I have decided to use specific OCs for specific franchises.
Clark will be used in Fire Emblem, Dr Who, and Initial D, and Sword Eater
Levi will be used in Pokemon, Hetalia, Sword Art Online, and Vocaloid
Sakura will be used in Hetalia, Keroro Gunso, and Vocaloid
Sasha will be used in ? Do you know where would be a good series for her?
However, I may sometimes breach this system and make a story of Clark in Hetalia or Levi in Keroro Gunso.
Thanks for reading!
