Lancer Cúchulainn, a famous hero of the Celtic mythology of the Ulster region of Northern Ireland, is also known as the 'Child of Light'.

In addition to possessing superb marksmanship, Cú Chulainn is even more decisive in combat.

In terms of appearance, Cú Chulainn is also handsome enough, with blue hair tied together and behind his head, and the Gáe Bolg (Piercing Deaththorn Spear) in his hand is emitting a faint red light.

The Gáe Bolg is a slender, red spear that delivers irresistible damage once the Noble Phantasm's true name is unleashed.

This move, which has a reversal of cause and effect, is a great threat to Mouton.

"Elijah."

"I see, brother!"

Illya flew up, not giving Cú Chulainn any chance to speak, holding the ruby sapphire wand, and her body began to exude an astonishingly large amount of magic.

Illya, a heroic spirit, has a full B-level magic power, and in the face of Lancer, who only has C-level magic power, she can naturally bring out a huge amount of lethality.

Cu Chulalin's eyes suddenly constricted, even he didn't expect the enemy to be so decisive, he would directly use the ultimate move when he came up, and Caster could fly, which was completely disadvantageous for Cú Chulainn.

"There's only one way to hit her...... Throwing...... Even if she is on a mission, she will be hit by the attack unleashed by this Caster. ”

"Quintet Fire!"

With Illya's shout, the surrounding space shook violently, the howling wind blew, and the light cannon formed by the huge magic power fell with a bang, and Mouton, who was standing in the distance, looked at the suddenly disappeared Cuchulainn, and a faint smile appeared on his face.

Looking at the huge pit that was blasted out by Illya, the corners of Mouton's mouth twitched, and he never imagined that the master of Lancer would actually use the Command Charm to recall.

Illya's figure slowly landed in front of Mouton, looking at the pit that was still smoking in the distance, Illya said with some embarrassment: "Brother, did I put the attack a little too big......

"Almost, if his master doesn't use the Command Spell, it shouldn't be possible to carry it with Lancer's magical powers."

"So what are we doing now?"

"Do you still have the strength?"

"What...... What the? Illya was stunned for a second, and Mouton grabbed Illya, and the figure quickly retreated towards the rear.

"Boom!!"

At the moment when the two of them left, the huge arrows that fell from the sky caused an astonishing attack force, looking at the huge crater, Mouton's black eyes looked into the distance, and the corners of his mouth twitched.

This red A should have memories similar to his own...... They would attack themselves in this way.

It's like you're beating yourself, and it's an indescribably strange feeling.

"Brother, what the hell was going on just now?"

"Archer did it, but there's no way to hurt us."

……

Calmly putting down the arrow in his hand, Red Archer's eyes looked at Rin Tosaka, who was standing behind, who was his current master.

"Dodge."

"Can you get out of the way?"

"It's a little strange if he can't dodge this kind of small means......

"Okay, that's all for today, well, if you can, I'd like to meet Shirou...... He really looks a little similar to his previous brother, and you are the same......"

Red Archer paused his arm, coughed lightly, and said solemnly: "They are our enemies now, so don't think like that." ”

"So we just want to go, let's go, it's time to leave, or our whereabouts will be exposed."

"It's already been exposed."

Rin Tosaka's face turned red, and he glared at Archer and said, "I mean that I can't expose it to other masters. ”

……

There is a gorgeous castle deep in the mountains of Fuyuki City, which was damaged a lot of times ago due to some battles, but after a few years, it was completely restored and redecorated.

The castle is called Einzberen, and it is the temporary residence of the Einzberen family masters who participated in the Holy Grail War.

The maiden's name was Illyasfil von Einzberen, one of the lords of the Fifth Holy Grail War.

Receiving the latest information, Illyasfil's expression became extremely strange, through the photo in his hand, Illyasfil saw a girl who looked exactly like herself, of course, there was only a difference, that is, height and age that looked different......

"The people who followed Shirou...... Who the hell is she...... Was it Caster summoned by Shirou, and why did he look exactly like me? ”

Illyasfil's heart was full of puzzlement, and after a moment of silence, Illyasfil stood up from her seat, and she was ready to meet her father's adopted son, whom she had summoned...... The strongest Berserker.

……

Mouton and Illya have been eating on the street, after the battle just now, both of them need to replenish their strength, fortunately, Mouton's magic power is extremely abundant, even Illya, who has just released the Noble Phantasm, has fully recovered, it can be said that as long as the spell in his hand, Mouton can even let Illya carry out the Treasure Triple Shot.

It's a bit irrational to just do that, so Mouton naturally saves if he can.

"Brother, try this."

"Well, it tastes good."

"My brother usually cooks good food, and if you compare it with the outside, the food made by my brother is really more delicious."

"You still don't get tired of eating."

"Of course I can't get tired of eating, Serra's mouths are all tricky."

"Haha."

Mouton couldn't help but laugh, and was about to reply, when he saw the girl in the purple coat in the distance, Mouton's expression suddenly became weird.

"Brother...... What happened to you? Illya looked in the direction of Mouton's gaze, and couldn't help but widen her eyes when she saw the girl in the distance who was watching the two of them.

"Brother...... Brother!!! So, what's going on there?! Why am I standing over there?! ”

"Calm down, remember what I told you, Illya."

"You mean...... The girl standing in the distance is Illya of this world? ”

"That's right." Mouton was also a little surprised, he didn't expect Illyasfil to come to him on purpose, and to appear on such a crowded street.

Illya Field, who was wearing a purple coat, slowly walked up to the two of them, and after staring at the two of them for a moment, a faint smile appeared on his face: "Shirou, this should be the first time we have met, right?" ”

The Illya of this world, according to the established situation, should be Mouton's...... Sister.
