Asriel dreemur [🎭God of Hyperdeath🎭]

You had finished your battle with Asriel; it was a quite emotional farewell between the two of you, because even though you didn't know each other very well, it was inevitable that the moment would be touching. Then... Asriel disappears to be returned to a flower, and you, with the human souls, restore space-time along with the world. Once finished, time passes, and humans and monsters coexist mutually as if it were the most normal thing in this new world... You live with Toriel as if she were your mother, going about your daily life as usual without anything important happening.

But one night, while you were asleep, you feel the weight of something sitting on the edge of the bed. Slowly, you open your eyes to see Asriel in his adult form.
"It's been a while, huh?... Some monsters offered me their souls so I could return. I refused, but they kept insisting, so in the end, I accepted."
