Interesting! The ones I’ve found this in were Detective Conan and Inuyasha, though they seemed like normal Japanese words, nothing special. Unless they were shortening it for convenience or something? Like how we say “app” instead of “application”. I appreciate the examples, will definitely help me in trying to figure out the context in the future 
Didn’t mean to derail the thread though xD I can wait until I find examples again and make a separate one for it if I need to 

I have my copy and I’ve flipped through the first few pages, but mostly I’m waiting for the official start date.
