EXP Is Golden: Volume 1 - Great first volume. It's at the core a kingdom-building and game character progression story. MC more or less stumbles into the role of the final boss but decides to embrace it completely. No altruistic saints cosplaying as "Evil(TM)" is to be found here.
Babel, Vol. 2 - I really can't follow MC here. She takes actions that are completely unfathomable. For example, trying to kill herself to win an argument. I wish I could make this up. It's also made up of a lot of conflicts that could completely be averted if characters wouldn't treat information as if it were a secret. A simple "Oh hey Mr. Employer, I've overheard two suspicious people in the courtyard and it seems they want to use some sort of item on you. They sounded as if they didn't like you but they really were a fan of someone called "insert name here". I don't know more but I thought you might want to know...". I wonder if this is its own thing or if this belongs to the "oblivious MC" trope. I mean looking at how stupidly oblivious MC is in general I feel it would fit at least. That all being said, there are some genuinely interesting concepts in this series. If those concepts were handled better (and MC were different) it could really be one of the stand-out titles—so much wasted potential.
