Wizardragon

The WizarDragon (ウィザードラゴン) is the form of Haruto's inner Phantom Dragon (ドラゴン, Doragon) after he managed to hold on when he was in deep despair and push it back inside. Haruto usually keeps this Phantom inside him, which allows him the ability to perform magic. But when inside someone's Underworld, or when fighting particularly powerful Phantoms, Haruto summons his Phantom to aid him in battle with the Dragorise Wizard Ring.

Because of the Dragon's nature as a Phantom, and tendency to attack him, Haruto must attach the Machine Winger onto it in order to tame it. If this is not done, the WizarDragon will rampage, causing more harm than good. If released in an Underworld and not tamed quickly, the WizarDragon could quickly create a new Phantom, shown when the Dragon's attacks were just as effective at causing damage in Rinko's Underworld as her inner Phantom, Jabberwock, was.

But when the taming is successful, it results in a formation called Winger WizarDragon (ウィンガーウィザードラゴン). This version is not only loyal to Haruto, but has more powerful wings, and thus a faster flight speed.
