So, are they just not going to address that the prince also tried to murder his opponent while their back was turned after losing the dual to them?
Like yeah, MC is a commoner. But it was still a public event, and MC is pretty famous as an asset to the kingdom. On top of that, now the MC has complete justification to directly be against the royal family while again, being a a notably powerful individual that other families are already trying to bring into their own militaries.

I can't wait to see the reactions everyone on the outside has.

So, heads up.
It's an interesting premise and has promise, but it's told in a really crap way in the first 2 chapters.
What I mean is that it starts with a young MC, and MC starts telling a story to his students, and it jump cuts to MC as an old man as if it was in the past, but it's actually the future, and older MC starts thinking about something bad that happened to the students in the past, which implies that it happened after the initial part of the story which was set in the past where the students were okay, but it's actually before that part, and another character points out that he literally solved the thing he's regretting and was happy in the first part, which happened after the third part, so it literally makes no sense why he's so down.

Basically, the story will be potentially great once the author gets his shit together. Hopefully that can happen in chapter 3, so that new readers can just skip them and get a cliff note version.

Read up to 26. And yeah, It sucks.
Firstly, the description is wrong. He didn't travel into the past, he traveled to the future.
Secondly, the series works on nonexistent logic. The teachers are against rule breaking until they aren't. They're all D-bags who punch a small child for being distracted, until they aren't. MC is weak until he isn't(but don't worry. He didn't have to work for it), and his logic for not telling the people that he's the legendary figure from the past and has super crucial information on their enemies is because "It'd be a hassle, and they might not believe me."That's the savior of humanity guys. He doesn't even evolve! He just steals specific powers from the demons he kills.
And I know the other comments say it gets better, but I honestly just didn't feel any investment in the characters or the world. So I'd give this a pass personally.

I think it's because even if they couldn't have succeeded, they still officially failed miserably against kids. So if he let them go despite failing, it'd look like he was being weak by allowing excuses to justify failure, on top of these people potentially gaining resentment as a result of this incident(whether it's towards Helmut for making them fail, or towards the organization that sent them on an unreasonably difficult mission disguised as an easy one).
So getting rid of them wasn't because he didn't understand, but because he was trying to prevent any fallout from their failure.

Summary:It's like the Wish.com version of Wise man's grandchild, with a ripped off speedrun of the piggy duke premise.
Art isn't bad, but kind of bare bones in every other department.
That being said, the "rival" is just pure bad writing. Like, this child is just the most cliche brat character, but also openly commits crimes against the most important people in this world(including attempted murder) and should've logically been publicly executed twice as of chapter 13. And it's not even like the series makes it look like he gets away with it. The dude gets caught, everyone calls him an asshole, and then everyone just forgets what he did.

Worthless regression

So, now MC personally has the skill to nullify 99.9% of damage he takes. Right?

You dont seem to get it, so let me ask this. How much is your life worth? Let's say I rescue you from a burning building and save you, and now you owe me. What can you do to ever repay me? Saving my life is most likely never going to happen, so how would you ever repay me for what I did? Nothing you have to offer me is useful, but I literally saved your life. Sure, I may say I don't care, but literally every moment of your existence, every breath you take is a result of me going out of my way to help you. What could you possibly do to return that favor to me? What amount of money is worth your entire future?

The problem is that your version of kindness is unreasonably cruel at times.
Having an unpayable debt(especially out of charity) to someone weighs heavily on the mind and creates feelings of failure and insecurity(which DOES lead to suicide occasionally).
Whereas having a debt that you HAVE to pay back gives motivation to work hard, and get back on their feet. So it's almost like getting a second chance.
The problem is that you're looking at it very very very surface level, which kind of makes it into the "give a man to fish vs. Teach a man to fish" scenario.

Summary after the first 30 chapters;
Not bad, but also not my cup of tea. Basically, MC is constantly running into victims of power abuse and the police are constantly always 100% corrupt/bought out so MC constantly has to throw legal jargon to get everyone to stop being so evil, because corruption and power and all that stuff.
Honestly, MC is pretty good. He legitimately thinks ahead and plans using his lifetime of experience, which is a huge plus as opposed to him just magically being the best.
That being said, the story runs on Twitter logic where basically anyone the MC gets along with is good, and everyone else in the world is stupidly eeeeeeeevvvvviiiiiilllll. Like, seriously. MC will literally just walk down the street and suddenly save some random elderly person from a porcupine molester whose father is the president of the police bribery company(obviously didn't happen specifically, but you get the idea).
So while it was interesting at first, I just got tired of the same "everyone with power is corrupt!" formula over and over again. That being said, maybe you won't find it so repetitive. This is just what I felt while reading it.

It wasn't until reading your comment that I realized he wasn't saying "God d%mn" in a funny way, and instead quoting some internet trendhttps://i.postimg.cc/FsVwTzw7/i.gif

Never thought I'd see Yoko Taro making a cameo herehttps://i.postimg.cc/Vk0fRLrQ/i.jpghttps://i.postimg.cc/pLmT6JSS/i.jpg

MC probably SHOULD break up with the girl if all their relationship amounted to was just 1 canceled trip. Especially when she knows him being busy= him saving lives

Ehhh/10
It's not offensive, it's just kind of generic and basically follows the exact same plot as all the other "summoned alongside the saintess" stories with 2 exceptions.
1. everyone besides the love interest are just complete assholes to the mc because... she exists? No conspiracies or misunderstandings they just hate that she's there despite her not asking to be there, not doing anything, and just wanting to go home.
And 2. The story got axed so quickly that the saintess isn't in the story. Like, I'm not even joking. She shows up twice because the MC happens to run into her, she never says or does anything for the entire series, and she just doesn't exist afterwards.
So it's basically just a meh quick read you'll probably forget about once you start reading something else.

Honestly was kind of hoping he'd reappear like this.
