If it wasn’t already clear, it’s certainly obvious now that Inosuke Hashibira is the best player in Demon Slayer: Kimetsu no Yaiba, in the Entertainment District arc. This boar-headed demon slayer briefly brought the world together by making viewers around the world wince and tell them “this is disgusting”, as he manages to track down Tengen Uzui’s last missing woman. Inosuke has been at the top of his game for the second half of Season 2, succeeding where Tanjiro and Zenitsu failed and managing to turn viewers’ stomachs along the way.
It’s not like the internet has agreed on anything, but the consensus seems to be that Inosuke’s ability to disrupt every joint in his body is really, really disgusting. Following Tanjiro’s hypothesis that there must be tunnels between the houses through which the demon they are hunting moves, Inosuke demolishes the Ogimoto house until he finds a small hole in the ground. Unfortunately, it’s too small for the “Beast-Breathing” swordsman to fit through.
However, “Lord Inosuke,” as he is often referred to in Demon Slayer, was never one to let logic or physics get in his way. Realizing that only his head can fit in the hole, Inosuke decides to dislocate all the joints in his body, because of course he can. Turning his body into a soft noodle, Inosuke dives into the hole and sinks underground, giggling like a maniac. He ends the suffering of the public by putting his bones back in place after reaching a large cave. This is where Inosuke proves Tengen’s mission would never have succeeded without him.
At the start of the episode, Tengen is hunting in the city when something grabs his attention on the ground. With his ear glued to the ground, he can hear the sound of someone fighting below the surface. The story then jumps back in time to “a little earlier”, when Inosuke discovers the hole under the floor and locates Daki’s “food locker”, where he quickly frees Makio, Suma, and Zenitsu. The group begins to fight the Demon of the Kimono Belt which appears to be an extension of Daki’s will, and the sound of their fight catches Tengen’s attention from the surface.
Inosuke’s ability to dislocate his joints – which, again, is yuck – means he’s the only one who could have reached Daki’s food locker. Tengen probably wouldn’t have located the underground chamber on his own without the sounds made by Inosuke and the others to show him the way. If Inosuke had not found them, the women of Tengen, Zenitsu, and all of Daki’s other victims could have been lost forever.
It’s surprising that Inosuke had such a performance in the entertainment district, when he should be the least fit to operate undercover in a bustling city. Still, of the six people Tengen sent undercover, Inosuke is the only one whose cover was not immediately discovered. The first to meet Daki and learn that she can travel within Walls, Inosuke hunted demons while Tanjiro did his household chores without cheating on anyone and Zenitsu played the shamisen.
Inosuke had a series of great character moments in Demon Slayer’s “Entertainment District” arc. This tendency could make him the hero of this particular conflict, or it could be his last chance to shine before tragedy strikes. Now that Tengen’s women are safe, the group will likely converge on where Tanjiro fights Daki alone. With Inosuke on a good streak of success, he’ll be eager to join the fight. Upper-Six doesn’t appear to have revealed her true power yet, which could prove disastrous for anyone who could brazenly challenge her, as Inosuke is accustomed to doing.
