Welcome to Gensokyo, where common sense does not exist (but general relativity does). Although general relativity does not make sense at first, though.
Oh!Sakuya declined though, right?You know first-hand...The "ability to manipulate distance" is a variation of time-based abilities.Wait, wait a minute.Patchouli must have called for her help only as a reference to time magic.Doesn't that mean she made the spell based on Komachi's "ability to manipulate distance"?...how Sakuya utilized her "ability to manipulate time" to elongate the Scarlet Devil Mansion's hallways, correct?No...
