The full-series rebroadcast of Demon Slayer: Kimetsu no Yaiba reached Episode 16, “Someone’s Dream”, on July 26, 2026. Fans online called it one of the most memorable installments of the Natagumo Mountain arc, praising it as “an episode that hits just as hard no matter how many times you watch it.”

About the Series

Based on the manga by Koyoharu Gotouge, Demon Slayer follows Tanjiro Kamado, a boy whose family is slaughtered by demons. He joins the Demon Slayer Corps in hopes of turning his demonized sister Nezuko back into a human. The manga’s 23-volume Jump Comics run has surpassed 220 million copies in circulation worldwide. The anime, produced by ufotable, launched in April 2019 and has since expanded through multiple seasons. The theatrical trilogy Demon Slayer: Infinity Castle is now underway, with its first chapter opening in Japanese cinemas on July 18, 2025.

Murata Steps Up

The episode opens with Inosuke using his spatial awareness to locate the demon controlling fellow Corps members. When the group can’t advance, Murata — who made his debut in the previous episode — volunteers to hold the line, telling Tanjiro and Inosuke to go on ahead. Fans responded warmly: “Murata is so cool!” and “He’s such a good senior.”

Moving on, the pair encounter a female Corps member being puppeteered by the Mother Spider Demon, who tearfully begs them to bring someone of higher rank before she kills everyone around her.

The Spider Family’s Power Dynamic

Meanwhile, Rui pressures the Mother Spider Demon, complaining that she’s taking too long and threatening to tell their “father.” Terrified of the consequences, she pours more power into her controlling threads. Viewers sympathized: “The power dynamic in this family is disturbing” and “Rui is honestly the scariest demon in the whole series for me.”

Too Heavy for a Sunday Morning

The puppeteered Corps members move at unnatural speeds, their bones snapping under the strain. Some beg Tanjiro to kill them outright. Fans noted: “Watching them ask to be put out of their misery is genuinely painful” and “This is way too intense for a Sunday morning anime.”

Tanjiro devises a solution — he grabs the female member and hurls her into a tree, tangling her in the branches to stop her movement. Inosuke immediately copies the move and shouts, “Anything you can do, I can do too!” But Tanjiro admits he wasn’t watching when Inosuke did it, sending Inosuke into a fury. Fans loved the exchange: “Their dialogue is literally a comedy sketch” and “Inosuke just wanted Tanjiro to see him — like a kid going ‘Mom, watch me!'”

Fighting Together

The Mother Spider Demon sends out a new puppet — a massive body with no head, eliminating the obvious weak point. Inosuke charges in and gets caught in spider silk; Tanjiro rescues him and proposes, “Let’s fight together! Let’s think together!” Inosuke, though furious, begins to realize that Tanjiro reads the entire flow of battle rather than just charging forward.

The two coordinate: Inosuke uses Tanjiro as a springboard while Tanjiro’s Water Breathing technique creates an opening, and together they bring the headless puppet down. Fans cheered: “Their teamwork is incredible” and “Inosuke is actually learning!”

Fifth Form: Blessed Rain After the Drought

With her strongest puppet defeated, the Mother Spider Demon despairs. She looks up to see Tanjiro — launched skyward by Inosuke — drawing his blade for Water Breathing, First Form. But as Tanjiro reads her expression — the look of someone welcoming death as relief — he changes course at the last moment.

He switches to Fifth Form: Blessed Rain After the Drought (干天の慈雨). The blade falls gently. The Mother Spider Demon feels no pain, no suffering — only warmth, as if soft rain were washing over her.

Fans were deeply moved: “Tanjiro’s compassion cuts right through you,” “I was stunned the first time I saw that there was a merciful form like this,” and “He just lost so many comrades and he still showed her mercy.”

Before fading away, the Mother Spider Demon gazes into Tanjiro’s eyes and recalls a distant memory of someone once looking at her with kindness. She whispers her final words: “There’s a member of the Twelve Kizuki here. Be careful…” Fans noted: “The only reason Tanjiro got that crucial intel was because he chose to show her mercy — that was an incredible play.”

Voice Actress Comment: Ami Koshimizu as the Mother Spider Demon

Each week, the official Demon Slayer account shares a cast comment tied to the rebroadcast episode. For Episode 16, Ami Koshimizu — known for roles including Holo in Spice and Wolf, Ryuko in Kill la Kill, and Mizuki in Lycoris Recoil — shared her thoughts on playing the Mother Spider Demon:

“I’m so happy that the rebroadcast is giving everyone a chance to revisit these early episodes. Even though she was an enemy, I performed the Mother Spider Demon with the feeling that she was finally being given release and salvation at the end. Thank you for the rescue!”

Fans echoed the sentiment online: “Her final scene gets me every single time,” “Ami Koshimizu did incredible work here,” and “Her clear, beautiful voice made that ending so moving.”

Next Episode: Inosuke Finally Learns Tanjiro’s Name?!

The preview for Episode 17 teases that Inosuke may finally get Tanjiro’s name right — no more “Kamaboko Gonpachiro.” Fans are also buzzing that the next episode is “Zenitsu’s episode” and that it’s “the episode that got me hooked on Demon Slayer in the first place.”

The full-series rebroadcast began on April 5, 2025 — just one day before the seventh anniversary of the anime’s original premiere on April 6, 2019.
