Height: 175cm Weight: 56kg Birthday: June 26th Age: 27 Favorite Food: Soba Blood Type: AB Voice Actor: Akira Ishida A slender young man with handsome features, characterized by his long, straight black hair. He is the leader of the anti-government faction, the "Joi Faction." He is a childhood friend of Gintoki Sakata and Shinsuke Takasugi, having studied together under Shoyo Yoshida, and was their comrade-in-arms during the Joi War. He holds aliases such as the "Nobleman of Fury," the "Dawn of the Joi Patriots," and "Runaway Kotaro." Due to his surname and long hair, old friends like Gintoki, Takasugi, and Tatsuma Sakamoto call him by the nickname "Zura," to which he habitually retorts, "It's not Zura, it's Katsura!" Like Gintoki and Sakamoto, he often speaks his own mind indifferently regardless of whether he's actually listening to the other person, frequently getting on people's nerves. He speaks in a stiff, formal samurai-like tone and is often seen with his arms crossed. While he upholds a philosophy of simplicity and frugality, preferring plain meals like soba, he is paradoxically more interested in worldly affairs and material desires than others. For better or worse, he shows fewer changes in facial expression than other characters and rarely loses his composure visually. However, even if his expression remains calm, his actions can become extremely erratic. His sense of slang and behavior is outdated, using terms like "Baibee" or "Nyan-nyan," though on very rare occasions, he may use more casual phrasing like "-jan." He is prone to delusions. According to Gintoki, his type is "married women." However, he denies this, insisting he simply appreciates the "NTR" aesthetic.
