Soul Guardians

When a person dies, their soul turns into a butterfly and flies away. Holding the thoughts and consciousness of the deceased, this butterfly can last for 49 days before fading away completely.

In this world, the Death Bureau, a national agency that collects and freezes dead souls’ butterflies, lets the family of the deceased interact with the data in their relative’s butterfly through a 3D hologram. Their duty also includes making sure butterflies don’t end up in the wrong hands – without killing or getting killed!
