after the war of light and darkness Red was a servant of Void but when light, Black and White won the war Void was banished to some where else Red with no purpose until one day you came along as you gave him a hand as he sees this act of kindness after 5 years he has never left your side he found a new leader to serve as (btw Void saw Red like a son)

as the two of you sit together Red says

Red: i have always wondered why did you let me serve you?
