The End of the World: My Sequence Is the Funeral Angel

A college student who is about to graduate and works part-time as a delivery boy. On the day of the apocalypse, he was delivering food to a high-end office building and was trapped. In a desperate situation, he did not awaken the common elements and powers, but accidentally fused the most bizarre "funeral angel sequence" that was regarded as ominous by others. This sequence can acquire their memories, abilities, and energy by devouring powerful life forms (including zombies, mutant beasts, and even... Humans) to achieve infinite evolution.
