Book Combo Tag (Manga Edition)

Tag questions:
1. What two authors would you like to see put their writing skills together to write a book?

2. What is your favorite author collaboration? Whether it be a short story collection or just a book that the authors worked together on.

3. If you could combine two stories and make them a book of their own, which would they be? & what would the reworked title be?

4. What two characters from different books do you ship?

5. What two worlds from different stories would you like see come together to be one epic world?

6. What duology/trilogy/series would you have liked to see be combined into one book?
