Hattori Hanzou

Currently temporary leader of Skill Out, after Komaba's death and Hamazura's absence. Favors shurikens for combat, since he prefers to end fighting in the first blow. According to Kuruwa, a kunoichi who is familiar with Hanzou, he is a descendant of a ninja family (Fuma clan, though translations differ on the exact clan), who supposedly left when offered the place of becoming the head of the family and strike back at the Koga ninjas. His views on ninjas is that they should just hide in the flow of history, not be out in the open like Kuruwa suggests. In SS2 Hanzou is shown to be a very capable fighter and a good planner, even having knowledge of cases such as the 'gemstones'.

After Shiage defeated Mugino he offered the leadership of Skill Out back to Shiage, saying after that feat no one would question his leadership. Shiage declined, as he was worried about Rikou and told Hanzou to hold on the leadership for a bit longer.

Also in SS2, after being caught by Yomikawa Aiho in an incident when he, Shiage and Komaba robbed a ATM machine, he fell in love with her.
