I am Gilgamesh, the King of Heroes.

The red spear, like a venomous snake, pierced straight towards Jill's heart!

"...Tch...What a terrible guy...wouldn't it be better if he were dead?" But at that moment, Gilles saw the resentment in Cú Chulainn's eyes...

"...Was it at the behest of that wretched priest Kirei Kotomine...? Then let me help you find release!" Gilles flipped his hand and plunged the longsword in his hand deep into Cú Chulainn's heart!

"Clang!" The spear was stopped by the shield just before it pierced the heart...

“…Thank you…” Cú Chulainn looked relieved, then vanished in a shower of phosphorescent light.

stomping on...

Jill took several steps back.

"Kirei!" Gilgamesh's expression turned to fury. "You bastard!"

"Hmph... that annoying priest, he's really annoying." Gil clicked his tongue. "Well then, let's postpone our duel until the next battle."

"Hmph... Although I'm very displeased, this is the only way. Remember, your life can only be taken by me!" Gilgamesh said coldly.

"Hmph, my life won't be taken by a middle-aged, brain-dead, delusional person like you," Jill retorted without hesitation.

"...Tch, little brat."

"Older-onset chuunibyou (middle school syndrome)".

"Tsk... Just you wait!"

So Gilgamesh left.

Ilya tilted her head. "That guy is amazing... I always felt like he was running away in a panic..."

"Ugh... Just thinking about what I might look like in the future makes me want to bang my head against a wall... That guy is so annoying," Jill muttered.

“Yes, yes, I really hate it!” Ilya nodded vigorously and said.

"Ilya, are you alright?" Jill asked.

"Um... I'm fine, thanks to Berserker for protecting me all this time... But... um..." Illya clutched her head, "My head is a little... dizzy..."

“As expected, the souls of the four Servants have become a significant burden.” Jill frowned. “Come here, and gather a few maids; we need to prepare for surgery!”

"Young man... what kind of surgery...?"

"It's alright, Ilya. Take a nap for a while. Everything will be alright when you wake up."

Jill delivered a karate chop to Illya's neck, and Illya's body went limp, collapsing into Jill's arms.

Jill exhaled and shouted, "Get me a clean room, then disinfect it before coming to help!"

He knew there were maids in the castle who could help him.

He was going to help Ilya complete the most important surgery.

Hercules, unusually, did not roar, but instead watched quietly as Gil held Ilya in his arms.

“…Hercules, if you trust me, then entrust Ilya to me for now,” Gilles said earnestly, looking at Hercules.

"..." Hercules nodded silently, agreeing with Gil's suggestion.

P.S.: Book recommendation: "Me, My Mother Shanshan, a Master of Romance!"

Hmm... As the title says, of course, Little En in REC didn't come from there.

Chapter 74 Heart Replacement Surgery

Einzbern Castle.

Jill asked Sera to help him prepare a room that would temporarily serve as an operating room.

“Very well… Now, Sera, you go out and don’t let anyone disturb me,” Jill commanded.

"……Yes."

Sera nodded and left the house.

Jill let out a breath.

“Then let’s begin…” Golden ripples appeared beside Jill’s hand, and from the Gate of Babylon, Jill took out a bright green, crystalline piece that exuded a rich life force.

This is an important tool that Gil obtained by exchanging his power as a former "subject" and the bonds with his partners.

This device can replace the functioning of a human heart.

Moreover, it can increase the lifespan of transplant recipients.

Its name is Fairy Heart.

However, this requires very sophisticated methods.

Jill gently grasped a scalpel.

His brain was working at lightning speed, while the omniscient and omnipotent star was constantly being stimulated by him.

Gurgle...

Because of the continuous use of his brain, Jill felt a slight stinging pain. Actively stimulating the all-knowing and all-powerful star was also a troublesome matter.

Jill gripped the scalpel tightly.

With a swift incision, the heart is separated from the other magical circuits, the fairy heart is inserted, and the magical circuits are reconnected using magic...

In that instant, Jill calculated countless times the angle and force of the scalpel's incision.

The knife strike must be made in an instant, and all actions must be completed within ten seconds.

So Jill began to concentrate.

A moment later, Jill opened her eyes.

The blade was aimed at Ilya's chest—

A flash of silver light—

……

"Huff...huff...huff..." Jill felt a little dizzy from overworking her brain.

But Jill persevered.

Incredible, he just succeeded.

It took just over six seconds to complete all the actions.

However, there were many dangerous moments along the way, and Jill almost cut herself somewhere else with one of her cuts.

But fortunately, the result is good.

Jill used medicine to help Ilya heal her wounds.

"Ha...ha...this time, I finally succeeded...I didn't let life escape from my grasp again..." Jill sat down, exhausted.

While she wasn't physically exhausted, the intense mental concentration left Jill feeling quite weary.

"Phew... I need to go out for a bit..." Jill stood up and pushed open the door...

"Boom!" The huge, ferocious stone sword slammed down in front of Jill.

"..." Jill's face turned pale with fright.

A berserker who unintentionally caused trouble almost achieved what even Gilgamesh couldn't... instantly killing the protagonist.

"My God... what's going on?" Jill frowned, then walked around the stone sword and looked ahead.

A female knight wielding a sword, and a boy with reddish-brown hair.

Hercules is confronting them.

"Hey, isn't this Shirou Emiya and King Arthur? What, are you here to declare war?" Gilgamesh walked forward.

“King of Heroes…” Artoria looked at Gil with murderous intent.

"Hey, don't look at me like that," Jill said casually, adding in a slightly unhappy tone, "Don't compare me to that guy."

“Hercules, your Master is out of danger… Go and protect them,” Gilles said weakly. “Leave this to me for now.”

"..." Hercules stepped back after hearing this.

"and many more!"

"Does the Knight King intend to bully Heracles, who only has one life left, and a helpless girl?"

Gil said to Artoria in a teasing tone.

"Hmm!" Artoria wavered after Gilles said that, her adherence to chivalry was shaken.

"Then how about we have a fight?"

Gil casually waved his hand, a flash of golden light appeared in the space, and Gil gripped the black-handled greatsword, saying.

"King of Heroes...you...why are you appearing here in this form?!"

Artoria questioned loudly.

"King Arthur, why are you here?" Gilles sneered. "What exactly is the Holy Grail in this Holy Grail War? You destroyed it with your own hands, don't you understand?!"

Gilles' eyes flashed. "If you insist on taking the Holy Grail, then your wish will only turn into disaster!"

"How could you, a tyrant, possibly understand my country..."

“…Gawain is right, you are bound by what you consider correct, but King Arthur… there’s an old Eastern saying, ‘To err is human…’ and another, ‘Even the wisest can make a mistake.’ You are neither wise nor virtuous…” Jill said, raising her sword. “Of course, King Arthur, I do not deny your kingly way. Perhaps your methods are correct, but one cannot be a slave to correctness—”

“So, let’s settle everything here with our swords—” Jill assumed a fighting stance.

“…Hoo…” Artoria raised the invisible sword and aimed it at Gil.

“…Not bad.” Jill grinned.

No one spoke.

But a storm arose, and Gil and Artoria simultaneously pressed down on their feet.

"Bang—Clang!"

The two swords clashed, and Gilles and Artoria collided fiercely.

“King Arthur, you still like to use this little trick to conceal your sword. Anyway, I already know the length of your sword, so how about we do something more fair and square?” Gilles stepped forward, fiercely swung his sword to deflect Artoria’s longsword, and said with a sneer.
