Nice, really nice.
I like this story, because it's honestly different, i seen so many that want this story be a carbon copy of every isekai cliche, and they become absolutly unable to understand the message, or the story, and that's sad because they become one of the most dumb and boring cliches, the Fans who demands something to be different to mainstream products, but hates anything that it's really different, and demands to be just like mainstream products.
This story it's about someone who's main goal is to protect the know story, why? mainly because fears the consequences of change, it's like Doctor Who and Fixed Points of time, it's not that it cannot be changed, it's that if it's changed, the consequences could be so bad and painful, that those points have to be protected, and of course, those who don't know about consecuences, can't understand why.
This kind of story with the MC really walking as much outside of the main story as posible and only acting to protect the main story it's absolutly genius, it's such a very hard way to tell an story whitout a god like observer, and of course, the main danger, is the fact that uneducated readers, won't be able to understand it, so this kind of story, it's usually more a passion project than a mainstream product.

So, is this an End end, or it's just an End to restar with an R or an S, or maybe even a Z?

Don't know why, but my brain started repeating "Save the Cheerleader, Save the World" XD

Nice scene, remind me good old Literature based Animes, where animation didn't matter, but the power of the Words, and the Voices, reading this using some powerful dramatic voices really gives that delicious Detective/mastermind confrontations, good old times, good issue.

Kids these days, obviously, a dramatic confontation, it's too much for you undeveloped literacy sense, go read Naruto or One piece, that's much more on your level.

I love how in perspective, this was a clear sign of how much Koki hated Nagumo and Evied he's power.

well, i think we still have to find 5 other dwarfs, i mean Nobbleman XD

Remember dude, you are basically a Married Potatoe XD

aahhh, the chatting girl just gossip about the slime hunting method, well, i was wondering when that will happen.

So, they gonna do some minecraft XD

naah, he was the scruffy of the fantasy world XD

Well this is surprisingly good.
The useless OP MC it’s a subgenre of Fantasy by this point, sadly, usually force characters to act in a completely stupid and illogical way, i mean, how can a country be really powerful if it doesn’t take care of the details, an army moves by it’s stomach, any real conqueror knows that, a kingdom can’t work without towns and people working on them, and in this case, a magical powered empire, cannot work without people creating magical items, so rejecting someone you need, it’s really stupid and illogical.

Fortunately, the author take several good decisions, including, playing with the Isekai concept, without using an isekaied MC, The story has a great flow, very few slow parts, the MC is OP, but i have to say, he was mainly useless before the story started, the author kinda retconned that fact later, but it’s really forced, i’m more comfortable with the fact became OP basically, by luck, perhaps because the MC it’s a learner, he is constantly learning and using the new info to create things.

The isekai portion, it’s more a lore of the world, and i just love how the people of the land, MC included, have no clear knowledge about the isekaied people, or the things they left behind, and have to use a far from perfect explanation, extrapolated from what they can understand, or imaginate, it’s fun because we do the same with things that are too old XD.

The Art it’s Very Good,the character design looks familiar, but has a good self sense, so even when the characters look like other more famous ones, still separate from them, the flow of the art it’s very good, and the expressions are believable.

This is a very recommendable manga, for those who like fantasy stories, even if you are tired of Isekai stories, because as i said, the Isekai aspect, it’s more background and lore.

Well tbh he was pretty much useless in the human territorio, due the lack of OP energy

I definitly got Spiderman Blue Vibes, reminded me how Gwen Stacy helped Parker to keep he's identity hidden, well, untill the Bridge incident, hopefully, that won't happen here

Well, this one it's good.
Reading the first arc complete it's a great help, because there are several dumb moments, also the art it's not awesome, so waiting a month betwen issues, most probably make people just forget about this manga.
In escense it's a very very standar Isekai, very standar almost Mediocre, what helps the story is the fact that the MC it's a thinking person, the kind of people that analize a situation calmly and take the best way, and yes make that analisis and descition, in a few moments, Also, the realistic approach to damage, exhaustion and effort, also the honest reaction of the characters according to their age, it's very refreshing, and makes an interesting reading.
Sadly it has many faults, the characters design are way too cliche, way too i see that before, easily forget them, including the MC, also the art, it's nothing special, just average manga art, so it's really easy to confuse it with other mangas.
If i have to compare it to something, i Say this is Isekaied Spiderman, the old Ditko, Romita, Buscema spiderman, where a youngster has to help people and save the world, while hiding he's powers and identity from the world, and perhaps the best part, it's an spiderman with the Gwen Stacy of Spiderman Blue.

not bad, kinda slow for a climatic battle, but not bad

Going to the Darkside? Seems like mom it's gonna have to use the Chancla on the MC

Fishing in open sea it's fun, when i was a kid, i go fishing in the ocean, but not on a big boat, on an small one, a Lancha, and we didn't used any rod, just a line, your hands, some cupper weights and of course bait, was fun, a friend of tha lancha owner was fishing for octopus near, he just dived to the bottom whitout any tank or mask, just a knife, good memories, except for the skin sunburns XD

If this is the end, it's a great way for end this story, love this reading so much.

Japan loves the Coronel So Much XD, it's not like we don't like KFC, it's just, it's not as tasty as it used to be
