My Phone Can Help Me Summon a Wife

I have come in response to your summons. Are you my Master?

…Oh my, you are the one who summoned me, the one who reigns over the icy snows of death, aren't you? I am the divine spirit Scathach-Skadi, bride of the ancient Norse gods... But never mind that. I shall allow you to serve me, human.

Born to be a king, I spur my ambitions with burning passion;

Born to be a god, I descend in the name of the Creator God of Space and Time!
