Aku- meaning evil in Japanese Yoi- meaning good in Japanese These girls are Japanese Gods?? I suppose They are supposed to represent yinyang, they both hold up the good and bad on Earth and regulate it, they are not related, and are not humans nor angels or demons, they also have the power to levitate and fly Aku: she's a spunky, loud, sly, sneaky girl, she's hard to befriend and once you do you'll grow sick of her manipulative tendencies quickly, she is power hungry and will use anyone to get to the top Yoi: she is known to be quiet, but she seems to always be lost in thought, she often puts people before herself and will attempt to help anyone, no matter how foolish, she also feels as though she has to be the "hero" in every situation, and this often gets her hurt, she is also hard to befriend as she is rather stressed and scared
