What about we use this so called "logic" thing.
1. Anime aesthetic: so anything and everything can aesthetic, even if there's pictures. Why even bother with going on from the OP? Just lock the thread after "everything is aesthetic."
2. Misa is multilinguistic: Andif she is, why would she choose English? If she knew English, Japanese, French, Spanish, Bohemian or Klingon... you'd expect an intelligent high level military personell to choose any language arbitrarily?
3 It's a movie: again... choosing the language, it's after Space War One, Most of the planet's civilization was wiped out and then repopulated. The Entertainment business once again becomes lucrative enough to make a movie about the one major catastrophic event that every person can still relate to... English was chosen due to a coin toss?
Maybe you should look up the word "logic" before you use it as an argument.
