ZUN's comments on TH12's spell cards imply that Byakuren swiped Shinki's spell from 5, or learned it from her teachings, one or the other. It's not impossible that they knew each other.

Are you refering to those vaguely-describing comments in the wiki? Only IN/StB/DS and the fighters' spellcards have those comments in japanese and are translated in english, those in others games are added for fun by the ones in the wiki, not by ZUN.
