You might love love, but do you love it enough to wear a giant "LOVE" on the helmet you wear into combat? Because that's what the trusted Uesugi commander, Naoe Kanetsugu, was famous for!
This is the "Ai" from the name 
of the god of war, Aizen Myouou!
Es el símbolo del dios de la batalla.
Esse é o "Ai" de "Aizen
Myouou", deus da guerra!
