[ You know you have at least one person who wouldn't mind fighting a demon. Though definitely not going out of his way to summon it first, that would be dumb. Like very dumb. Like what most of Caster's do actually, but you know, he's not one of those crazy nerds. ]

[ But you know if the demon is already summoned and plotting something evil, he's down to Kick Ass of That Thing ]
