An extra fanservice episode and hopefully some extra focus on Toa? Well, keep dreaming. Dragonaut - The Resonance Special is probably one of the worthless special episode ever.
The plot is non-existant, it starts off with some random scenes. The opening song appeared like 8 minutes after the start and after that it moves to another random plot. The art, sound and characters pretty remained the same, nothing too good. Overall it's horrible, it's the worst thing you can get, no plot and no fanservice.
