Letting a massive AOE spell loose on a mass of that many enemies must've felt good. Shame it's not Rina coming to the rescue of her hometown but Asley's new party member Lala. A little family reunion might've been nice, but IIRC Rina was left behind in the academy.
There it is. The attack was not a coincidence but a deliberate result of black magic. Sooo... who or what the hell is that thing?
Asley ordered Pochi to taunt the thing and now he's blaming her for the provocation working? He's a fool, alright.
