I think the author is terrible at communicating anything to the reader. Univas's goals and actual actions are often at odds but I feel like this is particularly egregious. The only reason he was going to the adventurer guild was to get a job to make some quick money to buy food. Ignore that they were just at the ocean and could've just gotten some fish there. How long does Univas plan on staying in this town? They gave him the worst paying job available. Doing this job will likely take quite awhile to accumulate the funds necessary to buy all the food they need to continue their journey.
Is there really no other avenue for him to make money? Could he not just hunt some animals and sell the pelts? Cause it makes him look like a moron to just gladly eat the shit people throw at him when it seems like there are better options available. Honestly it feels like his whole journey doesn't actually matter and he doesn't care about it. He has no urgency whatsoever and is constantly sidetracked by stupid nonsense. People keep materially getting in his way and throwing roadblocks in front of him but every time he's just like yeah whatever doesn't matter. Does not give the impression he really cares that much about fixing Trans.
When it comes to his goals and actions he clearly knows the receptionist at the guild and she has some lopsided idea of what it means to be appreciated and cared for as a spirit: we can see this using her disregard of spirit the princess’ outlook on univas as speaking to her stubborness to anything contradicting her own feelings; the idea that a “famed” spirit user is proudly depicted with abused spirits; her being a gold spirit, and the story of Univas’s hair being previously gold before it was recently dyed at the beach means that if we take the path the hero’s party took in reverse she saw his golden hair originally and the dying may feed into her dislike of univas (obviously tinted by the hero’s lies); as well as his words “but means you’ve been accepted here.” All of this points to some failing of Univas’s which he feels some kind of attachment to and will be resolved by the end. He is a character guided by feeling and gratitude, so the thought of it taking forever to earn money is literally not something that crosses his mind. It’s a well-earned savant reassurance that things will turn out just fine so long as he can go and interact with the spirits. Every time he has been sidetracked it has involved spirits: in large part as long as the spirits, wind in Tifon, Earth in Trans, Water in Izumi, along with the countless members of the wind water and soon to be fire lands are happy then he is content at this speed. Trips that should take days or hours are reduced to minutes by travel speed, he has already made trans better by fulfilling part 1 of his plan to remove the engraving, and never overstays his welcome despite EASILY being able to spend two or three times the length in any given area. I legit don’t know where your feelings are coming from, but his character is to endure, remain steadfast and kind, then be rewarded for it.
So within the span of a single month the hero has lost nearly 800,000 positive impressions in the total population of his fame, but in that same time MC has only managed to gain about 63,000 positive impressions? I assume he gained all those within the last month as well since that's how stupid this manga is - absolutely nobody in the entire universe liked him, not even any friends or family (if he has ever had any?)
A Charisma of 1 is so over-the-top, even when trying to go "no it's just in reference to humans!!!" that's just way too low. We're talking someone with so little ability to communicate with other humans or influence them that he might as well be nonverbal with any human he comes across. Like the people of this world are likely to be friendlier with actual monsters than the MC, it's ridiculous. To be fair, nobody ever listens to a single thing MC says and he just rolls over and takes it anyways, so maybe the 1 Charisma is more accurate than it seems.
Yes if you look at how things are changing, Univas has made overwhelming splashes but in very specific areas: a town here an island there, a beachfront there. Word in all of the major areas has either been in relation to the incompetence of the hero’s party, but the ripples of the splashes have yet to move outward. Warswamp still should be in “chase Univas” mode, seeing as before he arrived in the areas where Univas had done good, the government was still under orders and the belief that Univas had ruined a marriage and tarnished the love of the hero and Tifon. Even the Gold spirit at the guild says “I read the newspaper”, meaning the current news is STILL speaking that lie. Once Warswamp returns and announces the horrendous untruth of the “Hero’s Festival”, word of Univas’ greatness can spread, but in this world word still travels slow. Yes it is the trend of this manga: literally nobody likes him because propaganda has taken root and any given person will believe the word of the “Hero who stopped the demon lord”.
As for the Charisma of 1, it makes perfect sense, Univas is only able to act properly now because he is constantly being validated and surrounded by Spirits that people can actually see, but go back to Chapter 1 and see how he is acting there. THAT is the kind of person he was behaving as for THE ENTIRE DEMON LORD CAMPAIGN, in relation to the one month where everything has done a 180. He was described as not having talked to any of the other party members and instead only talked to the magical items that contained spirits for all that time: it’s consistent, he is that bad. Not only that, but it’s been consistent in the story: he has never confronted the actual people in the towns that hate him, but beelined to the spirits and had them do all the interacting. He has been told “come her the spirit wants to talk to you” or been in situations where spirits have outnumbered humans, or literally had the overwhelming reaction of the spirits/the world speak for him, but in the story he has shared barely any direct sentences with other humans. He IS that nonverbal. Once again, you’re right but it fitst the world and characters that have been presented. So far to a tee.
Edit: it also occurred to me that the “Luck 1” is nice writing, considering that, for an MC, his success has been self-made. He asks for things and because of his history of respect and good deeds, he gets rewarded. He comes across these places not because he stumbles into them, but because he has them on his journey. You can’t even say that coming across the island was luck because he was carried there by the water spirits, already knew the place, and was imprisoned within seconds, but made the best out of a bad situation by taking action and kindly asking his resources for help. Since the spirits all have will, even that can’t come down to luck.
