Yeahhh Accy's canon is based on like, aaaallll of Crowley's writings, so some of the Goetian/Hermetic/etc. stuff that pops up in Hereditary also apply to Toaru. Accelerator in particular has done some crazy occult stuff but relied on his precious trash demon daughter to help translate, because he is a big newbie when it comes to magic. If learned about Paimon's whole deal he'd be 👀 right back.
