I never knew this was a thing people believed about CPUs! Back when HDDs were standard I definitely thought that filling up the drive made it slower though.

Mephistos and Fausts are the best semi-intangible cloak enemy the series has ever had. Sin scissors in 1 and 5 are gimmicky and very easily beaten (though 1 handles this better) and the Fallen in 3 just suck.
