Inosuke has gotten stronger throughout the series, and that has led to several victories, none of which would have been possible without Tanjiro.

Inosuke stole the spotlight in the latest episode of Demon Slayer. When things were looking dire, he took control of the situation. With the help of Zenitsu and Tanjiro, he was able to close the distance on Daki and sever her head. Inosuke even quickly came up with a plan to make sure that she wasn't able to reattach her head while the others fought her brother.


It's hard to imagine that the same Inosuke who was introduced in Episode 11 would be able to trust his comrades enough to execute a plan that required teamwork. Out of every character in Demon Slayer, Inosuke has demonstrated the most development out of anyone. He has been transformed from the belligerent wild man he was before into a competent member of the Demon Slayer Corps. A lot of this change is because of Tanjiro.


Before Inosuke was a part of the iconic Demon Slayer trio with Tanjiro and Zenitsu, he was a loner whose personality naturally pushed people away. His only focus in life was to prove his strength by fighting powerful opponents. This mindset made it nearly impossible for him to make friends or even trust allies, and he constantly attacked those around him.

Inosuke joined the Demon Slayer Corps purely by accident. He met a Demon Slayer member by chance and beat him in a fight, then took his swords and decided to become a member. He wasn't motivated to join the Corps because he wanted to protect the innocent from demons or rid the world of evil. Instead, Inosuke joined because he learned that demons were powerful, and he wanted to prove that he was stronger.

Inosuke even showed that he was willing to attack humans in order to reach his goal. He fought both Zenitsu and Tanjiro when he sensed Nezuko's demonic presence in her box. During his debut, Inosuke showed that he was single-minded, arrogant and entirely focused on his own glory. However, spending time with Tanjiro slowly changed Inosuke for the better.
