Our school has minor arts. One is Pakua. What is another one?

The correct choice is Iaido, which is another martial art that focuses on the mastery of drawing and cutting with a katana. It emphasizes precision, control, and technique, making it complementary to practices like Pakua, which is also known for its philosophical and breathing exercises within martial arts.

While the other martial arts listed are valid and respected in their own right, they differ significantly from the context of Pakua. Aikido focuses on joint locks and throws and is based on harmony and the redirecting of an opponent's energy. Capoeira combines martial arts with dance and acrobatics, creating a unique cultural expression. Judo, on the other hand, is primarily centered around throwing techniques and grappling. Each of these has distinct principles and practices that do not align as closely with the characteristics of Pakua as Iaido does.
