>>119539366Pretty much, yeah; it would take a spiritual entity of high caliber to deal with him, and from what we've seen, Remnant doesn't have that or even a similar concept.
I mean, there's Jinn, but does she fight? It's totally possible that the artifact of destruction can put him down, but who knows what it's actual function is? Alternatively; it's possible that in his jumpover to Remnant he could be treated as 'close enough to' a grimm for Ruby's silver eyes to work. He won't die to that on account of his rewind ability kicking in, but he would stay the FUCK away from her afterwards due to his cowardly nature.
>>119539386>>119539390Angra Mainyu and Salem would more likely form a 'don't mess with me, I won't mess with you' dichotomy. Salem, despite being human, is effectively unkillable and therefore not worth his time. He can't even corrupt her with his curse, so there'd be no reason for him to bug her. It is in Salem's best interest, meanwhile, to just let Angra run rampant wherever he goes.
>>119539409Angra Mainyu is a bit of a special case; in theory he could end up on Remnant as a shift in reality; the [Root] could even try booting him off of Gaea and so he ends up transplanted elsewhere. Alternatively one of the true magic's could affect his core and he could be moved through spacetime there. OR just a bog-standard 'idiot on Remnant tried to summon the devil but got Angra Mainyu instead' story. How he gets there really isn't relevant, of course. It's what happens after that we worry about.
>>119539453During H/A Angra took advantage of the fact that Shirou previously got dipped in his curses (long story) to 'occupy' his body during certain times. He also used Shirou's body to get sex because hey, use it or lose it.
>>119539460Without the Counter Force or an equivalent, Remnant simply couldn't have most servants.
