Might be a dumb question but which Spanish is used for this sentence?

[SOLVED]

I asked for a English-Spanish translation and I received this: "Tal vez... esté asustado... pero yo protegeré tu alma...  ¡Hotaru!"

That's great but the translator did not tell me if it's in a "neutral" Spanish or Castilian or another dialect. I would love to know which it is.
