As he grows stronger and deepens his bonds with fellow corps members, Tanjiro battles many demons alongside his comrades Zenitsu Agatsuma and Inosuke Hashibira.

They find themselves in the demons’ stronghold – the Infinity Castle, setting the stage for the final battle between the Demon Slayer Corps and the demons.
