This is starting to get really boring. Not that the main plot was ever that interesting to begin with but I want more fun moments with Arata and his girls. Not this lackluster arc.
Why do I have a feeling that they're purposefully making this new girl the "perfect girl" so that later on they can do some supposedly clever twist that reveals she's even worse than Takamine, and then the readers start to like Takamine more, just because she's not as bad as the new girl. Maybe...
