This author probably has a few screws loose and not in a fun way

by Seregosa

By the title, I mean that this author is ruining his own work, contradicting the initial setting and just screwing himself over so big time, it's hard to watch. Any reasonable author would just axe their own work and move on to a story that they ACTUALLY want to create now instead of staying with the original, instead creating plot holes and flaws all over to the point it becomes unbearable to read.

I read about 130 chapters but started to get fed up at around 60-70 chapters even though the chapters before that was pretty fun to read. The protagonist is a hypocrite, doing dangerous stuff and making irrational emotional decisions 24/7 but then gets upset when some other character does the same (like the knight who wanted to die for some short time benefit for her kingdom, calling her stupid and being pissed when he does the same thing all the time).

The start was fun and it kept to the original spirit and intent of the work. He was supposed to be a funny, hyperactive and silly yet overly skilled loner, both from his own will and from the job/skills he got with his transmigration, one which literally makes it impossible to form a group, or it should've. But after the initial bit of silliness and fun, he becomes a typical shounen protagonist, by that I mean utterly god damn insufferable.

He helps people for no reason, like, literally everyone he comes across. A spy stalking him? Yeah, save her and help her with your life on the line. People who treated him wrong? Help them. A knight coming to screw things up? Yeah, be all apologetic about something that she brought on herself and then "rehabilitate her" and help her get out of depression. Random people in the city that never asked for it? Re-build all their stores and houses, although you don't even know them. The entire city needs to be babied and helped along.

He gets all sad and saddles himself with the responsibility of the city he first arrives at along with all his classmates. He gets used heavily and does his best to save everyone, no matter how small their connection. He gets all upset because one classmate ended up on a rampage and killed some delinquents, pure trash human beings that has proactively tried to rape the girls over and over again before being offed, he actually gets SAD that the bottom pit of humanity gets killed after repeatedly committing crimes of attempted rape and murder, the kind of guys we're supposed to LAUGH at when they die. Of course he also never kills humans except for a select few, because he's some sort of a super saint that has no shred of REAL humanity in him.

Once the drama starts, it just gets worse and worse, so incredibly fake and forced and the whole "loner" thing is at most used for tiny "Gags" here and there where he pretends he wants to be alone to do his own stuff but gets pretty much imprisoned by his classmates, especially the girls (calling him a doormat is a bit too kind), and he spends all his time with other people, helping them and grouping up even if the author likes to claim he's not "doing it on purpose" as he helps them level up, farms/creates gear for them and is just an all around goody two shoes pushover that gets used by everyone and is happy about it as he has no desires anymore except to help everyone else than himself.

This story is awful because it disguises itself to be something other than a normal shounen love and friendship trope piece of trash that is meant just for kids. It's rare to see a story where the author so quickly betrays all his own setup and world building to make something horribly bland and generic. 4/10, I'd rate it at less if not for the first 60 or so chapters being decent enough.

It's ok until it's stupid

Starts ok. Interesting idea. Then it turns out he can just learn things waaaay too easy. And the dialogue and developments and such just become waaay too stupid, especially from the final fight of arc 1 onwards.

Started really great, but then falls-off with the generic isekai trope

by Utamaru

Rating: N/A

The series starts off quite good, where the MC were transported to another world with lots of underwhelming skills (e.g skills that makes him stronger when solo), and he tried to survive in the harsh world.

But then everything takes a 180 turn when the MC helped his classmates from danger, and they decided to stay with him, since he's strong and dependable.

This plot point literally throws away everything that happened from the first chapter, where he supposed to be living alone/solo, since many of his skills clearly mentioned that he can't form a party, or even interacting with others. And yet he casually can interact with his classmates, to the point that he created his own harem.

I don't know if this problem will be addressed much later in the story, but I really doubt it, and I don't want to force myself to read another page of this shit series, which is nothing more than your generic harem isekai manga with somewhat OP protag...
