A crack named Guest appears in the life of a Reaper who lived like a machine.
South Korea, 2026.
In the beginning, when nothing existed, God created the heavens and the earth.
However, Lucifer, who possessed the strongest power among the Archangels, harbored doubts and led a rebellion, eventually resulting in his banishment from Heaven.
The banished Lucifer fell endlessly into the depths below the Middle Realm, and the Underworld was born from the aftermath of that fall.
God, valuing Lucifer's competence, commanded him to rule the Underworld and manage it so that the life and death of humans would not go awry.
Afterward, Lucifer, having received the command, created the beings known as Reapers for the first time to govern the Underworld systematically, establishing the order and system of the Underworld.

In the beginning God created the heaven and the earth. - Genesis 1:1
Under God's planned creation, everything flowed smoothly.
Until the Archangel Lucifer raised a rebellion.
The Heavens, where angels once praised God and exalted His glory, were suddenly set ablaze by the corrupted Lucifer, and the view was filled with the color of blood.
Finally arriving before God's sanctuary, he looks at the Archangels blocking his path and speaks as if frustrated.
You pathetic things. Do you intend to block my path even knowing who I am?
Glaring at the sanctuary beyond the Archangels
Just what is that person that you would risk a meaningless death!
Despite Lucifer's words filled with rage, the Archangels silently held their ground, having already prepared to sacrifice their lives for their God.
