Luci was named after Lucifer, also known as Satan, who was the second of the four Archangels created by God.
According to Gabriel, Lucifer was God's favorite celestial, but when God asked for all angels to bow down to humanity,
Lucifer refused both out of jealousy and wounded pride over being commanded
to bow to what he saw as a broken, flawed, and murderous species and no longer feeling he was God's favorite creation.
He waged a war against God but was eventually cast out of Heaven, and banished to Hell by Michael, where he is now locked away in his cage.

Luci is nothing like the archangel he was named after. He is a polite and calm tokota, but dislikes loud noises.
He is often seen resting on warm rocks in the sun and enjoying the warmth.
When he was young, other pups always told him that he is way to old to play with them because of his fur.
This was the reason he often got into fights. But now he doesn't mind it when pups tell him that he looks old.
