Chapter 31: Leting Someone Else Go First

The chapter begins with Inosuke attempting to get Tanjiro's attention by trying to throw one of the demon slayers up into the tree. However, the Mother Spider catches onto their plan and quickly kills the demon slayers shes controlling as puppets. Inosuke calls out in frustration after realizing that they're all dead and notices Tanjiro hunched over besides one of the bodies, he senses a dark aura being emitted from him and immediately agrees when Tanjiro says they need to go.

Tanjiro and Inosuke encounter the "doll"

They travel quickly through the forest and approach the strong odor of a demon, however they begin to panic as they realize that its a headless body being used as a puppet. Tanjiro attempts to formulate a plan to take down the puppet, however Inosuke charges forward and engages with the being. To his disadvantage, Inosuke sustains multiple slashes and unknowingly gets entangled by a spider's thread, he panics as the headless puppet prepares to pierce through him.

At that moment, Tanjiro quickly comes to Inosuke's defense and deflects the puppet's attacks, he manages to push back the puppet and yells to Inosuke that they need to fight together in order to defeat it. In an angered protest, Inosuke calls him out saying "I won't let you embarrass me anymore!"

The puppet charges forward to attack, however the boys prepare their counterattack together, Tanjiro bends over to evade the attack and tells Inosuke to go over his back. He successfully slices both of the daggers from the puppet and leaps into the air off of Tanjiro's box, meanwhile Tanjiro uses the Water Breathing: Third Form - Flowing Dance to demobilize the puppet by slashing its legs. As Inosuke descends from above, his jealousy at Tanjiro's skills and abilities builds up and he powerfully delivers the final blow to defeat the puppet demon.

Tanjiro is amazed by Inosuke's final cut but becomes stunned when Inosuke suddenly charges at him. Inosuke exclaims that "I can do anything you can do dummy!" and furiously throws him up into the air.

Nearby in the forest, the Mother Spider Demon sits defeated on her rock after her strongest doll was defeated. She upsettingly blames Rui for her defeat since he had threatened her to do well.

As Tanjiro spots her from above and prepares to attack, the Mother Spider Demon panics when trying to formulate a plan however she comes to realize that she will find freedom and peace in death. She holds out her arms and accepts her fate. Tanjiro notices the change in her demeanor and switches from using the Water Breathing: First Form - Water Surface Slash to Water Breathing: Fifth Form - Blessed Rain After the Drought.

Chapter 30 :- Puppet Dolls

As the trio of boys continue to fight the possessed demon slayers, Murata advises the other two chase down the demon while he handled the swordsmen. In response, Tanjiro thanks Murata quickly drags a protesting Inosuke deeper into the forest with him.

Tanjiro and Inosuke discover the female swordsman

Inosuke and Tanjiro sprint through the forest, en route to the demon, when they stumble across a crying female corps member. She pleads with them to stay away and bring a stronger swordsman to help, warning that demon will control her to kill the remaining swordsmen.

Elsewhere in the forest, a female demon is seen giggling on a rock with excitement, as the boys come closer and closer to her stronger puppets. The mysterious boy from the previous chapter—whose name is revealed to be Rui— stealthily appears behind a tree and calls out to the demon calling her "Mother". She flinches upon seeing him and breaks out into a sweat, Rui asks her if she is capable of winning and threatens that if she doesn't do so in a timely matter, then he will tattle to his "Father".

Rui threatens the Mother Spider Demon

Mother becomes frantic and assures Rui that she is capable of the assignment and protecting him, saying that "Father" does not need to get involved. Rui backs away into the forest while ominously telling her to hurry up.

With a newfound sense of urgency, the Mother demon begins to operate the corps members with more violent jerks. The female swordsman begins to quickly lunge and slash at the boys while her bones twist and crack in unnatural ways. Tanjiro dodges her attacks and sees two other corps members pleading to be killed and put out of their misery due to the pain.

Tanjiro successfully tangles Ozaki in the tree

Without hesitation, Inosuke agrees and tries to attack them but is told to wait by Tanjiro. He begins to ponder on how to immobilize them without hurting them anymore then they already are. Tanjiro runs in the opposite direction as the female swordsman gives chase, he sprints then turns back quickly to grab and throw her into the air. The girl gets caught on a branch and remains tangled within the canopy of the tree.

Inosuke stays standing in disbelief and eagerly follows Tanjiro's lead, he grabs a nearby corps member and successfully throws him into the tree where he stays tangled. He turns to face Tanjiro and tries to mock him by saying that is capable of doing anything that Tanjiro can do. In a comical response, Tanjiro apologizes to Inosuke for not watching what he was doing which angers him.

The chapter ends with the Mother demon twitching in anger as she is forced to bring out "that doll", alluding to something more powerful.
