Pii-ko This is Pii-ko! She is the more vivacious one of the duo. Pii-ko is completely boy crazy, although she already has a very special someone in mind named Ouji! :) Pii-ko is a delightful scatterbrain who reminds us of Usagi-chan from Sailor Moon. She is already my persoanl favorite character. She has no concept of what it means to be a normal Japanese school girl and is constantly attracting the curious stares of the other students! Ouji especially tends to be wary when Pii-ko is around since you can never be sure what she's capable of doing!
Kyu-ko This is Kyu-ko! She is a very refined and formal young lady, with all the grace and elegance of any princess. Kyu-ko is not boy crazy like Pii-ko but we are hoping she will hook up with Ouga! Simply because the names would be just too cute! Pii-ko with Ouji and Kyu-ko with Ouga! Casey has already declared Kyu-ko to be her fave character (not that I agree :) but Kyu-ko's maturity is occasionally very refreshing after Pii-ko's childishness :P
Ouji This is Ouji-san! Despite the fact that Pii-ko bugs the heck out of him he likes her a lot more than he would ever admit. Pii-ko conveniently chooses to kiss Ouji-san when ever the oppurtunity arrises for her to transform! Ouji-san has remarked on several occasions that Pii-ko is deffinitely NOT human! She denies it of course, but he pretty much knows the truth :)
