Ore wa Seikan Kokka no Akutoku Ryoushu!

The story is very good ; and feels refreshing from the generic similar story ; I like the influence and reverse story turn-over from the negative dude to positive side ; if you are not looking for anything specific and just a good Isekai story.
The story - feels immersive and good for watcher ; take the story at face value ; for what it is ; not for your 10+ million experienced similar Isekai story ; you can say the same for any genre that have exhausted the formula for years.
Audio - voice acting feels a bit forced ; too much exaggerated voice acting ... in some respective cases ; that ruins the immersion for the watcher I feel ; sometimes a bit less is more immersive and better then too much over-forced acting.
The world development and characters are great ; really gives you a big picture of the whole world and story ; as well as the character development and interaction.
I would prefer a more detailed MC growth expanded story where expanded on the character development not skipped time for that with results showcase.
The plot and story wants to develop in a more mature plot ; but it goes back to being afraid of showing to much mature action and turns into a 12+ years Rated anime ;

I feel that this could have become a good mature anime contending Chainsaw Man if it had the courage to not be afraid to develop the story in a more mature action & plot

While watching the latest episode, I had a moment where I thought, “This anime could actually be great if it committed to pushing the story forward.” But then I asked myself—is it even trying to be a story-driven anime? Maybe it’s meant to be a comedy? I checked the genres... and surprisingly, comedy isn’t even listed.

That’s part of the problem: the anime doesn’t seem to know what it wants to be. It’s isekai, but the main character doesn’t do much with his supposed knowledge from a previous life. It teases mecha elements, but there’s not much focus there either. The harem aspect? Practically nonexistent. And ... while the setting is technically in space, it barely uses that backdrop in any meaningful way. Action? Fantasy? Kind of, but again, only on the surface.

Ultimately, this anime feels like it’s trying to be everything at once and ends up being not much of anything. It’s the kind of show you can throw on in the background, and while the art style isn't bad, the lack of clear direction makes it hard to stay invested. Instead of doing a few things well, it tries to do ten things and ends up mediocre across the board.

I was really hyped the moment I saw this one getting adapted. Having read and continuing to read it when it gets updated on narou I'm what you could consider a fan, but this anime is simply awful.
 
The original version is the narou's one. The author was actually making a break by writing it.
The lack of an actual roap is felt all along but each arc is actually structured and interesting, making its success unsurprising, as the author being knows, he already had a fan base.
 
Then it got the published novel version. I didn't read it, though I do have read enough to know ... that narou works being published are... A bad thing.
The whole point is that they add parts to make it interesting for the original fans, but success is fleeting and making a new story is a no-do. So those news parts are unimpactful even when they should actually have some consequences, turning them into a complete loss of time.
I had some hope with this author, his success not being simple luck but actual skill, having others work adapted such as Seventh and Otome Game Sekia wa Mob ni Kibishii Sekai desu. But, hope is just hope.
 
Which brings to the manga and after that the anime, which happen to take on the manga sometimes rather than the novel, making it an adaptation of an adaptation of an adaptation of an adaption. Great, I'm sure you can feel the improvement of each step, but... Well, copy/paste actually degrades the original.
 
Now, onto the actual anime. There are 3 things that completely killed the original charm of this work.
 
The first one is the pacing.
The story begins with the Mc fighting then go back into the past to explain how he came to this point. This is a usual trick when the beginning is slow, making an action part that makes you want to watch it so that you stay here while its more boring part comes just right away.
I, didn't like it, because it was cheap and not interesting at all, but even so, I thought that it was used at the beginning only and then there would be the actual story.
But they just kept on going with this dumb pacing, replacing the action part with what was happening to another character in the following episodes.
It is a stupid move because not only it breaks the pacing, but you don't event know the character so... You don't care.
Oh, and it is also a boring typical development so, go luck to even care.
 
The second one is the past of the Mc.
It takes the whole first episode. Does it need to take that much? Is it interesting enough to take 20 minutes? No.
The narou version actually nearly skips it, it is just an introduction after all, a typical way to show how the Mc became like this, you don't need the day.
The anime version though, is sluggish. Nothing to do with the actual story nor anything and yet taking the whole episode. Not only it is bad, but it did worse by changing what happened.
The narou version was slow but it was mentioning how the Mc found his wife lingeries becoming daring, her changing her appearance, some little steps hinting at her cheating in his everyday life. It showed that it was actually a true possibility, having the husband finding small changes and finding out too late on one side. And a typical wife having a hazardous meeting with a bad boy that changed her and broke her life then ditch her out once bored on the other side.
When you learn why it happened, it is logical because just a bit of misfortune can make such a misstep happening.
Now, the anime version though? The wife is just the same, not getting gaudy nor anything. They made his child not his child for whatever reason making the whole cheating story long of at least 7 years. Because of those changes, it isn't just a misstep anymore. The Mc simply wasn't looking at his own family for at least 8 years. How the hell can he be allowed to desire any revenge when it feels completely like his fault? This is simply stupid, borderline comical but they did not try to make it comical.
Let's add that the other guy seems to want to actually marry his wife after it, making it an even more average relationship trouble.
 
The third one is the Mc.
Now, you'll probably don't get it. Even so more if you watched this anime.
The Mc is great. Seriously. The guy always seems pissed off, he doesn't talk much, is straight and full of himself when talking and acting. All that because he has trust trouble coming from his previous life and decided to live for himself. The whole success of the original work comes from him.
The Mc of the anime though? He's just Mc number 19052462. All his reactions are those of a typical Mc. Overreacting, not thinking, having a change of expressions at each sentence, like every other Mc. The guy is boring, They made him the usual Mc. Making the whole work having its charm taken from it.
I know that many have liked the sentence part in the third episode, but it wasn't that long originally. He knew that someone was making use of him and just sentenced, no whole excuse with a traumatizing past scene in it, his past was already talked about, and as such, his choice already explained. That just made the whole scene flattened.
Even the whole Yasushi comical parts became longer and dumber.
What's even the point of looking at his prowess if he isn't someone badass anymore?
 
As I say, I was hyped about it and am a fan of the original work, but even for a fan, it was just a boring bouncing around average isekai.
Kind of hard to say anything good about it.
