Still waiting for a chance when Oner and Reno can use their Drive Form (the only time when they used it is when fighting Mika, but they didn't even get to fight in it)

Thinking when the boss of this world shows up or if we have to fight the six senses here is when Oner/Reno will whip out those big guns. It should come as a surprise to the others since they haven't seen that form yet (well Belle has, but I think she wasn't fully conscious when she saw it)
