Well, I don't know yet if I liked it or not... I confess that the first chapter was a bit cringe, although I liked the idea of gender swapping and a dramatic, exaggerated personality, I found it very generic and exaggerated, like the beginning with the bad guys attacking a girl and then suddenly it seems like they're best friends and need each other....... Is he going to do this to every random person he saves? Because that's what it seemed like.
Update: Ehhh 6,5/10. Not exactly "bad", if you want a silly story with no particular purpose, just to pass the time, it's okay.
But the story seems like just a self-insert; I even enjoy a story with an overpowered character here and there... But he's just a empty guy, without any purpose, who decided to be the biggest simp in the world for the first girl he saw. There is no development at all, on the 2nd/3rd day they already look like they're getting up to mischief in the bathtub.
He's overpowered but doesn't care about anything in this world. He could take down villains in seconds, but he seems to enjoy letting them swear/do a little evil before really acting... I know it's for the manga's purpose so it doesn't seem empty, but it makes it seem like she just likes to wait to act like a heroine
