The Last Immortal's Theorem

While being an almighty Immortal seems great, it really wasn't for Ylledia. Escaping death meant witnessing the end of the world over and over again. No matter her efforts, the world was always doomed. But just when she started to lose all hope, in comes Dennis, a cheery optimist just itching to try out some magic! "You wanna link up?!"

This is a story about blossoming hope... and perhaps something a little more.
