In the triangle hearts universe.
Nanoha's dad is dead.
Her sister and brother aren't related and have sex.
Her family is a bunch of assassins with the cafe being a front.
There is no Fate. Chrono is the love interest.
Lindy is a fairy.
Nanoha has a foxgirl familiar in miko garb.
Lyrical Nanoha is an alternate universe that has managed to abandon the trappings of the original H-game and warrant its own original manga and storyline.
However trolls and people who can't fap without seeing another man's dick in the frame will always pick Chrono or Elio or some other generic self-insertion avatar over Fate x Nanoha.
