In case anyone was wondering about KiKage/Sorrow from part 1, here's his bio:
Name (Past life): KiKage
Name (Current life): Sorrow
Age: Unknown
Gender: Male or Male/Neutral for Sorrow
KiKage's info: Flames' rival and close friend in their first lifetime. He fought alongside Flames against a demi-God and even merged their souls briefly to gain the upper hand, before dying to protect Flames and "...give them...freedom...". KiKage died, causing Flames to gain the last emotion he needed to attain Spirit Unity with the world: Sorrow. During the Apocalypse, KiKage was nowhere to be found...
Sorrow's info: A fusion of KiKage's soul and one of the major Sorrow Beasts. Sorrow is unlike the others and is best seen as a Neutral being who simply enjoys Sorrow and chaos. Despite his homicidal urges and unusual tendency to play cruel mind games with people, Sorrow is just another person suffering a lot of anguish within himself. He is more of a spirit, ghost or astral demon then a physical creature, usually only having solid form when 'sharing' a body...
