You can basically cripple an army’s lines by striking them at a side-angle. This is the principal behind Rinko’s Rindo, his armies pushing the enemy formations outward, Moubu’sEchelon at Coalition, his army struck at a diagonal angle which crippled Kanki’s lines, and Riboku’s Houmei’s Ryudou, which forces charging armies to get caught up in the current and slowly die off.
So, I think this formation will literally spin like a propeller to act as a mixture of the Ryudou as well as Makou’s wave attack at Shukai. And if Kanki can move this spinning propeller forward at Riboku’s HQ, reserving his strong attackers like Zenou and the Shuma for the moment where Riboku’s head is within reach, I could see a formation like this devastating everything in its path lol, though of course a huge number of Kanki’s men would die in the process. This formation would almost be a suicide charge for the Kanki army. Man, the battle of Gian has been pure carnage thus far lol.
