Dranzer is Kai's Bit Beast.It's definatly one of the more powerful. Kai is very skilled at commending Dranzer and making it attack in way inumaginable. His Fire Arrow Attack is that the blade "jumps" in the air, then Dranzer comes out of it, fire comes aorund the blade, and it falls, right in the middle of the opponent's blade, usually destroying it. I'd say his most powerful attack is Flame Saber. Dranzer an arrow of fire and goes into the opponent's Bit Beast.

Dranzer's one of Kai's rare friend. He's loyal to him. He'll always be there for him. The bond they have together is undying, undestroyable.
