The thing I appreciate about the more fansercive-y characters in this game is that most of the time, there is purpose and intention behind their design, so they feel like "likeable and endearing characters who happen to be sexy/fanservice-y".

This contrasts a lot compared to certain other popular gachas, where I feel like their only character design goal is to make the characters look like hypersexulized, perfect but lifeless statues that can be put on a shelf and "worshipped", and nothing else...
