Also, they might be looking for a PDF to read, which could be an issue since distributing such content without permission might be against copyright. I should advise them to check official sources or platforms that host legal copies. If it's a fan-created work, directing them to forums or fan communities where such content is shared legally would be better.

They might be looking for a specific fanfic that they heard of before, so providing tips on how to search for it would be helpful. Maybe using keywords like "Azula fanfiction en español" or checking AO3 (Archive of Our Own) if the content is there. But emphasize the legal aspects.

In any case, the safest approach is to inform them that there's no official book titled "Azula Seven Rue" but suggest they look into fan-made works. Also, remind them to respect copyright when accessing such materials. Offer alternative options like legal platforms for fanfiction, like Fanfiction.net or Wattpad, where they can find Spanish fanfictions if available. Additionally, if they're interested in Azula, maybe recommend some known Azula-centric stories or books that are officially available in Spanish.
