@apothem I wonder about that too.. I'd thought it was response to Saiki's thought that occult things like that don't exist. But it wasn't really question ?
My thought on the "No" is that Saiki said "this girl is moving it on her own" as in spelling T-E-R-U-H-A, but it actually is the spirit's doing until he interrupt it. Hmm maybe something else idk im just so biased with kokomi lol
