I, the System Creator

As for Miyu's surname, Chu Chen had agonized over it for a long time. Calling her Chu Miyu just sounded rather strange.

But if he called her Miyu Emiya again, Miyu herself would probably disagree. Besides, Miyu had never once mentioned the name Emiya in front of him. If he brought up that surname, Miyu would likely grow suspicious of him, and the trust they had built between them might collapse because of that tiny seed of doubt.

So Chu Chen simply asked Miyu what surname she wanted, and Miyu said:

"Of course I'll take Mr. Chu Chen's surname..." Miyu sounded a little bashful as she said it.

Well, maybe Chu Chen's eyes were playing tricks on him. Otherwise, why would he think Miyu had suddenly become bashful?

If he weren't afraid of getting arrested and receiving the standard minimum sentence of three years up to the death penalty, Chu Chen would have asked outright.

Are you planning to marry into the family? Otherwise, why would you take my surname...?

It suddenly felt as though Miyu's role at that moment had become either his wife or his daughter...

So, when Miyu was completing her enrollment paperwork, Chu Chen silently wrote down Chu Miyu.

It did sound a little strange, but he would get used to it... He would get used to it...

After completing the enrollment procedures, Chu Chen handed Miyu over to the teacher in charge of Illya's class, Fujimura Taiga.

That was right—the legendary Tiger of Fuyuki...

After Fujimura Taiga patted her chest and led Miyu away, Chu Chen finally breathed a sigh of relief.

His great system-creation enterprise could continue. If he did not have work to do, Chu Chen would definitely devote every second of the day to the glorious cause of making systems.

System Completion: 10%

Note: Once the host assigns a cumulative total of 5 tasks to each system host, a System Completion Critical Hit can be achieved!

Note: Tasks assigned by the host must affect the Worldline of at least one host world!

Seeing the notes below, Chu Chen could not help raising an eyebrow. More and more, he felt that this was not an ability, but a system for creating systems. Otherwise, why would there be notes and such? Was this supposed to be a joke...

But changing a Worldline? How was he supposed to pull that off? Illya's world aside, with him, this butterfly, here, a single flap of his wings might send the Worldline veering into some ravine.

Yukino's world... Honestly, not long after he gave her a system, that world had completely gone off the rails. The teacher who was originally supposed to join the Service Club had vanished to who-knew-where. Chu Chen had not deliberately asked about it; he had merely learned through casual conversation that her world's Worldline had already veered off into some unknown ravine.

Busujima Saeko's world... The virus had not started spreading yet. Was he supposed to give her a task to save the world?

Ai's world... Would it count if he made Ai become a legendary heroine and beat the Black Organization to a pulp?

"This task is kind of a headache... The result caused by the task itself has to affect the Worldline... Hmm! I've got it!"

A wickedly mischievous expression immediately appeared on Chu Chen's face.

Haibara Ai triggered Event Check-in: Let Mouri Ran learn the true identities of Edogawa Conan and herself.

Task Restrictions: Direct explanation is prohibited! Edogawa Conan must not learn that she exposed the truth! Mouri Ran must not be talked out of it by Edogawa Conan afterward! Mouri Ran must be completely convinced of this matter! Mouri Ran must not reveal it to anyone else! Violating any one of the above restrictions will result in task failure!

Check-in Time Limit: 48 hours

Check-in Reward: 1 Holy Grail wish opportunity

Reward Description: The scope of wishes is very limited. A wish to revive someone can be granted, but it may be fulfilled in another manner. A wish to destroy an organization can likewise be granted, but due to the world's own level of power, high-risk weapons may go out of control and directly nuke the area where the organization's members are located...

Seeing that reward, even Chu Chen's mouth twitched hard. That flaw was genuinely terrifying.

What if one of the organization's members was near Ai? If it decided to nuke the place, Ai herself would be gone too.

You made that high-risk weapon sound so mysterious, but then you added the words "nuke the area." Could anyone possibly not know what it was?

And the restrictions were pretty harsh too. Still... This task's reward was unusually powerful...

Since the system believed this task was worthy of such a reward, did that mean... that in the system's view, Mouri Ran was the type who was extremely easy for that Shinigami Elementary School Student to fool?

Haibara Ai: "!!!"

Illya: "!!!"

Yukino Yukinoshita: "!!!"

Busujima Saeko: "!!!"

Miyu: "...!!!"

Administrator: "Can you all say something? What kind of reaction is it to just send exclamation marks!"

Haibara Ai: "As long as I get this reward... my sister can be revived, right?!"

A deeply excited look instantly appeared on Ai's face. She had finally encountered a reward that could revive her sister.

Busujima Saeko: "Theoretically, she should be able to come back to life... But that flaw really is worrying!"

Yukino Yukinoshita: "Exactly. The reward description says it can be fulfilled, but it may happen in another manner. Who knows what bizarre method that 'other manner' might be..."

Haibara Ai: "This... shouldn't be too serious of a problem, right..."

Ai's tone was extremely hesitant. As long as her sister could be revived, the method should not matter.

Administrator: "Is that so?"

Chu Chen raised an eyebrow slightly, and an ill-intentioned smile appeared on his lips.

Haibara Ai: "What are you trying to say, Administrator...?"

Administrator: "For example, your sister really is revived, but she stays before you in the form of a soul?"

Haibara Ai: "...!!!"

Administrator: "For example, your sister really is revived, but she stays before you as a zombie?"

Haibara Ai: "...!!!"

Administrator: "For example, your sister really is revived, but she suddenly changes from a woman into a man?"

Haibara Ai: "...!!!"

Ai's expression changed again and again. After that demon-like Administrator put it that way, she no longer dared to use that Holy Grail wish. No matter how she looked at it now, the Holy Grail wish seemed incredibly unreliable.

Yukino Yukinoshita: "Administrator, are you a demon?"

Just Treat It as Your World Undergoing a Tribulation...

Illya: "Sister Ai... Are you still going to use that Holy Grail wish opportunity?"

Illya looked at the chat above with cold sweat running down her face, feeling rather speechless herself.

The Administrator really knew how to scare people. But after thinking it over carefully, if it said resurrection might happen in another manner, it really could turn out like that. Honestly, after hearing that, even she would not dare use it casually.

Ai's mouth twitched hard as she warily glanced at the Holy Grail wish reward, exhaustion filling her heart.

She had finally come across a reward that could revive her sister, only for the Administrator to say something like that...

How could she dare use it recklessly now? She would finish the task first, then decide whether to use it.

Haibara Ai: "I've decided to complete this task first. After all, I haven't even received the reward yet..."

Yukino Yukinoshita: "That's true... But Ai's luck is genuinely amazing. How wonderful would it be if I had a task that good... Well, I'm just jealous. Luck like that will never fall on my head."

Busujima Saeko: "Jealous +1..."

Miyu: "... Jealous +1..."

Illya: "Jealous +10086..."

Haibara Ai: "Illya, your check-ins are basically much better than ours. If you're still jealous, are you even letting us live...? You should know that system check-in rewards are very likely to be things from one's own world..."

Illya: "Hehe... I guess that's true! Rin and Ruby both said the magical energy inside me was absurdly huge. Yesterday, they kept asking whether I was descended from some Magical Noble Family. When Ruby and Rin found out I came from an ordinary family, the looks on their faces were so funny! I even forgot to take a screenshot..."

Illya could not help scratching her head with a foolish grin. Back when she knew nothing about magecraft, things like endless Magic Power +1 had been useless to her. But now that she had a wand, she could utterly dominate the battlefield.

Even after Rin discovered that she had been knocked unconscious in a single move, she silently accepted Illya as Ruby's new owner. There was no helping it—Illya's power had truly exceeded Tohsaka Rin's expectations.

This little girl was a wild genius...

Haibara Ai: "Illya, your personality is pretty awful too..."

Ai was speechless as well. She seriously suspected that the adorable Illya had been led astray by someone.

Illya: "Oh, right! Miyu, that transfer student is you, right...?"

Miyu: "... Yes!"

After hesitating for a moment, Miyu quietly replied, then glanced at a certain silver-haired, red-eyed girl.

The reason Miyu had been able to identify Illya at once was because she had discovered that her system could lock onto Illya's system. In other words, could systems created by the same person locate one another? Or did they only lock on when they were close?

Yukino Yukinoshita: "Miyu still doesn't like interacting with us... Ai, as a veteran in this area, do you have anything to say? Maybe you could help Miyu become much more cheerful..."

Haibara Ai: "I'm not a veteran in this area! My personality is still very different from Miyu's!"

Ai felt like tearing her hair out. She was not bad at talking; she was merely cautious!

Chu Chen continued improving the system's completion while scanning the conversation within the System Network.

Raising an eyebrow slightly, Chu Chen was inclined to let Illya and Miyu interact further.

Right, if he let Illyasviel von Einzbern appear early, would that count as causing a change in this Worldline?

But how could he separate Illyasviel von Einzbern? This was a very serious question. The first time Illya turned into Illyasviel von Einzbern, the seal had loosened under pressure during a crisis. The second time, an error occurred while dealing with the leylines, causing magical energy to flow backward. Illya used the Archer Class Card again, and the seal was directly opened.

In other words, perhaps some external force could separate Illyasviel von Einzbern from Illya?

Chu Chen instantly fell into a dilemma again. This System Completion Critical Hit task required him to issue tasks himself. Once he personally interfered, it would no longer count. That was what left Chu Chen most helpless.

Busujima Saeko: "@Administrator, may I ask if you're there? Creatures called zombies have inexplicably appeared in our world. Do you know what's going on?"

Though Saeko spoke of a crisis, her tone remained as calm as ever.

There was no helping it. To her, these mindless zombies were nothing more than a single slash each. They had not yet become enough of a threat to endanger her.

While reveling in the excitement of slaughter, she had not forgotten to ask the Administrator about her world.

Chu Chen was immediately jolted from his thoughts. After taking a glance, he pursed his lips.

Had the main storyline over there finally begun?

Administrator: "Just treat it as your world undergoing a tribulation..."

Haibara Ai: "A tribulation, my ass... So Saeko's world is actually a Resident Evil world? Administrator, you knew and still didn't say anything sooner. Maybe we could have solved this before it happened..."

Administrator: "Saeko doesn't know which suicidal idiots will cause Resident Evil, and I'm only responsible for management, not spoilers. Otherwise, I wouldn't be called an Administrator—I'd be called a Spoilerator!"

Haibara Ai: "..."

Illya: "..."

Yukino Yukinoshita: "..."

What you said made so much sense that they had no response...
