I mean, when Tanjiro did the sunbreathing at the end, it looked like he was literally awakening super saiyan-powers. I'm glad they didn't go the full length there :/

Hopefully the series goes back to more reasonable story-telling. I mean, there really were plenty of good, exciting options to get the heroes out of the situation at the end of last episode. Other hashira appearing. Nezuko awakening again. The 3 wives actually doing something. Some new character appearing. Muzan appearing and for some reason stopping the fight. My favorite: the brother demon realizing how similar Tanjiro and Nezuko are to him and his sister and killing himself with some "this brother and sister have a better chance to overcome this than us. Good bye ..."-thinking. Heck, another chilling conclusion would have been if, GASP, some of the heroes actually died. Because, you know, it's that dangerous of a battle.Innosuke and Zenitsu dying here would have made some real impact and it's not like they've proven to be some essential necessity for the plot.

And so on. Go crazy with fanfic. Most alternatives would have been better than this. It's the antithesis to HXH's Gon vs Pitou-fight. Or any HXH-fight really. When you put the heroes in a situation that's just too hopeless to be won by them, you have two options as an author: 1) write a conclusion about how they're saved by someone else or 2) bullshit themselves out of it by sheer power, wherever that power is supposed to come from. Obviously, the former is the better, more satisfying option. And even if you choose 2), then there should be lasting consequences, but that's not gonna be the case here, I bet.

Honestly, it annoys me extra much, because of how great the fight and death of Rengoku was. Great fight, exciting power struggle, tragic but reasonable conclusion. The outcome felt satisfying, because it was what was possible at that point in the story. Today's episode of KnY rather reminds me of One Piece and Water 7 where they met and fought CP9, and out of nowhere Ruffy had this Gear 2nd-technique that was never mentioned before nor any training arc was shown. Bullshit like that never feels satisfying.
