I Fuse with a Little Golden Man and Join the Goddess Chat Group

Everything else is tolerable, but the protagonist is like a bootlicker. Anyone who asks for help, he's there like a lamb, offering no reward whatsoever. In Demon Slayer, at least he recruited the Butterfly Sisters. In One Piece, several female characters didn't contribute anything, even their travel expenses were covered by the protagonist, and they were each given a Devil Fruit at the end.

The writing is pure garbage; two-thirds of the plot consists of chatting. They're using the fully-formed power of the Little Golden Man to cultivate immortality. It's over 50 chapters and they're still chatting—it's incredibly padded.

The protagonist is a complete idiot who talks big but lacks any semblance of a powerful figure; instead, he's a goofy and stupid clown. He thinks he's showing off, but it only makes the reader increasingly cringe. He has absolutely no class whatsoever; he's more like a clown with invincible power who hesitates to reveal it.

It's genuinely boring. No pretentiousness whatsoever; it's just a bunch of losers who've gained power. What's the difference between inheriting Tartarus's power and some random character who destroys cities and nations? Tartarus is playing house in Demon Slayer, and writing chat scripts with Demon Slayer every day doesn't make any sense.

It's incredibly padded. Mastering the power of the golden statue, it's absurd that a Demon Slayer story could have so many chapters. That era was one of extreme admiration for strength and worship of gods; why waste time on Muzan? The protagonist could have been like in the first Nexus episode—one punch of light to finish off Muzan the moment he appeared, then he could have been treated as a god…

The Fourth Hokage, Hiruzen Sarutobi? What, you watch Mizukage too?

This is so boring, it's a mess, super filler, and the protagonist keeps saying he's afraid of trouble while making things even more complicated, it's so contradictory. He could have just pulled the Demon King over and dealt with him directly, but instead, he keeps saying that's too much trouble while pulling in Yoriichi Tsugikuni from hundreds of years ago and then getting bogged down in a long…

The protagonist is such a jerk, using the same abilities as the Oscar statuette and ending up in this mess. Tartarus seems to have been tainted.

Whether it's overpowered or not is another matter, but in the Demon Slayer final battle, Hinata should have easily defeated them all. According to the power levels in Naruto, Naruto and his friends were just playing around with Mach speed when they were in the Ninja Academy!

It's so boring. Their power levels aren't even in the same league. Why waste so much time on a broken Demon Slayer, playing house with a bunch of ants? It's unbearable.
