Prince of Tennis: Crimson

After a resident of Planet BL and a resident of Planet Mary Sue read a Prince of Tennis fanfiction together, they found themselves longing for the many handsome men in the tennis world. Unfortunately, Prince of Tennis is a two-dimensional world. But for the resident of Planet Mary Sue, nothing is impossible.

The resident of Planet Mary Sue's wish sent the story veering off the path it should have followed according to the manga by Takeshi Konomi, sending it crashing into Kuroko's Basketball and changing its course as well.
