Katuso as a 14 year old is tall, thin and muslcular.He has black hair and light-brown eyes.He usually wears casual clothes, but on battle, he changes to his Battle Suit.The Battle Suit is made up of a white kimono with a black cloth inside for the upper part. He also wears gloves specially desinged for fighting.For the legs, he wears black kimono leggings.On his feet, he wears specially desinged shoes.In his battle mode, he also has his two katanas seathed on both of his hips.

As a 30 years old man, he grows a lot more taller and his hair gets longer and wavy.His hair is tied in a long ponytail and has long bangs that frame the left side of his face. He wears a straw hat (called a sakkat) and a pink, flowered ladies kimono, which he drapes across his shoulders and over his white coat. Although his haori and obi sash are cheap, his pin-wheel hairpins are very expensive. He does not wear tabi with his sandals. He has thin facial hair around his mouth and on his cheeks.


At the age of 14, Katsuo was type of character that can make friends with everyone, and if not friendship, then at least respect.Katsuo can become angry when his friends or senseis are hurt or injured.He is also willing to sacrifice things important to him to save his friends from danger.

He is usually very serious in battles, and tries to finish off his opponents as fast as possible, the same as his former sensei, Sasagawa Kenshin.

Katsuo is also a quick learner, learning very fast every technique Kenshin showed him and a very talented fighter, being able to fight Richard after training with Kenshin for only 8 months.

At the age of 30, Katsuo's personality changes a lot.He becomes a laid back and flamboyant man, evident in his style of dress and general attitude, and he is rarely seen without a smile on his lips. In his off time, he can be seen drinking sake in bars and napping. He likes steamed buns that go with sake, but dislikes powdered green tea.He becomes a peace-loving man who will always try to talk his way out of a fight, though he doesn't wish to insult opponents by refusing to fight. The slightly eccentric Katsuo also seems to like making an impression on opponents. He also dislikes taking the life of innocent people.

Despite being one of the strongest swordsman in the world, Katsuo retains a level of humbleness and isn't overly arrogant about his strength, although when fighting Kyo, he does comment on how the fight "wouldn't be too easy" even after finding out that Kyo has trained with Kenshin.

Abilities and Powers


Katsuo is a very good swordsman.At first he was seen fighting with a wooden katana,but Kenshin gave him a real sword,then the 2 swords of Sadao.

  • 2 Sakamaku Ame 逆巻く雨 (Rolling Rain) - Defensive. Katsuo lifts waves of water around him, and then ducks, putting his swords protectively in front.
  • 3 Yarazu no Ame 遣らずの雨 (Last Minute Rain) - Offensive. Katsuo drops the katana, kicking it with his foot, to send it flying in a stab.
  • 4 Gofuu Juuu 五風十雨 (May Wind, October Rain) - Defensive. Katsuo synchronizes with his opponent's breathing to evade attacks.
  • 5 Samidare 五月雨 (Early Summer Rain) - Offensive. Katsuo slashes at their opponent, but instead of attacking, pulls out a feint. The user drops the swords and catches them with the other hand(drops the sword in his right hand, catches it with his left hand)then quickly slashes the off guard opponent.

  • 12 Sadachi: Kirisame (Brazen Left Blade: Drizzle)- Offensive. Katsuo uses the left sword to attack with multiple compressed airwaves which can cut the enemy into pieces and "Sniff" out an enemy, making this perfect against illusionists.

The main problem of Katsuo in a battle is his endurance.This thing is probably the only one that really makes him different from Kenshin.

When Katsuo takes damage early in the battle, he usually losses, however when he is 30 years old things seemed to have changed since he took a lot of damage and was still able to fight at full power.


Since he is a swordsman, Katsuo uses swords when he is fighting.

Katsuo was first fighting with a wooden katana, then with a normal katana and now he is fighting with the 2 swords of Sadao, Jirou and Kojirou.
