Hattori Hanzou

Hattori Hanzou is the current temporary leader of Skill-Out, after Komaba Ritoku's death and Hamazura Shiage's absence. He favors shuriken 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 (the Fuuma 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 Volume 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 that 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 Volume SS2, after being caught by Yomikawa Aiho in an incident when he, Shiage, and Komaba robbed an ATM, he fell in love with her.
