PersonalityEdit

He was a believer that females are naturally weaker than their male counterparts and are therefore unsuitable to be warriors.[5] Koushirou seems to 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.[6] 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.[7]

Abilities and PowersEdit

He is skilled enough with a sword that he can teach others to use it.[4] His skill in swordsmanship is so great he has knowledge of techniques known only in Wano[8] he would pass on to Zoro.[9]

HistoryEdit

PastEdit

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.[5]

At least once, Isshin Dojo helped the Revolutionaries by providing them food and supplies. A man with a large face (probably Emporio Ivankov) was seen and Dragon said that the army received food from the dojo.[10]

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.[5]

On the day after Zoro and Kuina made their vow, Kuina had fallen down the stairs and died. On Zoro's request, Koushirou handed him the family's Meito Wado Ichimonji.[7]

Several years later, Zoro left the village to become the world's best swordsman.[5]

Water 7 SagaEdit

Post-Enies Lobby ArcEdit

After the Enies Lobby incident, Koushirou was seen again in his dojo when his students were asking him about Zoro. He wished Zoro to go on ahead and fulfill his dream. Koushirou also stated that as long as Zoro treasures his sword, it will not matter what person he becomes.[6]

From the Decks of the WorldEdit

After the news of the Straw Hat Pirates spread across the world, Koushirou was seen next to Kuina's grave.[11]

From the Decks of the World: The 500,000,000 Man ArcEdit

After the Straw Hats' victory at Dressrosa, Koushirou was dismayed that his young students began to imitate Zoro by practicing Santoryu and taping their left eyes shut.[12]

Anime and Manga DifferencesEdit

Koshiro Graying Hair

At the end of the anime's flashback of Zoro's past, Koushirou was shown with bits of gray hair when Zoro left the village.[5] 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.[6]

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.[5]
