Magic Stones

Magic Stones (魔宝石) are special gemstones with magical properties.

They are one of the two essential components of the Wizard Rings, the other component being the ring itself. Without a Magic Stone, the Wizard Rings would be as useless as any other ring. Wajima claims that the crafting on the rings depends on the resonance of the stones that he use, but he does not know what magic they are imbued with until they have been tested by Haruto.

When Shunpei looked at all the rings made by Mr. Wajima, he found one Magic Ring which was useless, which he suggested was a 'dud' ring. Soon after a White Garuda came and delivered a red magic stone which reacted with the ring. Wajima took the stone and used it to create the Flame Dragon Ring.

Agent Kizaki came to the possession of a green Magic Stone and had Wajima abducted so he could make him a Wizard Ring. After Haruto saved Naoki Katayama, Kizaki returned Wajima and gave him the Magic Stone as a gift,  which Wajima uses to create the Hurricane Dragon and Thunder Rings.

Later, Wiseman creates a blue Magic Stone. Unfortunately, because his sudden disappearance, Koyomi easily takes the stone with the help of the White Wizard's Black Cerberus. Like the green Stone from before, Wajima used this Magic Stone to create the Water Dragon and Blizzard Rings. However, Wiseman had actually allowed the White Wizard to find the newest Magic Stone.

When Haruto Co. seperate to find Kosuke, Koyomi came across by a bubble gum man. The man then toss the yellow Magic Stone to Koyomi, before he disappear.
