Since Inosuke grew up in the mountains with only animals for company, he didn’t have the opportunity to learn established fighting techniques like Tanjiro’s water breathing or Zenitsu’s thunder breathing. Instead, he developed his own style called beast breathing, which takes advantage of his acute sense of touch to detect threats lurking in the shadows and unleash devastating blows upon them. The most impressive ability we’ve seen so far is his “spacial awareness” that he used to locate the Spider Mother demon in a dark forest crawling with other dangerous creatures.

Inosuke’s obstinate attitude can be either a good or bad thing, depending on the situation. He powers through the Final Selection exam by slaying demons in his own style instead of following normal procedure, but he also refuses to listen to Tanjiro and Zenitsu when they try to explain that Nezuko isn’t dangerous and shouldn’t be attacked. Luckily, he mellows out a bit over time, especially once Tanjiro earns his respect after the spider demon arc.

In distinct contrast to his muscular body, Inosuke’s face is fair-featured and even a little bit girly. He normally covers up his long lashes and luscious hair with his boar mask, but once Tanjiro sees his real face, he can’t help but admit that Inosuke is attractive. We wish we got to see unmasked Inosuke more often!

For all of his irreverent posturing, Inosuke still enjoys the simple pleasures of life, as well as being praised by people he begrudgingly respects. When something particularly good happens to him, like learning what tempura is or being thanked by Tanjiro, he sighs with contentment and little white puffballs float around his head. The fact that his mask is always on for these moments makes them even funnier!

Taisho-era Japan was a time of transition between traditional Japanese life and the encroachment of modern technology, so even small-town folks like Tanjiro are taken aback by electric lights and western clothing. But Inosuke has been isolated in the mountains for pretty much his entire life, so he’s on a completely different level of obliviousness. In the last episode of the first season, he tries to challenge a train to a battle (thinking that it’s an evil spirit haunting the land). Tanjiro calms him down by saying that it might be the guardian spirit of the town instead, to which Zenitsu sighs and calls them both country bumpkins.
