggered, Soulburner suggested that they log out, and he told Playmaker his name and that they'd meet again before logging out with Flame.
This summary is currently incomplete.
After defeating The Gore, Soulburner and Flame met Playmaker and Ai again, and managed to enter the unknown world through its portal. Immediately after arriving, they were hit by strong winds, which forced Ai and Flame to protect them using Data Storms. At some point, the winds stopped, and they were able to reach a temple where they finally found the wind Ignis. After showing them the world he had build, the Ignis (who decided to call himself "Windy") explained how he did that in order to attract his fellow Ignis, and also to lure the responsible for destroying the Cyberse World. Despite not knowing who was the responsible, Flame pointed out they were after Bohman, who not only had stolen Jin's consciousness, but also had the card used to destroy the Cyberse World, and suggested he could've escaped to a world inside Windy's world. They then asked Windy to join them, which he promptly refused, as those statements had no evidence. However, Windy said he could weaken the winds near the area where Bohman supposedly escaped to, under the condition that Playmaker and Soulburner defeat the two invaders, Ghost Gal and an unknown partner.
Upon making contact with the girls, Blue Girl presented herself as actually being Blue Angel. Soulburner was happy to meet another savior of the old Link VRAINS, but Blue Girl stated they were actually seeking to retrieve the Ignis. While both Playmaker and Ghost Gal were willing to solve the situation without Dueling, Soulburner accepted Blue Girl's challenge. From the very beginning of the Duel, Blue Girl was planning ahead to counter Soulburner's strategies of swarming the field with "Salamangreat" monsters, and his Skill. Soulburner was pushed into a corner by all accumulated burn damage caused by "Trickstar Divaridis" and "Trickstar Lycoris", and even "Salamangreat Heatleo" was unable to destroy them due to Blue Girl using "Trickstar Calobane". Despite making no progress, Flame still assured they had an advantage, since Soulburner had Flame himself by his side. After nearly being defeated by Blue Girl's Fusion Monster, "Trickstar Band Sweet Guitar", Soulburner listened to Flame's advice and used his Skill, managing to draw "Fusion of Fire". By using it, he fused "Heatleo" and Blue Girl's "Divaridis" into "Salamangreat Violet Chimera". In the final attack, Blue Girl attempted to reduce the damage by using "Calobane" again, but this was predicted and countered by Soulburner, who used the effect of "Violet Chimera" to double its ATK, and drop her LP to 0 in a single attack. After the Duel, he approached the fallen Blue Girl to compliment her for becoming much stronger, before forcing her log out. Ghost Gal then returned, amazed by the Duel's outcome and aware she wouldn't be able to go any further without her partner. Flame then gave her a copy of Blue Girl's evacuation program, allowing Ghost Gal to log out safely.
