Holy aura was the manifestation of a higher being's aura, it came out like how smell, or an exhale come out, but this could literally destroy a lower-level creature into atoms if it was dense enough.
But, Johan saw aether just like the developers of "The Less I Know the Better", a bunch of codes, laws, and rules, some permanent, some that could be altered.
Simply put, holy aura and aether itself were just codes, so using a spell like Defuse theoretically should cancel holy aura out.
'But… there's some risk.' Johan thought, hesitating to release the spell.
Olivia didn't have a physical body anymore, only consciousness—which is soul—and soul is made of Aether. What if Defuse removed Olivia's aether instead of the holy aura? Then the holy aura would dominate and take complete control over the physical body.
Olivia was still sealed, so there shouldn't be any other risks besides Olivia's life, right?
