Shinigami - Wikipedia, the free encyclopedia

The above character from Death Note is named Ryuk
He is a Shinigami (死神^?, "death god" or "death spirit") the personification of death in Japan. It's unclear when the concept entered Japanese culture; it may have been imported from China (where there are several psychopomp deities), or possibly been imported from Europe during the Sengoku era—that period in European history featured a common motif of the Grim Reaper gathering souls.


AKA (Depending where you're from)
Azrael 
The much feared Angel of death in both Islamic and Hebrew lore, Azrael’s name means “whom God helps.”  Azrael’s primary role is to help people cross over to Heaven at the time of physical death.  He comforts people prior to their physical passing, makes sure they don’t suffer during death and helps them assimilate on the other side.  Working as a grief counselor, he surrounds grieving family members with healing energy and helps them cope and thrive, and absorbs their pain.

AKA (Working up the ladder, so to speak)
Metatron
One of the most important Angels in the Western tradition, he represents the supreme Angel of death, to whom God daily gives orders as to which souls will be taken that day. Metatron transmits these orders to his subordinates Gabriel and Sammael.  He has a special place in his heart for children, especially those who are spiritually gifted. After the Exodus, Metatron led the children of Israel through the wilderness and into safety. He continues to lead children today, both on Earth and in Heaven and helps them to adjust to Heaven after crossing over.
