Chisa Peach Parfait
If there's anything I learned from playing a lot of gacha games in the past few years, it's that good support characters are actually more valuable than heavy hitting DPS units and Chisa is most likely one of the valuable characters you can have in your roster. As a support she's not tied to any specific elemental teams and she can support just about any team combinations you can create so far, some people say she's literally futureproof.
I do like using her in the game but somehow I personally feel I find it very difficult to draw her well. Maybe it just boils down to personal preference but I think I shine when I'm drawing gyaru like Lynae. That said, I absolutely love the swimsuit Kurogames gave these two characters. I can only hope they'll make more skin for all characters in the future.
