Honestly, I don't like a lot of character's voices. I played on mute for so long that I've built up what they sound like in my head, and then the VAs don't sound anything like it. Xiao particularly.
Other than that... 95% of the women in this game are low-effort waifu bait. Like really, I'd pull for some of them if they bothered making them interesting. I was planning to pull for Kokomi... well, the Kokomi we thought she was before we met her.
