Another Possibility

Hearing her words, Galan's heart stirred with excitement, as if he had heard some earth-shattering secret.

"[Return Magic]? Does that mean the kind of magic that allows you to travel through time?"

It's not entirely what you think.

Serie shook her head, looking at him helplessly, as if Galan's question was exactly what she expected.

"[Return Magic] is a broad category with many subcategories."

"The 'time-traveling magic' you're talking about, you mean magic that allows your future self to completely immerse themselves in a point in the past, right?"

"But in reality, this situation is governed by the laws governing the world, and it completely transcends the realm of magic."

Her expression was extremely serious, like a teacher giving a lecture, with Galan as her student and the garden Palace as her classroom.

What she just said is the supreme truth of this world, a profound saying from the textbook, and a key point that will definitely be tested on the final exam.

Does this contradict the natural order of the world?

Galan smacked his lips, carefully considering what the other person had just said. Indeed, as Serie had said, if such miraculous magic truly existed, wouldn't the world be in chaos?

Or perhaps it will be like in Steins;Gate, where the user constantly travels between different timelines, each of which is a parallel world independent of the original one.

However, due to the convergence of world lines in the work, this seems unlikely to have a significant impact on the reality occurring in the original world...

No... If someone were to suddenly disappear from the original timeline, it would still have an impact, wouldn't it?

After all, who knows what will happen in a new parallel world after you've lost yourself in that original world?

Serie thought such a thing was completely impossible, but if you really wanted to be serious, wasn't she already an exception since she came into this world?

If even something like this can happen, then his idea of "complete time travel" on the same timeline doesn't seem so absurd anymore.

After all, the most absurd fact is his very existence.

In short, this must all be the choice of Steins;Gate. "So far, the derivative magic of [Return Magic] that I know of has the ability to project a piece of one's own memory into the past." It seems that compared to physical travel, spiritual travel is easier to achieve, perhaps because "magic relies on imagination."

Upon hearing this, Galan looked surprised.

"In other words, is it theoretically possible to achieve this kind of magic simply by imagining 'the future that your past self could have reached if you had known about this event in advance'?"

He never imagined that such magic actually existed, and that his past fantasies had actually come true in this world.

"Hmm, this time it really worked!"

Seemingly pleased that her usually slow-witted student had finally grasped the concept, Serie smiled and said, "But even if everyone understands the principle, almost no one can successfully use the magic spell."

However, she didn't give Galan time to indulge in her fantasies; she quickly poured cold water on his idea.

"Why?"

It seems like something perfectly conceivable, yet it's unusable?

Confused by Serie's inconsistent statements, Galan scratched his head in bewilderment.

Can you imagine how your changes will affect the lives of people other than yourself?

"Apart from me... it seems... it really doesn't work..."

Faced with Serie's questioning, Galan thought about it carefully and found that he really couldn't imagine it.

If one only considered their own future, they could simply tell their past self the lottery numbers that would win them the jackpot, and then cash in the winnings. But what would happen to the person who was originally supposed to draw that winning ticket?

Perhaps he is a desperate person burdened with debt, or perhaps he is a poor person struggling to make ends meet, all hoping that this lottery ticket will turn his life around and change his fate.

But by taking away his opportunity, I also took away his future... Perhaps it's not just his; if he has a family, this will also be a disaster for that family. It might end up with his wife and children separated, his family destroyed, and him choosing to end his life out of despair.

But regardless, even without considering other people, at this point in the deduction, it's almost impossible to achieve this with magic anymore, because even Galan himself can't be sure what kind of ending that lottery ticket will lead to that person's life.

The world never revolves around any one person, and even if magic seems omnipotent and miraculous, there are still places where it cannot reach.

Magic achieved through imagination can never escape the limitations of imagination.

"However... although I believe the veracity of this claim is uncertain, there have been cases like the one you described before."

Seeing Galan frowning, lost in thought, Serie seemed to recall something and suddenly spoke.

"Among the ancient books in the monastery, there is a book called 'Goddess Myth Collection,' which is similar to a fairy tale."

"It recounts the story of a Mage, in both the past and future, simultaneously used Mana to probe a [Goddess's Stone Monument] that had been deciphered by the world, and then transmitted his future consciousness back to the past."

"That sounds incredible..."

"Indeed... if it could really be done to that extent."

As she spoke, she gently touched her chin, looking Galan up and down. Seemingly enlightened by the story, several possibilities raced through Serie's mind, and she felt she was beginning to understand the mystery surrounding Galan...

"What was your situation in this world originally?"

... It might be a little embarrassing to say, but I wasn't even born yet at this point in time.

Galan raised his hands, expressing his helplessness.

The other party seemed somewhat surprised by the answer, but did not ask any further questions.

After hearing his answer, Serie simply lowered her head slightly, lost in thought. It had been many years since anything had aroused her such interest in exploring. Now, faced with this difficult problem, she even felt a competitive desire to uncover the mystery.

Silence fell once again in the main hall, with only the gentle murmur of the fountain beside the flower field audible.

Galan had given up thinking and was quietly waiting for the legendary Mage to give her final judgment. "I have an idea now... Perhaps there is another possibility regarding you."
