Tanjiro punches Inosuke so hard he cracks his ribs, sending him sprawling. He tells him Zenitsu won't fight because they're both Demon Corps members and they're not supposed to draw their swords on each other. Inosuke takes that to mean it's alright if they fight bare-handed and proceeds to charge Tanjiro, which isn't what he meant. The two fight and when Inosuke doesn't stop, Tanjiro head-butts him, which makes Inosuke's boar mask fall off, revealing a very human, though beautiful and girly face. Inosuke collapses from a concussion, though Tanjiro is fine...
