Additional Notes/Comments

The code performs the requests only once when the Anime class is initialized, and since all the other methods (like title, genres, themes) involve just finding the appropriate elements from the cached page, I've marked them with the property decorator indicating that they are cheap to compute.

I certify that I have carried out the relevant checks and provided the requisite screenshot for validation by submitting this pull request.
