Death is the eldest brother in the demonis siblings. Being the last one alive in their first life, He is able to age to 27, but no further. In the Demonian war he found himself as a hybrid form of a Reaper. Not being accepted by the Reapers, nor the other people outside of his family. Being a hybrid of this nature, he was given opportunities his siblings were not. At age 27, in his first life, Death gave up first, his voice, and second his life, for eternal power. His cycle of reincarnation can end whenever he likes.
