Type-Moon's Problem Child from Collapse

This magical fluctuation and emotional composition—if I'm not mistaken, it should be those two. But did they fight today?

Looks like the butterfly's wings have started flapping. Tch, things are about to get troublesome from here on out.

"Let's go in and take a look, A Yuan." Irisviel still remembered her original goal—victory in the Holy Grail War.

She couldn't afford to miss something like this, even after what had just happened.

"...Mm." Fu Yuan was a bit surprised. Even though Berserker's group was almost certainly inside, given what had just occurred, he'd genuinely planned not to enter, out of consideration for Irisviel's feelings.

Fu Yuan's gaze softened, but on second thought, he could understand how Irisviel was thinking. 'More and more heartbreaking, Irisviel.'

After that, the group didn't break the magical wards here—after all, some surface-level formalities still had to be maintained.

Just a few steps forward on the street, and the scene was completely different from the sunlit outside. It was like stepping into another world.

Blood dripped from the walls—some fresh, some nearly dried. The street was littered with shattered chunks of flesh, and at the center stood a pitch-black knight who had just stopped, along with some monsters frantically retreating?

Fu Yuan: How to put it? 'I walk in and the first thing I see is Changwei beating up Laifu.'

"Berserker!" Irisviel exclaimed in surprise. Judging by the magical formation outside, she'd guessed Caster was inside—but what was Berserker doing here?

Was Caster insane? No matter how high his rank, this magical formation had only just been set up. Charging head-on at the highest-stat Servant, Berserker—how desperate did you have to be?

'An opportunity.' Gilles de Rais spotted the newly arrived Saber Group and his eyes lit up. Grabbing Ryunosuke Uryu, he charged straight toward them.

'Damn it, that guy turned out to be Berserker's Master. But no matter—as long as Lord Evil God is pleased, none of this is a problem.'

The moment Gilles de Rais thought this, his heart eased. Staring straight ahead at Saber, he summoned a few more Sea Demons to block his path. 'If I can hold Saber off for just a moment, I can break out. Out on the street, they won't dare make a move.'

Kariya Matou's expression darkened as he watched their actions. If they broke through, using this Command Spell of his would be completely meaningless.

"Berserker, don't let him—"

"Heavenly Fire: Unsheathe!"

But before he could finish, a pillar of blazing fire erupted before his eyes. Scorching heat surged forward, and even the dried blood on the walls evaporated instantly. It was as if the whole world had been swallowed by a sea of flames—then vanished just as quickly, as if nothing had happened.

The Caster Group, caught at the epicenter, was obliterated in that single strike. The Sea Demons and tentacles he had summoned were all burned to ash.

Illya: So cool!

Irisviel: Was that a Noble Phantasm release?

Void Sword Qi was different from other Cultivation Methods. Its essence was making better use of Honkai energy. It didn't advocate pouring Honkai energy into the body—its sole purpose from start to finish was to better harness the energy between heaven and earth to achieve one's goals.

Even weakened to its current state, controlling a Heavenly Fire that wasn't fully unleashed was more than enough. That was why Irisviel and Illya still had the leisure to think about other things.

Heavenly Fire Self-Destruction was no joke. Almost every head of the Caslana Family had been burned to death using it.

"Hello, Lancelot. And hello, Kariya Uncle and little Sakura."

Fu Yuan casually withdrew Heavenly Fire Self-Destruction, then took the initiative to greet the somewhat flustered Berserker, who was caught off guard by the sudden turn of events.

Kariya Matou shielded Sakura more firmly behind him before relaxing enough to look at the Saber Group that had appeared out of nowhere.

"Your Excellency, is there something you need? If not, we'll take our leave."

Irisviel snapped out of her earlier confusion. Seeing how wary Kariya Matou was, she suddenly felt that forming an alliance would be troublesome.

"Need an alliance, Kariya Uncle?" Fu Yuan didn't seem to find it troublesome at all. In fact, he acted as if he hadn't heard what they said, keeping his smile as he asked.

"No. Can you move aside now?" Kariya Matou assessed his own condition. After that fight, his body was even more drained—very bad.

"My ability can improve other people's bodies!"

Fu Yuan suddenly spoke up just as they were about to leave from the other side. Watching Kariya Matou freeze in place, he felt an inexplicable sense of amusement.

Just wouldn't say it directly. Just playing around!

"What do you mean, Saber?" Kariya Matou suppressed the hope rising in his heart, forcing calm into his voice.

Then he patted Sakura's head and silently communicated with his remaining two Command Spells.

"Literal meaning. Oh, and it improves from the very source!"

Fu Yuan still spoke in that cheeky tone.

"How do you prove it?" Kariya Matou asked a very serious question. This question would decide whether they fought or stayed.

Fu Yuan blinked. Paused. Blinked again. Then blinked once more.

"How do I prove that?"

Kariya Matou seemed to suddenly realize something too. He glanced gently at Sakura, then walked straight over.

"Use my body!"

Berserker loyally followed beside him. But at this distance, Fu Yuan could kill him dozens of times over. What an idiot!

Shaking his head to set aside those stray thoughts for now—if they really did form an alliance, things would get a lot easier from here.

Fu Yuan didn't make any other demands. He simply stood on tiptoe, placed his hand on Kariya's head, and pushed the Stigma to full power.

As for why the head? Because it was fun!

Then Kariya Matou started to regret it. Sure, improving his body was a good thing—but this was way too comfortable! He wanted to moan! And Sakura was right there watching! But he couldn't move! He could only use his eyes to signal the Saber, who was standing on tiptoe and still a bit shorter than him.

Fu Yuan seemed to catch his meaning. Then he silently cranked up the power.

"That's not what I meant!"

"Mm~hm."

"It's over. My spotless reputation—what will Sakura think of me?"

Fu Yuan withdrew his small hand, patted it with satisfaction, and looked at Kariya Matou, whose face was frozen in despair, asking as if he had no idea what was going on.

"What's wrong, Kariya Uncle?"

Kariya Matou trembled slightly as he glanced at him, but in the end, he lacked the courage to turn and meet Sakura's gaze. Finally, he gave in to self-abandonment.

"No fun left. Let it all burn."

Fu Yuan suddenly remembered something he had overlooked, his eyes lighting up as he put on a look of great curiosity.

"Is that another line from Dark Magic Swordsman Kariya?"

Hearing this, Kariya Matou stopped trembling entirely. He stared at Saber in utter disbelief. A few seconds later, a wave of despair washed over him.

"How do you know that?"

"I took it from Zouken Matou in the future!"

Fu Yuan blinked innocently, his childish tone casually dropping a bombshell of information.

"Zouken Matou..." Kariya Matou struggled to process this. That meant the old bastard had a backup of the most cringe-worthy, most embarrassing period of his life—the stuff he wanted to forget most.

"That old worm has to die!"

Chapter 21: This Is Youth!

"Who dares claim invincibility? Who dares boast of undefeated? Not even in the Emperor Fall Era!"

"Him—just a measly old worm—daring to covet immortality!"

"Even if my Spirit Core is damaged, even if I must be wary of that petty Alaya, I remain unmatched in this world!"

"Ahem... Saber, are you sure about this?" Kariya Matou watched as Fu Yuan indoctrinated Sakura with all sorts of strange knowledge, feeling a strange surge of excitement inside.

Suppressing the embers of his long-dormant chuunibyou spirit, he calmed himself and interrupted Saber's "preaching."

After all, the person they were about to kill was his own father. He had to plan everything perfectly—no mistakes allowed.

"One Sword Breaks Ten Thousand Ages, One Age One Cycle—what have I to fear?"

"...Mrs., is Saber going to be okay?" Kariya Matou suddenly felt a pang of panic. This Saber seemed... unreliable.

Irisviel, who had been carrying a heavy heart, found herself relaxing a little under the barrage of absurdity.

Watching A Yuan—whether he was joking or speaking from the heart—she inexplicably felt her mood lighten, even though they were about to face a monster who had lived for over two hundred years.

"It's fine. Try to trust A Yuan as much as you can."

"In this world, there is no absolute right or wrong. The victor is king—that's the only truth."

Irisviel's lips twitched. That might be true, but some of his words were completely beyond her, and that was frustrating.

Kariya Matou watched Sakura, who was being dazzled by the nonsense, and found it oddly heartening. He didn't stop it—having any emotional reaction was a good sign.

But that didn't mean he wouldn't try to clarify things, to keep his dear little Sakura from turning into someone who spoke in riddles.

"What Saber means is, you won't believe something until it's done."

Fu Yuan shot him an unexpected glance. No wonder this guy wrote Dark Magic Swordsman Kariya.

"You are worthy to speak my True Name, mortal."

Irisviel's face filled with confusion, and she turned her gaze to Kariya Matou.

"...Saber means he acknowledges you. In chuuni—" Feeling the weight of her stare, Kariya Matou sighed but dutifully translated, stopping mid-sentence. Damn it, why did I let that slip?

"Chuuni? Is Uncle a weird person too?"

Little Illya, who had been ignored until now, suddenly chimed in, her big eyes blinking as she stared at Fu Yuan and Kariya Matou.

"I'm not, I—"

"One who acts without evasion, whose heart knows no fear—that is the path a true strongman walks." Fu Yuan cut Kariya Matou off mid-sentence, declaring his opinion with arrogant flair, then shot Kariya a look of faint disdain.

Kariya Matou: I really want to hit him. For real.

"Can Big Brother kill Grandfather?" Sakura, who had been absorbing all the strange knowledge, hadn't understood most of what he said, but she had caught the key points.

A glimmer of hope flickered in her hollow eyes. If he can... that would be... so wonderful. She thought happily.

Fu Yuan looked at her empty gaze and felt a rare pang of sympathy, but he still answered with bravado: "A single flash of cold light, ten thousand miles of radiance—what does it matter if I slaughter the whole world?"

Seeing something expand in Sakura's eyes, Fu Yuan sighed inwardly. What did she have to go through to end up like this?

"Mm." Sakura didn't understand the meaning of his words, but she grasped the emotion behind them.

She nervously tugged at the corner of Fu Yuan's robe, then quickened her little legs to keep pace with him.

Is this Junior Brother's method? A cold voice echoed in his mind. A simple question, yet it sent a chill down the spine.

Life is long, and most are just passing guests. When the guest leaves, the tea grows cold. What is Senior Sister worried about?

"Then, by accident, the guest becomes the master?" The voice still sent a chill down one's spine, but it seemed much better than before.

"How could that be? Senior Sister knows me well enough."

"It's precisely because I know you're a lolicon that I said that." The voice in his mind suddenly grew a bit impatient, even forgetting it was still angry.

"Mm~ At least Senior Sister is here!" Fu Yuan, hearing the sudden shift in tone, quietly breathed a sigh of relief. Anger was fine—as long as it wasn't outright ignoring him.

"Hmph!" The figure within the Stigma seemed to suddenly realize something, growing somewhat displeased, but said nothing more.

To the onlookers outside, it looked like Saber had suddenly stopped, then after a few seconds, visibly brightened up as if possessed by a ghost—or perhaps having a seizure.

"When the fiery mulberry blossoms all fall, the beloved departs and chaos stirs, with golden spears and iron horses, where in the world is home."

Irisviel once again turned her gaze to the translator, Kariya Matou, while the two little ones beside her mimicked her with serious expressions.

Kariya Matou felt as though his reputation was utterly beyond repair, and all because of what, exactly?

Though his inner thoughts were quite tangled, he still dutifully fulfilled his role.

"Saber is probably just playing around, nothing meaningful."

Irisviel looked at him with admiration. 'Amazing, he can understand that!'

The two little ones seemed half-comprehending, but still gazed at the newly appointed translator with admiration.

'Damn it! I don't want this kind of admiration!'

"So this is the birthplace of sin, truly filled with filth and decay." Fu Yuan was clearly still immersed in his role; chuunibyou was like crossdressing—only zero times or countless times.

"Mm, it's up to you now, Saber." Kariya Matou held Sakura's hand with one arm, stopping her from moving forward, while looking at Saber with utmost seriousness.

After being held back, Sakura stopped advancing, but her eyes stared at him with great anticipation.

Fu Yuan found it somewhat troublesome. After all, if he went in alone, he couldn't rest easy about Irisviel and Illya.
