I feel like the goddesses don't wear panties as a power move. Why would they be stricken to such mortal things as needing to wear underwear? They wouldn't wear any clothes at all if we're going to be real. So 2hus like Kanako are definitely walking around without panties. I mean think about it this way...her official Zun art shows her sitting with her legs open. That girl is letting her vagina remain unbothered by fabric. No pantsu on that godly cooter.
