Blurb revised (tentative); the core premise is unchanged.
They have a child whom they dearly cherish. White-haired and blue-eyed, with breathtaking beauty, the child always bears an overwhelming burden on their shoulders, and sorcerers call them the strongest sorcerer of the modern era.
But their child always dies an untimely death.
The first time, they die because of a moment's carelessness during a decisive battle with an enemy. The second time, they are sealed inside the Prison Realm and swallowed by an endless flood of time. The third time, they die as a child from a prolonged high fever, their Six Eyes draining them...
Again and again, they reverse time countless times, hoping only that their most beloved child can break free of the threads of fate leading to death.
But each time, their most beloved child dies in a more careless and absurd way than before. Worse still, the child's untimely deaths throw the entire worldline into chaos.
If death cannot be avoided, then I can accept taking your soul back from the Lord of the Underworld after you die.
That was the thought of World Consciousness.
They searched across countless other worlds, both similar and different, and at last found a sword.
A sword that could save thousands upon thousands of people with a single light swing.
Better still, the sword's wielder was also a child dearly cherished by their world.
World Consciousness: "Dear colleague, I have a splendid idea..."
Theme: Cut through every obstacle and fear no hardship.
