Jujutsu Kaisen: I Can Travel Back in Time - Chapter 12 - 6: The Shinigami and the Sorcerer

Within the dream of the dreamer, the one who was dreamed of awoke.

… Borges

“I exist in the sunlight, the wind, between the heavens and the earth, and also in dreams.”

One night, Yu Hao, a college student who was at his wits’ end had an unexpected encounter with a mysterious visitor – “General” – who had dream travelled. He led Yu Hao in solving the countless riddles that abounded in the realm of the conscious, and lit up the fire beacons on the meandering Great Wall.

Thereafter, the darkness retreated, the sun rose, and when the long night was thoroughly lit up, the him who existed in reality was reborn.

The black dragon that roared, the lighthouse and demonic eye on the coastline, the rain forest before Chichén Itzá, the fierce beasts that wreaked havoc in the Colosseum…the bizarre projection of reality in one’s consciousness reflected the hidden place that the sunlight in reality couldn’t touch – the innumerable sins of the human heart.

The journey of seizing dreams continues, and one can only hope that the sun will continue illuminating the human heart.

…

Fire beacons on the Great Wall were lit up to signal a border invasion.

I have given up power that can make the strongest of men tremble. I bore scars very few can imagine; loved women, very few had the gall to talk; and tread paths with chaosfiends.

Gale was summoned into a mysterious world of magic and monsters for no particular reason. Thrown into squabbles of beings vastly higher than him, Gale strived to make a place for himself in the vain dream of immortality and a better world.

That was six years ago.

Beaten and battered from years of brutal war, Gale finally had enough and resolved to start over a new peaceful life in a totally unremarkable town with his trustworthy companion, Vale. Give up the weapon of slaughter and take up a hoe? That seemed like a fine deal to him.

Unfortunately, the valley wasn't as unremarkable as he thought it to be. Dictatorial governing bodies, suspicious practitioners, an exceedingly unwelcoming guest, and a secret that would change the entire world, all impeded his peaceful life. Gale will need all his mental stability to keep his temper in check, lest he brutalises his way out of trouble. Again.
