My way of writing

"…" - Used for conversations and in case I close the quotes and continue writing in the same paragraph, I will put [ - ], to separate the conversations.

'...' - Used for thoughts.

{...} - Used by Entities.

<...> - Mental conversations.

[...] - Used for when I want to leave some comments or for me to demarcate some Techniques, Treasures and so on.

If it appears [*] before any speech, it means it is in another language, one that the protagonist does not understand.
