After unlocking all CGs, a Type-Moon girlfriend comes knocking.

Rider's expression was calm as he said, "The Holy Church sent people to Yuanzang Mountain last night to re-arrange the Great Holy Grail's purification barrier."

Matou Sakura raised her head, gazing towards Mount Enzo, or rather, the direction where the Greater Holy Grail's core was hidden, and whispered, "This must be news from Einzbern Castle... After all, that mother and daughter are inextricably linked to the Greater Holy Grail."

"What's next?"

Rider asked.

"The Greater Holy Grail cannot be purified in any way."

Matou Sakura stretched out her right hand, and in her palm, a bug with extremely complex patterns quietly emerged.

Feeling the extremely dangerous and terrifying aura, Rider couldn't help but whisper a warning: "Sakura, be careful... This thing is not something you can control."

"Do you know what this is?"

Matou Sakura looked at her Servant with a little doubt, her usually bright eyes now seemed a little dim.

"...Anyone familiar with Mesopotamian mythology would probably be familiar with it."

Rider said darkly, "It's the nightmare of Mesopotamia."

From the black mud of the Indian Ocean.

——The tide of chaos.

"It won't affect my will. You just need to be careful."

Matou Sakura smiled and handed the "Marking Bug" to Rider.

"Send it to the Greater Grail."

"...Until that thing comes out, the Greater Holy Grail cannot be completely purified."

Logically speaking, all Masters from all sides participated in the Holy Grail War for the almighty wish-granting machine. However, Matou Sakura was not there to make a wish from the very beginning.

Rider hesitated slightly, but finally lowered his head: "I understand."

She took the Marking Bug that was affected by the Chaos Tide, turned around and left quietly.

Sakura Matou raised her head and looked at the snowflakes in the sky. She placed one hand gently on her full and upright chest and soon exhaled a sweet breath.

"Don't worry, just wait a little longer... Soon, very soon we can be together forever, Senior~"

Half of her long black hair seemed to be dyed into a flowing starry night, and the tips of Matou Sakura's hair seemed to be burning with the eternal flame of Gamma-ray.

……

Tohsaka family.

The bathroom was filled with mist and hot steam rose from the bathtub.

Wow...

Toosaka Rin lightly tapped the water surface with one foot to test the water temperature, and then slowly sat down in the bathtub.

The hot water in the winter night soaked her body, as if all the fatigue of the day was swept away. Toosaka Rin couldn't help but let out an intoxicated sigh.

But soon, as if she thought of something distressing, she quickly opened her eyes, and there was a hint of worry in her beautiful blue eyes.

"I wonder what kind of Servant Sakura will summon..."

"She's already a mature child. You can't take care of her forever... Maybe you can try to trust her sometimes."

At this moment, the boy's voice suddenly came from outside the bathroom.

"Assassin?!"

Toosaka Rin seemed startled, subconsciously covering her chest and looking at the hazy figure outside the bathroom: "You, why are you here?"

"Tonight is the first night of the Holy Grail War. The identities of the Masters of each side are still unknown. I cannot leave your side."

Alvin smiled and said, "Don't worry, I won't go into the bathroom."

"I know what kind of person you are... but it still feels a little strange."

Toosaka Rin lowered her head and muttered again: "And doesn't that make it sound like I have no charm?"

A young girl was taking a bath in the bathroom, but Alvin, a member of the opposite sex, showed no interest at all... It was a bit depressing to think about it.

Alvin was speechless for a moment: "Do I have to come in and peek now to prove your charm, Master?"

"That's not necessary..."

After Tohsaka Rin finished speaking, she couldn't help but think of the 'dream' of last night.

She hesitated for a moment and said, "Assassin... I have a question for you."

"what?"

Alvin asked.

"It's about what happened last night..."

Was what happened last night really just a dream?

When Toosaka Rin woke up this morning, she had been thinking about this question.

The taboo scenes such as how Sakura Matou took the initiative to hug Alvin, and even how Alvin put his arms around his sister's waist, still appear in Toosaka Rin's mind.

If it was a dream, it was a little too clear.

Alvin's heart moved, but his face remained expressionless: "What's the matter?"

"that is--"

Toosaka Rin was about to speak, but at this moment, Alvin suddenly sensed a sweet magic emanating from afar.

He suddenly looked up in a certain direction.

"what happened?"

Toosaka Rin also noticed something unusual.

"There are Servants fighting each other... I can sense their presence."

Alvin's tone was low.

Although he was an Assassin, his perception was still very amazing. In addition, the Servant he was fighting against was probably also very powerful, so he could clearly feel the fluctuation of magic power at this time.

As soon as Alvin finished speaking, the sound of water splashing came from the bathroom.

The next moment, Toosaka Rin, wrapped in a bath towel that outlined her graceful and slender figure, rushed out of the bathroom.

She was tall, with long, wet black hair draped over her back. The water droplets dripping down her fair skin were crystal clear. She lacked her usual elegance and had a bit more of a lazy mess.

"where?"

There was a solemn expression on Toosaka Rin's beautiful fair face.

"Towards Mount Yuanzang... Do you want to go over and take a look?"

Alvin asked.

"Yunzang Mountain..."

Toosaka Rin's eyes flickered slightly. "Could this be related to what Illya said about the destruction of the purification barrier?"

She hesitated for a moment, then made up her mind: "No matter what, this is a rare opportunity. Perhaps I can use this evening to confirm the identities of the other Servants and Masters."

Alvin hesitated, as if he wanted to say something but stopped himself.

"Assassin, I am your Master after all. I cannot let you go out and gather information on your own."

Toosaka Rin raised her hand and gestured to the Command Seal on the back of her hand, "And in the critical moment, I can also help you, right?"

Normally, one Command Spell is enough to replenish a Servant's magic power. At critical moments, Rin Tousaka, as a Master, can indeed come in handy.

Besides, the other party's personality doesn't seem like one that can be persuaded... Alvin nodded: "Then let's go together, but..."

"But what?"

Toosaka Rin raised her eyebrows slightly.

"Are you sure you want to go out dressed like this...?"

Alvin hesitated.

Rin Toosaka followed Alvin's gaze and looked down at herself. Her pupils suddenly dilated and two intoxicating blushes quickly appeared on her cheeks.

"You go out first!"

After saying that, he turned around and slammed the bathroom door.

Alvin couldn't help but shrug.

Whether it's about failing to keep up or being slow to react, she's exactly like Ishtar...

……

Yuanzang Mountain.

At the foot of the mountain, a girl with loose silver hair stood with her hands behind her back, a pure smile on her face, as she nonchalantly looked at the enemy Rider.

"Caster is right. Rats really do sneak in at night."

"It should be you who destroyed the purification barrier, right, Rider?"

The purple-haired queen smiled faintly. "The connection between the Einzbern family and the Holy Grail is indeed very close. It seems you've noticed something unusual a long time ago?"

Illya didn't answer. She simply stretched out her hands, gently scooped up a falling snowflake, and watched it slowly melt. "Have you finished your last words, Rider?"

Rider's smile turned even colder: "Do you think you can keep me?"

“You’ll know after you try it.”

Illya smiled slightly and said, "But I don't think you can leave."

Before she found Toosaka Rin yesterday, she had already set a trap in advance, waiting for the "rat" to take the bait.

At this moment, he was naturally prepared to keep the other party.

However, at this moment, a third voice suddenly sounded quietly in the darkness.

"It's really lively tonight."

The moment this voice fell, everyone present looked at the same time, and saw a figure walking towards them gracefully in front of the entrance of Yuanzang Mountain.

The accumulated snow crackled with tiny crackling sounds under the pressure of some terrifying magical force, and Illya's gaze suddenly froze—on the snowy ground that should have been empty, an extremely dense magic barrier was quietly forming at this moment, like a predator baring its fangs.
