[Synopsis]
Uchiha Madara, the legendary demon of the ninja world, died and came back to life several times, but in the end, he still died after the Fourth Great Ninja War.
Then he came back to life again.
This time, however, he had been brought back to another world through "Edo Tensei" and become a "Heroic Spirit." He had also gained a young Master named Kiritsugu Emiya, later known as the Magus Killer.
Among magi who sought the Root, young Kiritsugu was an oddity. But he had a great dream, no less ambitious than that of this great final boss: world peace.
Kiritsugu was born in a peaceful era, yet lost his parents, his lover, and his teacher while still young. In the end, he was left with nothing. After personally blowing up the plane carrying his teacher and a vampire with a rocket launcher, he wandered into a Heroic Spirit summoning circle while exploring ancient ruins and summoned Madara, a top-tier Assassin, through compatibility alone.
Uchiha Madara silently absorbed the common knowledge of this world, then looked down at his body, which had inexplicably become female, and flew into a rage. So why did I become a woman after turning into a Heroic Spirit?
(Mushroom: Just standard procedure. Don't ask.)
*
With the power of the Six Paths and a Heroic Spirit's body, traveling through time and space was no longer just a fantasy for Uchiha Madara.
Still, given the need for magical energy in the present world, this creature called a Master was, for the moment, somewhat useful.
So offer up your magical energy. In exchange, I, Uchiha Madara, will become your Servant and help you achieve your dream.
Feel honored, kid.

As the saying goes, Servants are forged in iron, but Masters come and go.
Here is the list of Masters for the battlefield rose:
1. The Magus Killer.
2. The Jujutsu Sorcerer Killer.
3. A former killer about to become a writer.
4. A wandering half-demon cub.
5. A future two-star relic hunter.
[Note]: Uchiha Madara is gender-swapped. A beloved-by-all story. The pairing has not been decided, but it leans toward Hashirama/Madara or Madara/Madara.
Theme: A person's life is a journey of self-redemption.
