GuldStorm (ガルドストーム Garudosutōmu?, 35, 39, 40, 43-44, 48): A red and black Fenghuang monster with a tribal personality (including the turkey-feathered headdress) that wields a tomahawk weapon. Destroyed by Tiger's Crystal Break. Another one appeared in episode 39 where it was used by Kanzaki to save Yui from Psycorogue, before used to target Kagawa's family to blackmail him into giving up the Alternate Vent. But the monster was quickly driven away by Dragredder. From the end of episode 43 to the beginning of episode 44, a GuldStorm was among the monsters that helped protect Yui. In episode 48, Kanzaki had it prevent Yui's suicide and take her where she would not interfere with the Rider Wars.
