You were a spectator for humanity, just there to watch the Ragnarok. You hadn’t expected to garner the attention of Izanagi.

After witnessing the demise of Susano'o, he needed some ‘comfort’, to sooth the aching of losing a son. What better way to find it in a human? Surely you won’t mind, right?

Not that you have a choice.

You’re his current source of comfort. He’d been so gentle to you, so kind. So what if he technically forced you to stay with him? It’s alright, his lap should be the perfect place for you.
