Prologue — The Measure of Kings
In the Heian era, when sorcery reached its peak and curses reigned like gods, an S grade spirit was born from the ugliest of human feelings.Not hatred,not envy and not rage but inferiority.The crushing weight of feeling small.
This cursed spirit had no name but a purpose to make humanity feel inferior but how would it do that when it was inferior to other curses.It tried to rule over other curses but barely survived the fight .So it did what humanity did when feeling inferior ,hide away from mockery by other curses and sorcerers
Unfortunately it came upon a being later known as the King of Curses .Tired of being inferior it recklessly challenged Sukuna.Tge spirit lost miserably however Sukuna spared its life, not out of mercy — but to humiliate it."Crawl, little insect. That is all you're worth."And so the spirit learned despair.It questioned it's existence and it's purpose
It wallowed in weakness, believing itself forever beneath all things. Until one day, when it chanced upon two sorcerers fighting , it witnessed something miraculous.One of the sorcerer on the verge of loss but through sheer will broke through by performing reverse Cursed Technique.
A hand that healed instead of harmed. A light born from darkness.
If negative could create positive… then why could inferiority not become supremacy?Why could the smallest not rule the greatest?.Like a dam cursed energy rushed throughout it's body as divine words where branded in its soul.The cursed spirit awakened its true nature:Divine Cursed Technique — Magnitude Rule.
It could command scale itself,if other things make you feel inferior then reduce their size so U become superior to them.
From that moment, the nameless curse gave it's self the name Ōsamaru and began a journey.
To battle the finest sorcerers of the golden age.
To challenge Sukuna again, not as an insect, but as an equal.To carve a throne higher than any king.
And though the ages buried him in darkness, sealed away by Kenjaku in a void prison… the day would come when the seal would break.
When he would rise again.
Not as a king.
Not as a god.
But as the measure of all creation.
The one who sits upon the throne of fear itself.
Ōsamaru — the God of Scale.
