Daisuke Jigen

次元大介,

Lupin's marksman. He can perform a 0.3-second quick-draw and shoots with amazing accuracy. He prefers to conceal his eyes using his hat, as it gives him a more enigmatic appearance. His hat is also an important element to his dead shot accuracy because he uses it for aiming and target acquisition. He is also proficient in the use of many different firearms, such as machine guns, sniper rifles, and even a PTRS anti-tank rifle.
