Shitty OC: Hey I just met you
Shitty OC: And this is crazy
Shitty OC: But my name is Princess Yamichan Darkshadow Higurashi Kiara Baginsky-Jones-Beilschmidt-Honda and I am the long-lost sister of Prussia and I represent Israel and Ireland and Africa and I am a inuneko and I cut myself because Russia murdered and raped me but England's magic brought me back because he loves me even though he is a rapist like Spain and I love bacon and cake and being random and I am a scene queen but I'm not a poser like those preps over there and my boobs are too big for me to move comfortably and Ukraine is jealous and I killed Hungary because she's a whore also Belarus raped me and you are my true love Doitsu-chan
Shitty OC: So fuck me maybe
