Team Anna!
With Ariel hacking, Isaac didn't stay too close to the red head, between her sword and his claws something could go amiss and that wasn't ideal. Leaving Anna's protection to Loki and Elsa wasn't exactly a hardship, he was aware that Elsa was very protective of Anna, and Loki and Anna seemed very close, even if there were the occasional threats towards genitals. But there was a steady prickling in the back of his head that he recognised as the need to protect pack.
He'd felt it before, wasn't surprised that he felt it again now, even if no one here was werewolf like him. As two demons approached, both somewhat resembling lizard like things but bigger, Isaac felt his claws grow longer as he gave in to the more animal of urges.
The lizard things had fairly thick flesh, long limbs and strength to match his own, Isaac barely really paid attention to finesse or skill though, slashing at throats and baring his own fangs in a rumbling growl. Slick blood coated one hand as the first demon went down with a shriek and flail at it's throat, the other landing a swipe at Isaac's head to stun the wolf before he recovered enough to grab it, swinging it around and going in for another slash, claws digging into its chest where he assumed the heart would be.
He was slightly further away from Ariel and the group than he'd have liked to be, but until this thing went down he wasn't letting go of it to move closer.
