The buckle is indeed interesting, but I do wish the form & the power-upping it grants were better. All the form becomes is: (the under armor throughout the whole body is Ninja up & below) the upper armor of Command Twin but all painted black, a regular plain black cape, and is given just a plain katana for a weapon
That's intentional as with all the buckles that have electronics in it. X Geats and Geats 9 also function without the need of having the Desire Driver on as it functions using a small little button that activates all the sounds programmed into the buckle.
Honestly Bujin Sword's form isn't really that impressive since a majority of the form-armor appearance is just a black-repainted Command Twin form of the upper armor, a black cape, and is just granted a regular katana for its form weapon
I feel like bandai is trying to copy hasbro release style, which isn't working even for it, with how the release schedules has been divided between normal, special and premium releases regardless of the items
Once I replace the batteries in my desire driver, I will have to remember that “holding down the release button while inserting the raise buckles” trick.
