This is a tale of Ancient Times, an Era before the human and nonhuman worlds were forever divided. Elizabeth Liones must reunite The 8 Deadly Sins once again to bring peace to Britannia under their Captain, Meliodas, and their Vice Captain, Rimuru Tempest

disclaimer I don't own that time I got reincarnated as a slime and undertale. Roy and his brother Peter, pretty normal Otaku kids died and reancarnated as there favorite undertale charecters.
