Yaya and I
Yaya is a person with turquoise hair, a pink clip at the top of their head, and turquoise eyes. In the I~ya I~ya I~ya PV, Yaya wears a pink hat on their head, white-pink plain t-shirts with weed logo on it, light blue shorts and a pair of pink sneakers. There is also a bandage patched on their left leg. Meanwhile in Let's drop dead, Yaya sports out a pink tracksuit with blue collar and a pair of white sport shoes.
Same as I, Yaya is described as a lazy person, hopeless and wasting their whole time.
