Thirteen years ago

In three different worlds

Three different people

Three different wishes

Three holy grails

One manipulator

A man with a chestnut spiky hair, sharp hazel eyes and in his mid-twenties stared at the shining item on his hands with dead eyes, but for some reason his eyes were overflowing with tears.

"Finally..." the man emotionlessly said.

"...my only wish is for my niece Sawada Tsunayuuki is to live. It may not be in this world —just make my niece live the life that was taken away from her…"

In another world, a woman with greenish bob cut hair held the Holy Grail near her heart as the tears flowed from her eyes. "I've been living for hundreds of years. I have accomplished all of my goals, but one. The beautiful child in my visions, Sawada Tsunayuki, I don't know if she's from this world or not, but all I want is for her to have friends and family that will love and protect her. It can be the servants or just humans."

At the same time, but in another world, again.

A teenage boy with bloody hands held the grail tightly and hate is visible to his eyes, but there are tears flowing from it.

"The life of my older sister was taken away by this war. I always thought to myself that in another world this war and servant things is just a game, but I know it is impossible because it is about the balance of the world. But... If this war can't be a game and will choose my sister—Tsuna-nee as a master, I want her to have stronger servants so that her life will not end in vain."

The grail heard their wishes and so is the manipulator.

Thirteen years ago, the original timeline

A three year old female child came out from a burning school with a few scratches and it seem people didn't notice her due to her small figure.

She looks at her surroundings with no recognition and continue walking to where what her head is telling her and then she found herself standing in front of a huge house with "Sawada" printed on the gate.

"Ah! Kaa-san! Tsunayuki is back!" A six years old blonde boy with the similar face of the female child shouted when he saw the three year old, Tsunayuuki, standing in front of their house.

The blonde child is Giotto and he is the older brother of the brunette. The brunette has been missing for two days and the parents didn't notice it because they made the maids to take care of the three year old.

Unknown to them, Tsunayuki was kidnapped by the said maid and the maid lied that she will be taking the brunette to Nana's uncle because Tsunayuki wanted to.

Also, the said uncle who is just a civilian was also kidnapped and tortured with little Tsunayuki, but the said child died. Her uncle went on rampage and awakened a sleeping power inside him and destroyed everything on sight despite his weakened physical body.

It wasn't flames but mana.

He sets the torture house into flames and left without looking back, but there were tears flowing from his eyes.

While the house is burning at its peak, the body of one Sawada Tsunayuki was engulfed by the flames, but for some reason the flames didn't burn her but protected her and healed her injured body.

A few moments later the child's eyes opened without any emotions in it and unconsciously made her way out of the burning house.

There is no memory inside her and inly her intuition is leading her to where she really belonged.

For simple explanation. The first person to wish was his uncle (who is in the future) the same uncle who went on rampage when Tsuna died. In the future world, Tsuna died the same way, but his uncle cannot accept her death so he, as a person with magical powers, managed to summon a servant and participate in looking for grail which we know he won.

The second is Yuni in other world. She was plagued with visions of Tsunayuki from different worlds and she came to became fond of the said brunette. Yuni loves her servants and she wanted Tsunayuki to experience it so she wished for it.

The last was Giotto, but in his world Tsuna is the elder sibling where the said brunette died while fighting for the war. Giotto, at the age of six when his sister died, knew about the war and participated in it for his sister and finish what Tsuna left. He was bitter that he lost her sister because if the Holy Grail and wished his wish.
