I love the design and I'm pretty sure it's Zack(the black haired co-second in command) instead of Peco(broken arm) who will use it. They both have around the same amount of speaking lines and he seems like the more competent of the two(That, and we have seen that he has the Walnut lockseed and I'm pretty sure he never lost it). This would also allow Kaito to have one of his team mates back him up as another armor rider while still keeping Peco as a morality pet. Besides, if Peco's arm is really broken I doubt he'll be able to use the belt.

*edit*

Forgot to add...guess this means Peco will finally have his nuts to go along with his banana ;P
