It is especially made apperent in my opinion when in a short while the MC is shot at by a bunch of arrows by archers but doesn't do anything to defend himself because he's about to fly away, even though he knows multi + insta casting and the highest lvl of wind magic, instead he just watches the arrows until he is hit and then runs away and then dies cause apperently all that kingdoms solider have all their arrows dipped in a slow acting poison that instantly kills a person all of a sudden. But luckily the MC had a ring of life substition so he instantly revives but loses his extra life ring.

Then some chapters later he captures heroine + her harem but then one of them free's himself and charges at the MC and then almost instantly kills the MC cause he can again do nothing but watch himself being attacked. These two parts in short succession just feels way to forced especially up to this point we've been told the MC is lvl 40+, if I remember right, knows a ton of overpowered skills and has the best gear + guns while the heroine + harem are all said to be around lvl 1 and super weak and get's instantly defeated by the MC but this time it get's explained that one of the harem members used the super powerful hero buff. So even though the MC again is a much higher lvl which also grants him a much higher strength + magic stat just because of a buff (that was never even mentioned before this point even) the lvl 1 harem member becomes so powerful the MC can't even react before he is pretty much killed and only survives because the villaness puts him in a coma in holy ice.

Honestly these two parts really made the story drop in quality in my opinion especially since most of the story up to this point was about how much the MC works to grow stronger and has gotten so powerful he can face armies alone and pretty much fight dragons in melee combat. While the heroine + harem on the other hand has becomes super weak because the MC has been stealing all their powerup chances + the heroine is super lazy and doesn't even bother to go and fight monsters to lvl up or use her skills to become stronger and instead just goes with some kind of happy go lucky mindset that everything will go her way just because she's the heroine so she knows, or at least thinks, she has a too thick plot armor to even fail. But then from nowhere they become stronger then the MC with no effort or reason what-so-ever??? Like what was even the point of reading the 70-80 chapters before the end part???

in the first part since recovers the memories he starts going in a stregthing spree like every MC, then there is the secret equipament that he creates, a plane, but you can get away with that since in the first chapter the author says that he is a plane engineer, and gets the wind god blessing.

so he stars colecting a lot of cheat skills, spends 4 year training, gains the ability to create cheat items like a plane, and use magic.

so in his first real battle can you believe what he does?

he turns the goblins in beehives with a ak47 the stereotype gun of all novels gun otaku!

like there was nothing at all that leads to this! no development! no trial and error! no past! and no clue! the MC just sudenly has the lovable ak47 after 4 years of training and raising funds. and just as suddenly the MC now is a gun otaku that wanted to be a pilot and trained in war zones? cmon !!!

author why did you make the MC train for 4 year stregning and collecting cheat skills if you are just gonna make him use a gun! and after he got the gun he stars cmplaining that is too weak and starts devoloping? haaaah....

I enjoyed most the developments in story, however in the ending afterword. We get to see an R15 perspective of Amy's passing. I know the author finds it hard to write her character but it still shocked me that her last words had to be that depressing?!? Okay I feel bad for her but she still deserves it. Which made me think Author should have written about Amy more and developed on why she behaved so childlike be it a past life trauma or others. In short she was not fully developed and used as a "villain" plot mover

It might be fulfilling to end on a better note to make us readers hold it dear, but hey this is an after story

The Heroine Turned Villain: She is pretty f*cked in the head and she ends up getting r** until she dies by Mine workers because she was sentenced to be a prostitute. I mean, it wasn't bad but the author seems lazy about the whole story and refuses to write details and go deeper into any topic. Now about the rest of the entourage, the Prince of the main Kingdom/Karl or whatever his name is doesn't repent until the end and gets off pretty lightly, he refused to believe Amy has in the wrong even after the Brainwashing was released and was sentenced by his Brother to home arrest and doesn't leave his house anymore. Prince Claude of whatever Kingdom he was from gets scott free from everything. After losing the duel the motherf*cker just peaces out to never be seen again if not by two brief mentions. The Knight Leonardo dies. He was brainwashed and sacrifices himself so Amy could escape. Oscar gets released from the brainwashing and "is ashamed" and returns to his normal life because Annastasia is such a saint oh my god I could tear me a whole brand new an*s because of how amazed I am by her generosity to someone that could have ruined her life. Markus sacrifices himself to protect Amy from a point-blank Saiga shot, but then the OH SO AMAZING VILLAIN TURNED HEROINE BECOMES A SAINT AND CHOOSES TO REVIVE AND PARDON HIM FOR HIS PAST TRANSGRESSIONS AND GUIDES THIS POOR SOUL. Sorry, he just gets revived>apologizes>pardoned, nothing that dramatic.

it's actually surprisingly dark given the tone of the rest of the story. Like Amy deserved to get sent to the mines as a who*e but holy sh*t a first person description of her losing her sanity and dying to STDs was not something I expeyto read. At that point guillotine-chan is just the more humane option.
