Hey there Noumii! (I hope you don't mind me calling you like that)

A Chi-You is vulnerable in the legs by crush type of damage. It can be from Bullets and even it's own Aragami Bullets too. There are quite a variety of BA's you can depend on that, mostly centered on Buster Blade and Boost Hammer, or the IE Chain Explosion for Long Blade primarily.

Unless you get a Short Sword with Crush type of damage (I believe RB has one such :V) You will have a very hard time to unbind the legs with Short Blades.

As for breaking the cape of a Vajra, that can't be done. If it were a Dyaus Pita, then it would be suspectible to Divine and Crush type of damage, but Vajra and the Prithvi Mata are practically immune to be damaged by their capes.

Hope this helped.
