Warning: Spoilers ahead.
This is it! The very first episode of the second season of Demon Slayer: Kimetsu no Yaiba! After waiting years, we finally continue the story in anime format!
This is the beginning of the Entertainment District Arc, which sounds like a very fun setting to me. Giggles. We get an hour-long episode to kick it off.
The ep begins with the final fight and death of Rengoku-san. It’s a painful loss for Tanjiro, and it causes him to bawl. We finally see what happens right after. The Demon Slayer Corps medical team comes to pick up Tanjiro, Inosuke, and Zenitsu. Even Inosuke is bawling.
Then we see a creepy child. Surprise, it’s Muzan! He’s posing as the brilliant adopted child of a family. What is up with all these fake lives of Muzan? Weirdo.
Akaza reports to him in secret. Still no sign of a Blue Spider Lily flower that Muzan wants. He also reports that he killed a Hashira (Rengoku). But Muzan is far from impressed. Just by pointing at Akaza, he’s somehow able to wound the Upper Three’s entire body. Muzan is disappointed that Akaza didn’t kill the other Demon Slayers, and punishes him for it.
Muzan dismisses Akaza. And Akaza is filled with rage. He destroys Tanjiro’s sword and vows to kill Tanjiro next time they meet.
Meanwhile, Tanjiro follows Rengoku’s last request and visits Rengoku’s family home. He passes on Rengoku’s last words to Senjuro. But Rengoku’s father isn’t happy to see Tanjiro. He’s an angry belligerent drunk. And says something about Tanjiro being an inheritor of the Sun Breathing technique - that all other Breathing techniques mimic technique, which was the first one. Maybe it’s the Hinokami Kagura? Anyways, Rengoku’s dad insults his dead son. Tanjiro defends Rengoku and even gives the dad a head-butt!
Tanjiro wakes up. Senjuro gives him the notebook that Rengoku was talking about. But it’s all ripped to shreds. So he can’t learn any information from it. Rengoku’s dad tore it up.
As a parting gift, Senjuro gives Tanjiro the guard of Rengoku’s Nichirin sword. And later, Senjuro passes on the final words of Rengoku to his father. Which makes the old man cry.
Side bit - Haganezuka chases Tanjiro all night long for having lost his sword! Just a bit of fun.
Four months pass. Tanjiro, Inosuke, and Zenitsu recover in the Butterfly Mansion and train intensely.
One night, Tanjiro and Nezuko go on a mission to slay a demon. They do so. They come back and find Tengen Uzui, the Sound Hashira, “kidnapping” Aoi and Naho!
Kanao at first doesn’t intercede, not wanting to disobey a superior. But she finds the resolve and tries to stop Uzui. Tanjiro also tries to stop him, saying it’s wrong to treat these girls this way.
Tanjiro is backed up by Inosuke and Zenitsu. They volunteer to take the girls’ place. So Uzui drops Naho and Aoi. And off to the Red Light District they go!
