A brief description of the manga Ichioku-Nen Button O Renda Shita Ore Wa, Kizuitara Saikyou Ni Natteita:
A boy, Allen-Lordle, who is despised as “Rakudai Kenshi” by his surroundings. One day, he decides to leave the sword arts school and duel with his classmate, the genius swordsman Dodriel. While despairing for an unwinning battle, Allen happened to get a “100 million year button.” !? It is “one hundred million years pressing, bound to the world of the time,” was the button cursed
However, it pummeled him one billion years button that took advantage of the fact, a dozen million years also of the End of study – I learned the ultimate sword skill! After that, Allen overwhelmed Dodriel and had excellent results at the swordsmanship competition. Furthermore dive is talk of recommendation admission from the swordsmanship of the prestigious “Senha School”!?
Now fail swordsman in hand the strongest force, its name to the world Todorokaseru!
Pretty low tier near garbage.
– Bro went “100M” years into time chamber and only reached the entry level of swordsmanship;
– It’s a wild copy of Rakudai Kishi, Jujutsu/Naruto, Black Clover and Gakusen Toushi Asterisk, he starts as the lowest one, have a ridiculous body strength in a place where it is kinda secondary (Really, it might not be that apparent before they introduced “magic swordsmanship” in like… chap. 12? before that it was only surreal swordplay), MC have an “evil” (most likely just chaotic) entity with near infinity power and regeneration and they gain a tattoo during the possession, they can summon swords and otherworldly ‘soul’ spells and there is a seal involved, up to 29.1 we only know that he had a seal in his body that reacted with his emotions;
– Fire users as main lovers/heroines, cliche opening the door and undressing heroine right into a duel and surprise, she is a princess of some random country;
– Oh, did i mention that he is unable to use the inner entity power? But it can go rampage randomly.
The only up thing is that girls have a pretty design and a lot of fanservice, so this point can be also a negative if you are not a fan of random nakey body flash.
Lazy ass manga forgot that the human brain can only handle 450 years of memories
this is why i hate numbers in certain manga… 100 million years… 100 MILLION YEARs… not a fucking chance in the universe you don’t go braindead being alone for 100 MILLION years, they could have made it 1000 and it still wouldn’t match the struggle he still has fighting not masters but other students, in fact you could have just made it so he had a 10 year button and could press it like a hundred times so his level of struggle might make some sense and he could press it in battle and train for 10 years to overcome that situation and maybe that would make a little more sense, but anyways like 0.5/10 and that .5 is only because despite the tropes and cliches absolutely littered in the plot it had a small sliver of being a bottom tier boredom read until he pressed the button and it all went to absolute shit. please for your sanity steer clear.
Why are you gay? 
1/10. Starts out in a semi-medieval fantasy setting with european architecture and just goes to basically modern day japan but with swords and magic when the main character travels to the city (this happens in the span of like 5 chapters).
Actual slop tier manga with overly busty school girls and an obligatory scene where mc accidentally sees one of the fmc’s naked, he then for some reason gets roped into a duel with her which he doesn’t even try to decline and she ends up as his “slave” for literally only that chapter and it’s not mentioned again. After his win (obviously because the author has no better way to develop the plot) the mc’s 100 million year old virgin ass ends up seeing her naked after she comes out of the bath (this is the second time it happens), blushes again and scurries to avert his gaze.
I couldn’t get past chapter 9 because reading this shit felt like an actual chore with extremely overused cliches. The only way to enjoy this slop is if you are a 14 year old teenager going through puberty and experiencing hormonal changes or a stereotypical brain dead coomer who only cares about jerking it to anime girls.

I had a stroke reading that synopsis
2/10 (read till 3.1 during this rating)
At first it had quite a bit potential damn did it get bad fast. The mc pressed the 100 million button but guess what he only trained the sword and didn’t go crazy.not only did he not go crazy his mental strength is still weak(unbelievably weak).And you had 100 million years man, at least learn the other qualities you’ll need like cooking,woodworking, blacksmithing etc. He also isn’t that strong considering he trained 100 MILLION GODDAMN YEARS(during the tournament at the finals he struggles).Well I only read a couple chapters(3.1) so maybe just maybe it might get better. I’ll send updates by replying to this.
Uhmm the story has a lot of potential but wasted due to the MC doubting himself too much rather I would say and one of the reasons is being too bright I would rather say like the Uh Girls or I Dunno they would be some kind of mascot and also it appears they have abandoned the concept of Thousand Swords School and many factors to be considered.
I Rate It 2/10
holy sh*t! whoever wrote the description is a retard and some of the readers sound like just as illiterate ‘tards…
“Kid that is a bad sword press button”…
“yet somehow still looks struggled whenever he fights”
Short version: Kid that is a bad sword press button to train in a sub plane for 100 million years to become stronger and is still ASS.
This shìt pisses me off, so he was stuck for 100 million years in a minor sub plane(it’s not 1 million, it says 100 mil on the manga) so he swung his sword at least 99 million times, yet somehow still looks struggled whenever he fights. The normal weight of the sword he uses is around 1500 grams, not only that, it’s a world you get powerful with training with no known bottlenecks so you can keep getting powerful as you train more, scratch what I said earlier, he probably swung his sword roughly 200 million times because there was one scen where he sliced the pole in less than a second, he sliced a pole in less than one second and he can’t slice of steel from swords or do high speed attacks/barrages, he also mentioned he made his own skills and his skills can’t even break a sword of a whamen who trained for less than 15 years of age against him who stayed in a pocket dimension for 100 MILLION YEARS with his more intense training that saitama.
What the fùck author you made me do math.
6/10
The story was good and the plot events, in my opinion, was written well. It wasn’t boring in the least. My only problem was the MC.
I’m sure I’m not the only one who noticed but a problem with overpowered MCs in manga is the fact that they are not self-aware of how strong they are, which is pretty annoying. I wouldn’t mind if they become strong and at first, they are doubting themselves, but it gets annoying after like 8 or 10 chapters. The MC was training after 100 million years, if you don’t have any self-confidence after 100 million years, you should just put down the sword. Although we do get to see some side of MC getting confident and even taunting his opponents and what not, it just felt like it was a little late being that there aren’t that many chapters which is disappointing.
Another thing that bugged me is that how the MC isn’t overpowered after 100 MILLION years of training. I feel after that long of training, it should be a piece of cake competing against other opponents. Unfortunately, we see him struggle pretty much all the time. I do like the idea of main characters not being overly overpowered, but with how the main character is written in this, he should be overly overpowered after 100 million years. If not, it just doesn’t make sense.
Anyways, the story itself wasn’t bad. The side characters didn’t feel annoying, at least for me. It was confusing though because I have no idea what era it takes place in, I assume it wasn’t modern at first because of the usage of sword and other things, but then bombs and other things was introduced so I have no clue.
Lmfao you can tell this is trash(I never call anything trash) by the summary. If you are training for millions of youre, then you would be god level. Anything less is a joke. You would also be a good amount insane.
