FATE/STAY NIGHT

[FUYUKI CITY]
At the forest in the outskirts of Fuyuki City stands a beautiful castle covered in beautiful white snow.

The residents of this castle hurriedly came out the castle as they could feel that something or someone is coming.

SELLA

LEYSRITT

Illya: BERSERKER!
A figure came out from the castle.

And stands beside Illya and waits for his master orders.

"CRACK""CRACK"
loud cracking sounds boomed throughout the entire forest, Illya and her two maids[Sella and Leysritt] looked up at the sky and saw cracks starts to appear on the sky as if in any moment the sky will broke down on them ....a portal opened up in the sky which shocked Illya and her two maid,A devilishly handsome young man steps out of it and studied his surroundings, Illya gasped and covered her mouth with her small hands when she saw the familiar figure..
[IRIS]

Tears rolled down from her cheek.

Illya: M-MOTHER!
The two figures who is floating on the sky looked down at Illya, Sella, Leysritt and Berserker.

Iris: Mother?
She said in confusion and looked at
Y/n.

Y/n: hmm...you two look very much alike.
He stated, Iris nods her head on Y/n words.

Y/n: hmm...t-this..
He stated in shock and looked at Iris, he then touched her forehead with his finger and showed her every single memories of Illya to Iris and her mother Irisviel who looked similar to Iris.

Iris: this...
She was shocked when she saw all those memories of how little Illya was trained by Einzberns so she could be able to control Berserker but soon her shock changed into anger....

Y/n: Iris.. it's okay..
He said with a smile and calmed her down, he then descend down on the ground with Iris, Illya rushes towards Iris and hugged her close to her.

Ilya: M-Mother!
A beautiful smile appears on Iris face, she looked down at Illya lovingly and put her hand on Illya hair and stroked it gently.

Iris: Illya...

[TIMESKIP: TWO MONTHS LATER]

~EINZBERN CASTLE~

It's been two months Y/n and Iris came to this world and adopted Illya as their new daughter, Illya eyes shone with happiness when she saw Eri and how cute she is....as for Sella and Leysritt Y/n made some changes in both them...and extracted the dress of heaven from Leysritt which could control the Great Grail...as for the head of the Einzbern family well let's just say a month ago he got devoured by a certain dancing clown. Illya was sad when she came to know about her father "Kiritsugu" who tried to save her from her cursed fate, but thanks to the barrier around Einzbern castle he is prevented from succeeding.

[PRESENT]

Y/n: so it finally begun huh!
He stated as he could feel the presences of other three servants in Fuyuki city and looked at Illya who's combing Eri' hair.

Y/n: Illya..will you help me to summon a servant for myself.
He asked her, if he wanted he could summon every servants from the thrones of heroes but he decides not to since Gaia and Alaya will be suspicious off his presence and will try their best to eliminate him...well if they try to do anything funny...kekeke.

Illya: "smiles" un...
She nodded her head with a cute smile on her face.

[TIMESKIP: SUMMONING]

Y/n: What t-the...these chant is too long..
He said as he read the summoning chant which was given by Illya. Illya chuckles on seeing Y/n antics.

Y/n: well...whatever...
He said and throws the paper in the dustbin which confused Illya, before she could say anything Y/n snapped his fingers. A magical circle appears on the ground which shocked Illya.

Y/n: ACTIVATE!
The circle starts to glowed brightly soon a abbreviations of a figure starts appears inside the circle. A tall voluptuous woman appears inside the circle. She wears a hooded bluish- purple robe which covers her face.

[CASTER: MEDEA]

Caster: I ask you...are you my master!
She asked Y/n, Y/n nods his head. Caster was shocked when she saw Y/n, she couldn't believe her eyes that a man could be this handsome but what shocked her is the overbearing aura Y/n is releasing for a moment she thought she is standing infront of a being who is as strong as those filthy God's and Goddess that ruined her life...she tried to sense Y/n power but what greeted her is an dark abyss that has no end.

Y/n: nice to meet you Medea.
He said with a smile and offers a handshake, Medea eyes widened in shock when she heard her real name.

Medea: who are you?
She asked Y/n with hostility in her eyes.

Y/n: "chuckles" Y/n L/n!
He said with a chuckle and walked upto her before taking off the hoodie which covers her beautiful face, he then looked in her eyes warmly.

Y/n: I can feel your pain...I was once betrayed by my loved ones too..
He stated while staring at her beautiful eyes.

Y/n: Illya come...you too Medea.
He said with a smile and walked out of the summoning room with Illya leaving behind a shocked Medea who's blushing from head to toe.

ENJOY.
