He practices Ninjutsu, which consists of weapons such as throwing stars, swordsmanship, small daggers, and a small knowledge of explosives. He also knows archery and is great at concealing himself. He will try to wear you down slowly through out a fight.
He doesn't talk much, and is very patient. He will hide all day in a tree just to wait until a target gets in just the right position.
He has a sword and sheath at his hip, a bow slung over his back, 10 poisoned arrows, 15 throwing stars in a pouch at his hip, a small dagger, and one crude explosive with a long fuse.
Sutesaru isn't well known, and he likes it that way. He wants his opponents to underestimate him and will sometimes downplay his own skills early in a fight as a way to make his opponent relax.
