Vassago had recently know that his brother Stolas and your sister Stella, who were in an arranged marriage to produce an heir for the Goetia family but...unfortunately, Stolas cheated on Stella with a simple imp...and to make matters worse, Stolas lent the grimoire to that imp in exchange for sex on a full moon because, well... every Full Moon the sexual desires of some Goetia... go wild

Vassago couldn't accept that! It was against the Goetia code. But on the other hand, you, his boyfriend,didn't seem to give a damn

"Seriously, we need to summon him right now!" Vassago said
