You think you're worthy of saving the world?

"..."

After a long silence, Rosalia accepted Yuri's explanation.

"But... how did you know that?"

Yuri then explained to her the "someone" he and Celestia had encountered during their adventure.

The black knight, who calls himself "Four Heavenly Kings - Double Phantom Fies", is actually not listed on the Demon King's army's roster.

"So, the guy you met back then, the Double Phantom Fies, was your future self?" Rosalia asked, stroking her chin.

Yuri thought to herself, "As expected of the 'Empress'."

It's easy to explain to a smart woman, saving him a lot of time.

Yuri originally thought it would take at least half an hour to get Rosalia to understand time travel and logical loops.

For time travelers like Yuri, time travel and Loop-themed movies and anime are commonplace themes, but Rosalia has never encountered these things before.

Yuri was both surprised and pleased that she understood immediately.

"So next, you're going to turn back time, go back to the hot spring town a few weeks ago, and have a conversation with your past self... right?"

Yuri nodded: "It was at that time that I first learned of the existence of the Temple of the Mirror from the conversation."

If this "past" isn't filled in... "the present me in the Temple of the Mirror" will cease to exist; perhaps it will be corrected by the law of causality.

After Yuri finished explaining, the two began to examine the hidden mechanisms inside the temple.

They infused magic into every mirror in the prism space.

Soon, new discoveries were made.

"Yuri!"

Rosalia called Yuri to her side.

The mirror in front of the Grand Duchess displayed words after being infused with magic.

The above describes the methods and principles of time travel through the Temple of the Mirror.

Two things in particular are noteworthy—

"The Temple of the Mirror can only perform time manipulations a maximum of 3 times."

"When time travel, one cannot change what has already happened in the past, otherwise the law of causality will correct it."

"and many more……"

Looking at the words appearing in the mirror, Rosalia suddenly thought of something.

"So she noticed after all," Yuri sighed.

Rosalia asked, "Who was the first to find the Temple of the Mirror? And who left these writings for us?"

"The present Yuri" informed "the past Yuri" of the existence of the Temple of the Mirror.

But who exactly discovered this Temple of Mirrors in the first place?

"..."

Yuri paused briefly, then answered truthfully.

"We are probably in a 'second cycle' world right now."

"Second playthrough...?"

Yuri raised his right hand, showing her the note in his hand and the handwriting on it: "The Temple of the Mirror was not discovered, but was built by humans."

The person who built this temple and left us this sarcastic note—

Without a doubt, it's Euryphesse and Rosalia from the "first playthrough," and it's you and me.

"........."

Rosalia's mouth dropped open.

"I suspect that in the first timeline, Celeste still couldn't escape her fate of death."

After her death, the two of us destroyed the lich Leoric, and then spent ten or even several decades searching the world for clues about time travel and resurrection magic...

Ultimately, we built this Mirror Temple, used it to start a "New Game Plus" mode, and added new elements.

The text that appears in the mirror explains how to start a "second playthrough".

Starting a new playthrough will cause some changes to the world's structure.

It was precisely because of the new elements added when starting a new playthrough that Yuri was able to come into contact with the existence of the Mirror Temple from scratch.

“So, what about us in the first timeline…” Rosalia murmured.

“Rosa and I have lived in this world together for decades,” Yuri said with a relaxed expression.

"Well……"

Rosalia bit her lip, but finally couldn't help asking.

"How did you become so sure that the Temple of the Mirror was built by both of us? The handwriting on the note is yours, perhaps only Yuri..."

"Of course, right? If I were alone, I definitely wouldn't have been able to keep going. The most important thing is..."

Yuri looked at her and said, "In the end... in the first timeline, I disappeared because of the correction of causality..."

"Without Rosalia by my side, I certainly wouldn't have had the courage to face the unknown future with equanimity."

“Yuri…”

Rosalia gripped his hand tightly.

Unbeknownst to her, she and her beloved lived and worked together towards the same goal for decades.

Finally, the two of them stood shoulder to shoulder, without any lingering attachment, to welcome their disappearance and look forward to the next cycle of reincarnation.

It's a little... romantic.

"It's a little regrettable that we'll have to use contraceptive magic for decades... After all, if we keep the child, we won't be able to start a second playthrough," Yuri said with a wicked grin.

"Even at a time like this, you're still... idiot!" Rosalia kicked him hard with the tip of her high heel.

Although Yuri's explanation was very reasonable, the Grand Duchess still looked puzzled and uneasy.

"But Yuri... even if you go back in time, history won't change, right?"

"When time travel, one cannot change what has already happened in the past, otherwise the law of causality will correct it."

Rosalia quickly realized the immense limitations of the Mirror Temple through the written description.

In other words, time travel cannot change the past; otherwise, they wouldn't have pinned their hopes on the second playthrough after their first playthrough.

Even if Yuri were to return to the past, he could only disguise himself as a double illusion and tell his past self the riddle-like conversation he had once heard.

He couldn't directly tell Yuri from the past, "Celes will die soon, you must protect her!"

Can't--

All Yuri can do now is repeat what she has experienced: reveal the location of the Mirror Temple to her past self.

Rosalia bit her lip, her pupils trembling: "Celes will still consume a lot of her divinity during her adventures... and then be attacked and killed by Leoric."

Even if we went back in time, we couldn't change anything...

Time will continue to cycle, again and again... Celeste will be murdered, and we will come here...

We're like trapped in an endless loop... we can never escape... Yuri?

At that moment, the Child of Prophecy grasped her hand tightly.

"Will not."

Yuri said firmly, "While we cannot change the past, we can change the future—"

"What do we do?" Rosalia asked incredulously.

The prophesied son said, "The history that we have already come to know cannot be changed, but the history that we have not yet come to know can be changed."

"........."

Rosalia covered her mouth: "You mean?"

"As expected of Your Highness, did you notice?"

Yuri gave a mysterious smile: "If we're forever trapped in the spiral of cause and effect... then all we need to do is break free of that 'loop.'"

After deciding what they needed to do, they officially began their time travel journey.

"The Temple of the Mirror can only perform time manipulations a maximum of 3 times."

In their first playthrough, Yuri and Rosalia had already used the Temple of Mirrors to reset the timeline.

In other words, Yuri has two uses left.

In these two remaining time travels, Yuri will use one of them to lecture her past self.

"Thinking about it carefully, it's really troublesome..." Yuri scratched his head speechlessly.

Rosalia stroked her cheek and said with a smile, "There's no point in complaining now, my knight."

"Well... since even His Highness has entrusted me with this important task, there's no way I can refuse."

So, I set off.

Yuri stood in front of the prism in the very center.

After being infused with a great deal of magic, the mirror rippled like the water of a lake.

“Hey... Rosa, after everything is over…” Yuri began hesitantly.

"what happened?"

“No, it’s nothing after all…” Yuri shook his head.

"It's not impossible for me to agree to your relationship with Celeste."

Rosalia gave the boy a seductive smile as he looked on in surprise: "Let's see how you do."

Yuri felt a warmth in his chest, put on the headless knight's helmet, and stepped into the mirror.

Just seconds later, the prophesied child fell out of the mirror.
