That is, the altar of the stars. The burning flame is like the connection between heaven and earth. Flickering flames shone into the void of chaos and inexplicability, baking the hard canopy that covered it.

"Oops, oops~~~ Honestly...... It's a pity~~~~~ Sakura. It was you who gave birth to "it" to this point, and although you had the intention of at least giving you the glory of the Holy Grail, you still couldn't help it. ”

"If you want to be resentful, blame yourself. It's all your fault that you can't catch the ceremony and catch Illyasfil. The evil voice sounded in the girl's body.

Click, boom. The girl's neck seems to be a bug moving. You can't see it. The girl's skin didn't crawl with bugs. -- It's not on the outside, it's on the inside.

"Well, although the body is not completely changed, but don't ask for too much. This irrational body will be taken over by the old decay. The evil voice was inexplicably excited.

"Farewell, Sakura. As an experimental subject, you are quite patient and quite pleasing to the elderly! The girl's body made a creeping sound in the veins. The extremely corrupt spirit of the inkstone of the square order, which is the body of the insect, eats the brain marrow of the girl.

"There's no need, grandpa. I'm fine. Placing her hand on her chest, the girl opened her eyes.

Then, with a slip of her finger, she plunged her finger into her heart, reaching deep into her nerve and pulling out a worm.

"Ahh!!h The bugs screamed in fear and confusion.

The girl who reached out and dug into her heart smiled casually.

"What...... What, what are you doing, Sakura ......" the ugly bug writhed hard.

With a godless gaze, the girl observes the insect that is a grandfather, called a grandfather, and looks like a grandfather.

"What~~~~ Actually, it's really simple~~~~~~ I, I thought grandpa was even bigger~~~~~" The girl sneered and shook her head.

In fact, the real insect body of the Tung Dirty Inkstone is not so short. In order to parasitize the girl's heart, the old magician switched to this more suitable bug. Because it has to inhabit the heart, it must be able to conform to the heart. Looking back, this strange hobby was the failure of the old magician.

Sakura...... Cherry...... Could it be ......" the bug seems to have thought of something.

"I'm really grateful to Ueya-san. If he hadn't smashed my grandfather with the holy sword first, I'm afraid I would have been eaten by my grandfather. “

was seen through. No, this matter, the fight has been decided from the beginning. The old magician did not hide his purpose, and the maiden did not go against the old magician's will. So no problem at all. For the old magician, sooner or later the girl's flesh would become his.

So, the girl waited for the opportunity to rebel against the old magician.

"Wait, wait, wait, wait, wait!!" The old magician is making his last struggle.

"No, you're mistaken, Sakura! Possession of you is a last resort. If you are still conscious, the doors will all be given to you. The old decay only needs to glorify the bloodline of the Kiri. ”

"As long as you become the victor and have everything in your hands, that's it, Sakura!" The bugs writhed hard.

The girl smiled gracefully at the filth pinched by her fingertips.

"That's better~~~~ Because, there is no need for grandpa anymore. Next, I can open the door by myself. “

"Wait, wait, wait, Sakura!"

"Rotten for you!? How can there be a foolish thing that will take revenge......"

"Goodbye, grandpa. I've been living underground for 200 years, I guess I'm tired, right? The girl let go of her hand, and the worm fell to the ground.

"Come on, it's okay to disappear already."

"Poof~~~~" The girl stomped heavily on the thrown bug......

At this moment, only the maiden was left in the altar. The swaying black flame celebrates the independence of the girl.

“…… Whew" the black girl stared at the blood stains on her palms.

"Huhu............ Huhu, ahahahahahaha~~~~~~~haha

"In the end, it was taken away by my sister...... Come on...... Let's break it off......" The girl laughed miserably, clenching her fists tightly.

Night, Liudong Temple

The Ryudong Temple, which sank into the darkness, is like a giant sitting cross-legged, and one can feel some kind of abnormal power. Listen and you'll hear the roaring atmosphere.

"Is this it?" Kamiya looked at Tosaka next to him, yes, it was just the two of them at the moment.

"No, not at Liudong Temple. The upper field is just a superficial door for the Master who wants the Holy Grail. To get to the Great Grail of the Holy Grail War, you have to go not above, but below. Leaving the stairs, Tosaka walked into the forest.

Brushing aside the branches, Kamiya and his party walked in the mountains at night. There is not even a path for animals to walk in the mountains, so they can only walk on the rocks that look like cliffs.

"Hmm...... According to what Illya said, it's probably around here, Upper Valley~~~~ Have you seen a place similar to the entrance? Rin looked around suspiciously.

"What does it look like at the entrance?" Upper Valley knows where the entrance is.

"It's like a rock crevice that people can walk into, or a strange shrine. No matter how you say it's the entrance, how can there be no camouflage. Rin searched the surroundings.

"It's ...... here" Rin suddenly pulled Kamiya and walked up a small stream.

The source of the creek is overlapped with several rocks, and there is only a gap for one person to enter sideways. The rock is made like a cave. At first glance, it looks like you're going to hit a rock as soon as you walk in, but you didn't expect it to really let people in.

"Saber follow closer." Kamiya took Saber and Rin's hand at the same time, and the three of them moved slowly like this.

Gradually, the path that can only be moved forward one by one becomes a walkway to the depths.

There is no need for light at all. Some kind of glowing moss illuminates the cavern in a dark green.

Tosaka walked towards the depths of the walkway, the source of the dark air. Ueya and Saber also walked forward while guarding their surroundings.

The cold wind tore at his cheek like a knife. After passing through the walkway, a wide cavity appears.

The size is about the size of a school playground. Although it was dark and unclear from above, it should be about ten meters high. There are no signs of life at all. This forgotten underground space resembles the moonlit wilderness that I once saw in a book.

There, a blonde man in a black leather jacket and black pants turned his back to the crowd.

"Here we are, boy." The blonde man looked back.

"Although this location is very undesirable to me, but in order to wait for you, this king can only deign to stand here."

"......" Rin gritted his teeth and pulled out the holy sword behind his back.

"Don't be mistaken~~~~~ woman~~~~~" The blonde man didn't look at Rin at all.

"This king is standing here for the young man next to you, and you are not qualified enough ~~~~~~~~~~ quickly disappear from this king." The blonde man waved his hand in disgust.

"Upper Valley...... I don't know what you're going to do, but I trust you! If you really want to save Sakura...... Just don't put it off too long. "Obviously, there is an extremely powerful hero king on the other side, but Rin still said this to Kamiya.

"Hmm!" Kamiya nodded, tacit understanding, no need to say more.
