Ohayouuuuuuuuuuuuuu, welcoming everypony! You are exile princess no LoYaL-tan, youngest student of Medium High! When your mean subjects on PONI YSLAND rebelled against your father the king, you were launched out of a cannon. Now you are supposed to build your strength until you can get your ysland kingdom back, but that sounds boring, so you enrolled as a student here instead! Now every day is a constant wacky struggle between your ysland culture and the school norms, as you repeatedly subvert your teachers' authority in the only example of subversion you or any of your friends are familiar with.
That little green sweetie who's flying around you is Kame-pi, your SHELLPONI. Shellponies are just one kind of PONIMON, the wild and highly marketable natives of Poni Ysland. Fortunately you brought a whole Ponimon Booster Pack with you to Medium High, so all six of you get to train Ponimon of your very own! Besides Kami-pi, you think your favorite is LoRaF-tan's PURRPONI Neko-pyon. But you all need to train your Ponimon together if you ever want to beat Skaia-sempai's elite Ponimon collection… she's just so good at everything, you can't ignore the girth of her knowledge! Gomennasai, you mean breadth~! You are still learning this language.
