MichaelAtlas basically hit the nail on the head with the comedy being great but working against the story when it tries to be serious.
I normally would rate this an 8/10 if this was only a comedy, but it's not, and the protagonist being so dimwitted, combined with the insistence on stagnating literally everyone's relationships (with the main character and each other) in order to keep up the gag, drops this to no higher than a 6. I'd argue a 5.
Not to mention how ridiculous so many of the conclusions to the various plot sections are:
Guy killed someone in a ritual that gives him access to dark magic, has done so many other crimes he can't be anything but guilty to the point it would give him at least a life sentence, and he can control minds...
Yeah, make him one of the potential love interests and promise to
travel the world
with the third prince's fiancée, and then be working under the first prince
! who will stop at nothing to make sure his brothers are happy
. Because that makes sense, right? Right?
I'm sorry, but in any realistic scenario, that's a death sentence. Either because the first prince is out of character if the criminal isn't executed, the third prince is out of character if the criminal isn't executed, or because the author is insane and thinks that any professional espionage force would bring the person who almost
raped
the main character/third prince's fiancée into contact with the main character/third prince's fiancée.
I'm sorry, but the author's morals are messed up. Worse yet, I get the same feeling of Ouran Host Club, where the main male lead is the butt of every "but we can't let you be with her" moment... even though he's literally the one who has the most business being with her.
I get the feeling part of the reason the entire cast is naive only when it comes to sex is because the author just doesn't know better... and wow I did not intend for that to become a "virgin" insult (I am one), it's just most of the core cast treat sex like they're little kids.
They don't feel human in any way (insert Miyazaki was right statement: manga and anime are created by people who dislike normal social contact and don't know what real people are like).
The series is funny, and for that alone it's worth checking out, but it makes the mistake of asking its audience to take it seriously when the very elements that make the comedy work also undermine the ability to see this as a proper drama.
In fact, most of the comments I've read are more interested in the memes of the airhead accidentally creating a reverse harem, not in the actual story.
