In this crossover anime, Yoshikage Kira longs for a peaceful life.

"Quiet."

The man's voice seemed to possess a special magic, silencing Ying Xizi who was screaming and questioning the true form. Even her originally ferocious expression gradually returned to calm—mainly because the pink cat choking her neck was very convincing.

The big pink cat grabbed her by the neck and forcibly lifted her in front of Geng Xizi.

Despite possessing immense spiritual power capable of destroying the entire school and killing everyone in it in an instant, the dark-skinned girl offered no resistance, instead allowing the pink cat to manipulate her like a rag doll.

Like Yuko, her heart was also filled with fear.

“Look at her.”

Kira Yoshikage gripped Yuuko's pale chin, forcing her gaze to be level with Yuuko's, his tone as calm as ever, "Take care of her. Or, I'll take care of her for you."

"me……"

Geng Xizi's voice was intermittent, and she was unable to answer for a long time.

Even though it's another version of her, can she really solve the problem with her own power alone?

She had absolutely no ability to resist in front of her!

"It seems you've chosen to let me help you."

Kira Yoshikage's eyes were expressionless, devoid of joy or sorrow. He did nothing. He simply extended his palm, raised his thumb, and then gently pressed it down.

Snapped!

"no, do not want……"

Yuko screamed and grabbed Yoshikage Kira's hand, stopping his thumb from pressing down. She pleaded frantically, "I... I'll handle it, it just needs some time, give me some time, I can do it..."

Kira Yoshikage quietly gazed at the pleading girl's small, pale hands, and slowly uttered a single word:

"5..."

"5 days?"

A new hope was ignited in Geng Xizi's heart.

"4..."

Geng Xizi's eyes immediately turned to horror. Five seconds? What's the difference between that and not giving her a chance at all?

"3, 2..."

As the time for the number of records to drop to zero approached, Geng Xizi became increasingly panicked, while Ying Xizi's expression remained remarkably calm.

It seems they had anticipated this scene.

Even until the very last second, Geng Xizi's mind remained blank; she still couldn't think of any way to solve the problem.

In the end, the girl could only use the one thing she knew how to do, and the only thing she was good at.

"sorry!"

Geng Xizi bowed deeply, gritted her teeth, and shouted, "I'm so sorry."

"It was my fault for pushing everything onto you. It's all my fault. If possible, please give me back those painful memories. I... I will take full responsibility for this!"

Despite Yuuko's apology, Yuuko's expression remained unchanged, and she murmured softly:

"why?"

"Huh?"

Geng Xizi looked up and asked cautiously, "What do you mean..."

"Why won't you let me die? Let me die with your pain and despair, with your tragic memories."

"You can end all of this by abandoning the past, just as the past abandoned me."

"You can still become a radiant deity, standing in the shrine built for you, receiving the reverence and offerings of the world."

"Isn't this better?"

Geng Xizi's cherry-colored lips turned abnormally pale, devoid of any color.

"I know, of course I know..."

Whether out of fear or guilt, Geng Xizi's voice trembled with a hint of sobbing.

But what could she do? Run away again? Abandon her own shadow once more?

Can this really solve the problem once and for all?

If we keep running away this time, what about next time? And the time after that?

Do I have to run away every time?

Does it mean giving up a part of yourself every time?

In the end, was she the one left, or a monster that had nothing left?

Ying Xizi's expression was incredibly calm, but her heart was still filled with hatred—hatred for this world, hatred for everything! Because she was ultimately just the embodiment of all of Geng Xizi's negative emotions and despair; she was born carrying hatred, and only hatred.

Geng Xizi's apology only makes her nauseous!

"Three days."

The Assassin Queen released her grip on Ying Xizi's neck, her cold words carried on the wind to their ears.

Ying Xizi silently lifted the barrier around them. The dark barrier melted downwards and disappeared into the lake, which in turn gradually vanished. The lush grove of trees, which had witnessed the youth of many students, returned to their sight.

"Yo-ga-da!"

Geng Xizi patted her chest and breathed a long sigh of relief.

Three days should be enough, right?

"idiot!"

Ying Xizi's cold words made Geng Xizi somewhat annoyed, "Even if it's another version of me, isn't that going too far? I'm the one who saved you!"

"help me?"

Ying Xizi's expression returned to calm, and she said softly, "Perhaps this is for the best. Let us die together."

"Ok?"

Geng Xizi's wine-red eyes were filled with disbelief. What did she mean by dying together? She didn't want to die at all!

-----------------

Inside the abandoned activity room, extra tables and chairs were piled high at the back of the classroom, leaving a large space in front of the classroom, where only an elegant girl sat alone in the middle of the classroom.

When Mai Sakurajima found the address, this was the scene she saw.

She has a dignified appearance, translucent white skin, long black hair that reaches past her shoulders, and a face that is so cute it's almost unfair.

Although her chest was as flat as the Kanto Plain, she had long, well-proportioned limbs, a perfectly slender waist, and a flawless body curve. She had slightly wavy black hair, crystal-clear and delicate skin, bright eyes, thin cherry-colored lips, and red ribbon bows tied on both sides of her hair. In addition to the uniform she wore with everyone else at school, she also wore black over-the-knee socks.

Without a doubt, even by Mai Sakurajima's standards, she had to admit that this was a beautiful girl who was no less beautiful than herself.

Yukino Yukinoshita raised her hand to smooth her wind-blown long hair and asked softly:

Is there anything you want to tell me?

Mai Sakurajima didn't answer her. She walked to the back of the classroom and wanted to get a chair, but didn't know where to start.

But the next second she saw a chair automatically float down from above the pile of tables and chairs and land next to Yukino Yukinoshita.

Mai Sakurajima didn't mince words. She walked back to Yukino Yukinoshita's side, sat down beside her, and whispered:

"Kira-kun went to meet Yuuko and another woman I didn't recognize in the grove near the school building... Then, the area was shrouded in a visible 'black mist.' I couldn't see what happened inside, but I saw Kira-kun leave from there, and then the black mist suddenly disappeared, and Yuuko-san turned into two..."

Despite Sakurajima Mai's best efforts to describe things in complete sentences, she ultimately couldn't articulate what she couldn't understand. This made her narration seem somewhat incoherent and completely incomprehensible to the average person.

But Yukino Yukinoshita was no ordinary person; she quickly understood what Mai Sakurajima was saying, and her voice was clear and bright:

"That's a domain."

"Domain?" Mai Sakurajima murmured to herself, pondering its meaning.

The girl with long, straight black hair spoke softly:

“Domains, barriers, seals… no matter how the names change, their essence is the same: they are all manifestations of psionic energy.”

Mai Sakurajima seemed to be deep in thought. She had read some novels and could understand this kind of setting, which was absurd but also 'reasonable'.

She quickly raised her own question:

What exactly is psionic energy?

Yukino Yukinoshita closed her book, her sapphire-like eyes gazing quietly at her, and softly asked, "May I ask you something? Do you know about idealism and materialism?"

"Please don't treat me like an idiot."

Mai Sakurajima was a little annoyed. Although she hadn't really attended school for many days, she wasn't that ignorant!

Snowfall remains noncommittal, offering a soft explanation:

Materialism holds that matter is primary and spirit is secondary; the origin of the world is matter, and spirit is a product and reflection of matter. The world we live in now is built on the foundation of materialism.

"Idealism holds that spirit and consciousness are the primary nature of the world, and matter is the secondary nature. In idealism, spirit is the foundation that determines everything."

"If you ask me what psionic energy is, I cannot explain its nature."

"All I know is that psionics is the cornerstone of idealism and has the power to rewrite all of reality."

The girl opened her palm, and a wisp of blue energy floated at her fingertips.

With a gentle flick of her finger, the wisp of energy transformed into floating air and flew towards the table placed by the window, silently merging into the cup of red tea on the table.

In the blink of an eye, the steaming hot black tea was instantly frozen, the liquid inside completely solidified into ice!

Yukino Yukinoshita waved her hand slightly, and the cup of black tea flew into her hand automatically, still steaming.

Mai Sakurajima had already witnessed far more outrageous scenes, so she wasn't particularly shocked. She asked softly:

"So, how do I use psionic energy?"

Yukino Yukinoshita looked at her and suddenly sighed:

"Didn't I already tell you? Psychic power is the cornerstone of idealism, so the way to use psychic power is, of course, idealistic."

"Idealism?"

Sakurajima Mai looked bewildered. What's the difference between saying nothing and saying nothing?
