During [Judgement Day] which occurred every [Millenia]. History began to be altered by the betrayal of Tiamat who became a [Fallen Angel], that succeeded in defeating Cylica and obtaining her power. While the world was still in chaos, Cylica parted her soul to [Earth] in an attempt to escape Tiamat's grasp.
Michael August is a name given towards him by Cylica. A [Seraphim] that self proclaimed herself as the strongest Angel in heaven. Due to an unreasonable request in a life and death situation, Michael had became a [Sage], a higher form of a [Hero] for whatever that is. His body and life had also been altered, as a result he also had to go along and defeat the [Fallen Angel]s. Other than his luck, can someone who has no special abilities, bad social skills, and a coward, being entitled one of the weakest common soul. actually work out with the prideful, strongest spirit to save the [Fallen Angel]s and restore order to the world?
Michael as a Sage can obtain the abilities of the souls he defeats granting him their power. Other than that, his body became gender fluid and can easily alter itself as either gender which he himself can't control. Although, in one way or another it might actually be useful.
