As an assistant to Hakuryuu Taitei, who inherited the name of Ryuutei, this is the new form of Sekiryuu Gundam, who was given the Armor of Ryuo, a piece of Ryuukihou. It is said that the Armor of Ryuo allows the Sekiuu to see its surroundings as if it were looking down from the sky, and when it is worn by Sekiuu, its ability to pinpoint the enemy's position is greatly increased. This has become a great asset to Sekiuu, who also serves as a military strategist. In addition, the Fire Dragon Stone on his left shoulder has honed his fire magic skills. He travels to Aku with the Hakuryuu Taitei and rushes to save Rekkou from danger.
