Haikyuu: The Knave of Spades

The Knave is sort of like a “wild card.” They are rare, only one per generation. What happens when Keiko Fujiwara IS that Knave? And what happens when Takeda Ittesu asks her to come to Karasuno to play for the male team and help them out? There will be some LGBT themes, not with the Haikyuu!! characters themselves, but with my own OCs.
