To be honest, Al now can't really distinguish the boundary between the two treatments. There is only one idea in his mind - treatment, treatment, treatment!

Kagome turned around suddenly, and the strong obsession from the Heroic Spirit was being transmitted to him continuously through the Command Spells.

Treatment, treatment, treatment...

The patients need my treatment, please let me do something for them!

I need magic!

Xia Youjie was shocked by the strong obsession of the Heroic Spirit. His mind was shaken and he set his eyes on the Three-Strike Command Seal on the back of his hand.

"roar--"

He kicked over the cursed spirit that was about to get close to his face, and decided to respond to Berserker's obsession and try the legendary Command Seals. He endured the shame brought by his clichéd lines and shouted, "In the name of the Command Seals, Berserker, go and heal them!"

As he finished speaking, the outermost stroke of the Command Seal disappeared, and only two of the three strokes of the Command Seal on the back of his hand remained.

Al couldn't describe what he felt at that moment. The disappearance of the Command Spell turned into a surge of magic power that immediately filled his body. He stretched out his arms and shouted:

"Bacteria, diseases, pain, I will never forgive any harmful things on this earth! I will do my best to lead people to happiness!"

A huge white nurse phantom appeared behind Al. They were a man and a woman, but had similar faces. At this moment, the two nurses, one big and one small, had the same expression on their faces: kindness, determination, madness, and holiness.

The white phantom raised the pure white sword in its hand high and slashed at everyone including Ieiri Shoko.

Al shouted: "——Destroy all harmful things!!!"

The giant sword came chopping down on their heads, and ordinary people couldn't help but scream in fear. Some were so scared that they dared not move, and some tried to climb out in a panic. Meiming waved his cursed tool to block the giant sword, Ieiri Shoko and Iori Utahime also subconsciously used cursed power to defend themselves, but the white sword easily penetrated all their defenses and smashed heavily on everyone's head.

Boom——!

The giant sword shattered into tiny points of starlight, which entered people's bodies along the wounds. In the blink of an eye, all the wounds disappeared without a trace, and the people who were originally exhausted immediately recovered their strength after this sword.

Ieiri Naoko widened her eyes.

What is this?

This is not a reversal technique!

More cursed spirits were attracted by the screams and rushed over here. After releasing the treasure, Nightingale turned around and pulled out a pistol from his waist.

Amid the doubtful gazes of the crowd behind him, he said firmly: "Even children who don't like injections still need my treatment!"

"anaesthetization!"

"disinfect!"

"first aid!"

"Heart Resurrection!"

There were continuous gunshots coming from the parking lot. The nurses in red military uniforms stood firmly in front of everyone, fighting with their remaining magic power. Seeing that his help was not needed there, Xia Yujie confidently handed the place over to Al and began to clear the cursed spirits from bottom to top.

It didn't take long for Gojo Satoru to defeat the cursed spirit boss on the rooftop and began to sweep from top to bottom. After forty minutes, they finally cleared all the cursed spirits from the entire building.

"Experience +10, experience +10, experience +10..."

"Level up to lv.42"

"Low battery warning, low battery warning, low battery warning—"

The system in his mind kept sounding the alarm. Al, who was under the influence of the Command Spell, was unable to stop consuming his magic power in a timely manner. By the time the madness in his mind subsided a little, Gojo Satoru and Geto Suguru rushed over to meet him, Al's battery power had become precarious.

"Berserker...you..."

When they saw the unsteady Heroic Spirit, they couldn't help but show surprise.

Al blinked hard, and relying on the heroic spirit's instinctive desire for magic, he said to Geto Suguru: "I won't fall... I will never fall... Master, I need... magic..."

"Magic...Berserker? Berserker! Hey, Berserker!"

Al's figure turned into a spirit on the spot and disappeared before their eyes.

"Berserker!!!"

…

When Al came to his senses, he was in a white space. He was no longer wearing Nightingale's COS costume, and his frenzied brain finally returned to normal.

He sat in this space for a while before he suddenly came to his senses: "System?"

"Host. Your remaining power is less than 1%. The system has no choice but to forcibly transform you into a spirit."

Al was surprised: "...What is going on? Who are you? How can I really become Nightingale?"

"You have not only merged with Berserker's power, but also their crazy thoughts. Since your previous mental state was not normal, many things cannot be communicated normally."

Al thought back to what he had done that day and found it quite incredible.

At that time, he seemed to have really become the heroic spirit Nightingale. Not only did he really possess powerful strength, but he also inherited Nightingale's strong will.

If he remembered correctly, he seemed to have forcibly demolished the rooms of two male high school students... Nightingale, he actually "COS" Nightingale!

The angel in white, Nightingale, her strength, her belief, her persistence, her madness... The soul of the hero seemed to still be burning in Al's chest. Al stroked his heart, unable to describe his feelings at the moment.

During the time when he was possessed by Berserker, he was so close to Nightingale, so close!

The system decided to follow the procedure of the first meeting and reintroduce itself: "Hello host, welcome to the COSER binding system. I am your binding system 007. According to your own situation, system 007 automatically adjusts to the Berserker COS system. After testing, it chooses the world that best matches you to cross."

The world with the highest degree of compatibility...

Is this the world of Jujutsu ○ War?

"As a time traveler with the COS system, please use your cheat code to change the fate of ten important characters in Jujutsu ○ War. After completing the task, the system can fulfill one of your wishes."

"…My wish?"

"Yes, the system will do its best to fulfill your wishes within its capabilities. The conscientious system does not make false propaganda, does not maliciously distort the wishes themselves, and ensures that the wishes made by the host are exactly the same as the wishes realized!"

Al: “…”

This system is obviously a veteran one.

As an old player of Chaldea, he really doesn't believe in the so-called "universal wishing machine", and the system's supplementary explanation is just right.

"After signing a formal contract with the system, the system will unlock a designated Heroic Spirit vest for you free of charge. You can choose one of the remaining four Berserker vests as a novice benefit. The power will be automatically replenished after switching identities."

"But seriously, if there really was a Holy Grail War in this world, have you thought about what wish you would make?"

"Skip straight to the wishing part? You really are so confident of winning."

"Of course. You and I are the strongest. And we have our invincible nanny, Nozomi. How could we lose? We defeated all the enemy Masters in seconds."

The voices of Gojo Satoru and Kagome Kagome came to Al's ears, and the air seemed to be filled with the smell of fried chicken, miso soup, and grilled fish...

So hungry!!!

Ieiri Glass Road:

"Pfft, I say, Gojo. Maybe in a few days the Command Seal of the Lord will appear on the back of your hand, and then you and Geto will be enemies."

"No." Gojo Satoru said calmly, "I don't have any wishes that I want to fulfill with the Holy Grail. Even if I really join the war as a Master, I will definitely help this guy."

Xia Yujie's voice sounded a little moved, "Satoru..."

"Tell me, if there really is a Holy Grail, what wish would you make?"

"Um... world peace? Love and peace?"

Two classmates: "..."

"Hahahaha, it really doesn't work? Then make a wish to destroy all the cursed spirits in the world."

Ieiri Naoko complained: "These wishes are very 'Summer Oil'."

Gojo Satoru also agreed: "Ha, it's just very 'Sugar Oil', so boring."

Xia Yujie said angrily: "Do you believe I will beat you up? Wait, I got it, then I will multiply the number of cursed spirits I currently have by a hundred times!"

"Wow, you are so greedy, do you really want to overtake me?"

Golden particles suddenly began to condense around them. The three students shut up immediately and watched the spirit particles quickly gather into a human shape.

A blond-haired, blue-eyed boy in school uniform suddenly appeared in the infirmary.

Gojo Satoru: “?”

Xia Yujie: “?”

Ieiri Nitro: “?”

They asked in unison: "Who are you?"

The gathering of spirits just now made them think that Berserker had returned, but the boy in front of them... huh? What's with this boy? Who is he???

The blond-haired, blue-eyed boy looked at the table filled with delicious food and swallowed subconsciously.

Geto Suguru, who was contracted to him, was the first to react.

He was surprised and asked, "You are - Berserker?"

The blond-haired, blue-eyed hero nodded, his eyes still fixed on the table full of food.

The high school students were really shocked: "How did you become like this?"

The Heroic Spirit who changed his skin sat down on the empty chair in front of them. Looking at the table full of delicacies, the boy's green eyes were full of anticipation. He asked pitifully, "Can I eat these?"

High school students: “…”

What's going on? Is this guy really a Berserker? Is his temperament wrong? Why does he feel like a completely different person?

They exchanged glances, and Xia Youjie nodded first: "Okay."

Ieiri Naoko said with a complicated expression: "Anyway, we bought these to replenish your magic."

Al was touched. He picked up the fried chicken closest to him and ate it without hesitation. Well, it would be nice if there was something sweet. Due to some characteristics of the new hero, he was now extremely eager to replenish sugar.

The frail-looking blond boy swept the food on the table at a terrifying speed, and his desperation left the three high school students dumbfounded.

Gojo Satoru whispered to Geto: "Geto, do you think this guy looks familiar?"

Xia Yujie thought in sync and said, "...Blonde-haired, blue-eyed, big eater, and aloof king Artoria?"

"right!"

It really looks alike!

The Berserker in front of me looks exactly like Artoria, the famous feminized King Arthur in the FATE series! Really exactly the same!

“No, wait, Satori, Artoria is a woman, and her rank is Saber, not Berserker…”

Gojo Satoru interrupted, "But the historical King Arthur was a man."

Xia Yujie: “!!!”

Xia Yujie was shocked.

He thinks Gojo Satoru is right. In Fate's worldview, King Arthur is a female, but in their worldview, King Arthur is a genuine male, so the King Arthur summoned from this world is also a male?

It sounds really convincing!

Ieiri Naoko was confused and asked, "Wait, isn't the Heroic Spirit you summoned a nurse? Are you sure this guy is the same Heroic Spirit as the previous one?"

Xia Yujie said solemnly: "The data panel is indeed the same, and the contract connection has not changed at all."

Gojo Satoru, the Six Eyes holder, also confirmed: "Yes, I am also sure that their body data is the same."

Ieiri Naoko looked thoughtful.

She trusted her two male classmates, which made her feel even more confused.

Al, who was concentrating on destroying the food, found that the battery of his Nightingale was increasing very slowly, and the battery of "Mysterious Heroine X.Alter" he was using was completely full.

The vest that Al chooses to unlock is the gender-swapped version of "Mysterious Heroine X.Alter", also known as Crazy Daze.

"When the battery of the currently used vest is full, the extra mana will be added to the batteries of other vests, but the speed will be much slower. The host can also try to charge other vests that have not been unlocked. When the battery is charged to 30%, a new character can be unlocked."

As for why Kuang Dai can charge other vests...

Al said he had expected this.

Because the Heroic Spirit he is using now - Kuang Dai, is a magical Heroic Spirit with his own "energy converter" that can perfectly convert the absorbed calories into magic power, solving the problem that no one can provide him with magic!

As one of the comedians of Chaldea, Daimo has a face exactly the same as the heroine of FATE, Artoria. When designing the Chinese version of Daimo, Al referred to many other Artoria images and even the male King Arthur, before finally deciding on the final image of the gender-reversed version of Daimo.

By the way, Kuangdai is the first character in Al’s COS career, and his nickname “Al” is also taken from Artoria. Perhaps because of this relationship, his fusion degree with Kuangdai is as high as 97.8%, which is much stronger than Nightingale’s 67%.

The higher the degree of integration, the higher the degree of self-preservation.

By the time Al had almost finished the food on the table and still felt it was not enough, the three high school students had finished a meeting.

"Berserker." It was Geto Suguru who spoke first. He asked in a deep voice, "You look different than before. Why is that?"

Al pretended to be dumb and asked, "What's the difference?"

"...Huh? It's different in every way, right?"

“No.”

"...No?"

Al nodded seriously: "Yeah."

Xia Yujie: “…”

"Tsk." Gojo Satoru pushed his useless best friend aside and said excitedly, "Hey, Berserker, now is the time for quick questions and answers. Please answer quickly - what is your current name?"

"Al."

Al wiped his mouth, and contrary to Nightingale's taciturn personality, he spoke nonstop:

"I am the mysterious hero from the universe, X. Alter. I am the king of the galaxy, and I was raised as a proud knight since I was a child. Hiccup, do you have any food?"

Three high school students: "..."

They each exchanged looks that said, "What nonsense is he talking about?", "Is he a little mentally ill?", "As expected of the legendary Berserker."

Ieiri Naoko glanced at the messy table and asked, "You've already finished your food, but you're still not full?"

Al shook his head and said in a flat voice:

"I am growing up and I must eat well to grow taller. If there is really nothing to eat, I suggest you place an order at Galaxy Amazon. They will deliver red bean paste buns and daifuku at lightning speed. Please, please make sure I am full!!!"

Three high school students: "..."

This guy - what the hell is going on?!
