The Demon Imperial Sword Zanvat Sword (魔皇剣ザンバットソード Maōken Zanbatto Sōdo) was a sword of great power crafted and used by the previous King until he tossed the weapon into Castle Doran's wall. By 2008, after sensing the power of Wataru as he evokes Kiva's Flight Style, the sword forced itself out of Castle Doran's walls. It then resisted being pulled by others until Wataru pulled it out by seeking more power.
