Personality[edit | edit source]
He was a believer that females are naturally weaker than their male counterparts and are therefore unsuitable to be warriors. Koushirou deeply appreciate talent as shown when he noted that as long as Zoro valued his swordsmanship he did not care if he had became a pirate. However, he was rather dismayed that the students of his dojo hoped to become great pirates like Zoro and started practicing Santoryu to better emulate him.
Although he is always seen smiling, he gives the impression of being a mostly emotionless person. Koushirou's reaction to his daughter's death was just a comment that "humans are fragile" when telling Zoro that she died, though it is possible that he was masking his pain.
Abilities and Powers[edit | edit source]
He is skilled enough with a sword that he can teach others to use it. Having learnt from his father a samurai, Koushirou has knowledge of swordsmanship techniques known only in Wano which he would pass on to Zoro.
History[edit | edit source]
Past[edit | edit source]
One day, a young Zoro came to his dojo for a challenge. Koushirou pitted Zoro against his daughter Kuina and stated that if Zoro loses, he would become a student of the dojo. Zoro accepted the challenge and lost and became Koushirou's student as agreed.
One night, Koushirou discussed about Zoro's progress with a fellow teacher and was confident that Zoro would one day surpass Kuina. Kuina, having overheard this conversation, became outraged saying that she would be the world's greatest swordsman. Koushirou stated that as a woman, Kuina cannot be the world's greatest swordsman, causing her to be distraught.

Anime and Manga Differences[edit | edit source]
At the end of the anime's flashback of Zoro's past, Koushirou was shown with bits of gray hair when Zoro left Shimotsuki Village. Yet, his hair was fully black when Zoro received his second bounty. This is most likely due to him not yet having been seen outside of Zoro's flashback in the manga at the time.
In the manga, his actions are limited to Zoro's flashback while in the anime his role is expanded. Kuina's increased fighting potential is noted by him because of her rivalry with Zoro, while in the manga he makes no statement. His traditional values are also touched upon as he contemplated making Zoro his heir rather than his own daughter Kuina simply because of her gender.
