Demon Slayer Season 4 will Zenitsu and Inosuke get the center stage in the final battle

Demon Slayer Season 4 is under production and Ufotable recently announced its teaser visual. This has kept fans at bay, with many anime fans wondering whether Inosuke and Zenitsu would return to the Hashira Training Arc or not and if they would make their way to the Final Battle Arc. The Swordsmith Village Arc did not have Zenitsu and Inosuke but will we get to see them on center stage in the upcoming Infinity Castle Arc?

Demon Slayer Season 4: Zenitsu vs Kaigaku in the battle at the Infinity Castle

Demon Slayer Season 4 leads Zenitsu as a prepared swordsman into the Infinity Castle Arc. Zenitsu encounters Kaigaku, a senior of Zenitsu, at the Infinity Castle. They engage in a furious conversation and Kaigaku insults Jigoro, Zenitsu’s teacher. Their battle begins with Kaigaku using Thunder Breathing Fourth Form: Distant Thunder and attempts to kill Zenitsu, however, the latter easily slashes through this.

Kaigaku employs several breathing forms to attack Zenitsu, including the Thunder Breathing Third Form and Thunder Breathing Sixth Form.

Zenitsu starts falling, but at this moment he realizes and looks back at his relationship with Kaigaku. He jumps onto a wall and reflects at Kaigaku with his own breathing form- Thunder Breathing Seventh Form: Honoikazuchi no Kami and beheads Kaigaku.

The battle ends with Kaigaku cursing Zenitsu and Zenitsu being rescued by Yushiro. He gets into a dream where his master, Jigoro, tells him, “Zenitsu, you are my pride and joy.”

Doma reveals that he indeed killed Inosuke’s mother as he gets a look at Inosuke’s familiar facial features. Inosuke vows to put Doma through hell and thanks him instead.

The battle ensues but Doma soon tries to retreat and kill the rest of the Demon Slayers. But as he was about to leave the room, his hands are sliced off and he realized that he instead consumed a self-poisoned Shinobu. During the final strikes, Inosuke and Kanao together behead Doma as he is weakened by Shinobu’s poison.

They will fight alongside other demon slayers to keep Muzan at bay until dawn. They will assist Tanjiro and the other Hashiras in fending off Muzan’s attacks and their contribution will be greatly valued during the final battle.

Moreover, they will be highly accredited with bringing about crucial moments into the narrative and will take a central stage in defining the essence of the story.
