Rainbow:
Saffron, hands down. Her skill attack, crossbow, and smoking pipe combine all into badass adorable girl. Top priority of the list.
Tree of a thousand stars I guess I always have a soft spot for tomboy girl that has a streak of girlish side. Her blue bird is definitely a plus.
Dusty Miller Her flying glow swords are cool. Also love her talking style.
Gold:
Hop Her drunken sprite is just gawd hilarious.
Panama Queen Delicious tan-skin. Hands down.
Aloe Her passive skill is top-class. Has bloomed form too. Also I love all of the artist work I guess?
Plum (Yukata) Funny I love this version more than her original one.
Tiger Lily Love her design and lighting based attack.
Devil in the Bush One in the high priority for gold. Too bad my luck is always just abysmal when come to priority gacha.
