Yakko

Yakko is a wizard with a black-riding hood who's surprisingly not an Evil Doppelgänger, despite looking very similar to Chacha. She does see Chacha as her rival and instead of using magic spells, she specializes in alchemy and relies on creating magic items and potions using her wild imagination. Her rivalry is motivated by the fact that she has a huge Precocious Crush on Seravy, as turns out that she's very passionate about adult love.
