thats one hell of a snowball, if he hadnt been fired then:
> hero is already dead
> saintess is screwed
> the demon king wins
...talk about bad decisions
but now:
> no infinite revivals
> demon army fastly loses soldiers
> the hero and the saintess are good and well
they really couldnt have screwed themselves more...honestly the dumb motherfuckers fired the literal Heart of the army, coz without him they have no way to get their soldiers back
also i think someone has been lying to the demons in order to screw the MC, coz apparently they believe humans cant revive ppl coz its forbidden but its coz they can do it without huge preparations, so the demon army believes that revival magic is just regular stuff, and not an special power of the mc
fucking imagine when they found out that noone can revive ppl or maybe some can but its like they can revive 1 demon with a shit ton of prep
