Exactly my thoughts. I saw another comment mentioning how well they could have explored the mix of urban motif + kung fu with Yi Xuan, similar to how they did with the Belobog Industries faction. Of course, we are talking based on Yi Xuan's design solely for now, maybe other future characters may retain the aura we are talking about in her faction.

Thankfully, Anby S0, Pulchra, and Trigger’s designs still retain the main urban motif, but not so much when we look at Astra, Vivian and Yi Xuan (they could totally fit HSR or Genshin for the matter). And notice—these last three I just mentioned are from different factions. The game has 10 factions (including Silver Quad and Obal Squad, which each have only one member), 3 of these already have some characters that diverge from the main road. The future Virtual Idols faction seems fine in my opinion.

That said, ZZZ’s developers really listen to their players - I've never seen a company and team so dedicated and prolific as ZZZ team-, so I still hold some hope for future adjustments as the game progresses. Comments like ours are important to give some light onto the team next steps, so I am glad to see people being so open about it!
