The realization of the harem just ruined it for me. Not the fact that there was a harem–I can deal with that–but the way things played out. To me it felt like the author kept on shoving the fact that the girls’ relationship with the MC had become s*xual in the readers’ faces ALL THE TIME. It got to the point where I couldn’t even skip over those parts because it was mixed in with most of the normal (pre-romance) content.
After the harem was realized, the rest of the story (battles, training, even new characters) became inseparable from it. As a result, I’ve stopped reading it (mostly lost interest) ; however, other than that, highly recommended.
Rion is vicious, and I love his character for that. He isn't the "I'll avert my flags" sort of character, because he doesn't even realize that it is a game world. Moreover, the character of Rion isn't part of the game. His loyalty to Vincent is slightly odd, but at the same time the personality "Rion" doesn't seem to have the usual ambitions of conquering the world with cheat abilities. Rather, he truly supports Vincent, his lord.
