What is Aimachi?
Japanese guard who feels the need to make every other guard feel stupid and inferior with their awesome spinning skills. Not only do they spin normal guard equiment, but they also spin batons amazingly. They are known for their famous "double turn around" toss. Basically, these people are freaking amazing.
Did you see that chick toss her rifle and spin around three times then catch it while another girl threw a sabre over her head and then landed in the splits??? Yea, those girls are in Aimachi.
