[310] World Destruction Crisis

"It's New Year again."

Kazuya looked at the sky and said, "But, surprisingly, it's not snowing."

"Yeah." Shiki, who was beside him, also looked up. "Without snow, there's no New Year atmosphere... Oh, here it comes."

"Huh?"

Kazuya was momentarily puzzled, and indeed, snowflakes began to fall from the sky. "Haha, that's better."

"By the way, any New Year gifts?" Shiki asked with a smile. "At this time, you can't just not give anything, right?"

"Yeah, prepared one." Kazuya smiled and took out a box that had been prepared beforehand. "Here, New Year's gift."

"Alright, I'll open it without hesitation."

"How about waiting until we get home?"

"Well, since it's your gift, I want to see what it is." Shiki lowered her head without looking at Kazuya, opened the box, and revealed the delicate dagger inside.

"A dagger?" Shiki's eyes lit up. "You finally decided to give me something like this."

"Yeah." Kazuya nodded. "No matter what, we will face parallel worlds next. Although I will try my best to protect you, accidents may happen unexpectedly. So, you also need to be able to protect yourself."

Shiki swung the dagger playfully a few times, then stabbed towards Kazuya—

But as she got closer, she stopped. "What's this? You, not even dodging."

"Haha, you won't really strike, after all, you've always been like this." Kazuya laughed and said, "I commissioned a puppeteer named Touko Aozaki to make that dagger. It has good ripple conductivity, and the blade has some characteristics that cannot be healed. Of course, it can release up to the level of a Noble Phantasm, so it can undo it. This way, it can prevent you from accidentally injuring yourself, right?"

"There won't be such accidents!" Shiki turned her head slightly, looking at the dagger in her hand, smiling, and put it away. "But, um... I'm satisfied with this gift, and, um, thank you. Thank you."

Shiki put away the dagger and changed the topic, saying, "What about your sister? After all, it's New Year..."

"No, she's still in 2012. It's still a few months until New Year... maybe when we celebrate the New Year in 1994, she'll reach 2013. Of course, I didn't bring her over."

Kazuya held one of Shiki's hands, and the two of them walked forward slowly. "Well, she has grown up after all. She left me for two years before. She has changed a lot..."

"What's wrong?" Shiki looked at Kazuya with confusion. "Although you say that, your expression doesn't seem like that."

"Well... there's still a long time to worry about. It's just that I feel her world is a bit dangerous." Kazuya sighed and talked about the recent situation.

A while ago.

Kazumi participated in a test organized by an organization called "Chaldea."

Qualified as a "Master."

At that moment, Kazuya knew how her world had changed.

In the Holy Grail War in Fuyuki City, the Lord of the Clock Tower, Marisbury Animusphere, for the final victory of the Holy Grail War, used funds to establish Chaldea.

Relying on the relationship with Kazumi and as a relative of the "Master," he also applied to visit Chaldea. However... it hasn't been approved yet, although it's been some time in this world.

On the other hand, it has only been a few days in Kazumis world.

Even so, it is almost certain that her world is the world of Fate/Grand Order.

That's why it feels a bit annoying. She had already told her about the potential world destruction crisis in that world and wanted to take her away, but it failed. She simply didn't want to leave.

She even replied, saying, "In that case, I can't leave even more. Since if this world is going to be destroyed, I'll just save this world."

Tsk, she really has confidence in herself!

"It's all the same."

"Hmm? What's wrong?" Kazuya asked with some confusion.

"I said you siblings are completely the same, aren't you afraid of death at all? Or rather, you don't even consider your own death." Shiki sighed slightly. "Even though she said that, in the end, you also tacitly agreed and didn't forcibly bring her back or anything."

"Well... after all, world destruction crisis are quite common, and... her world still has several years. Putting it on our side gives us even more time, which is sufficient, this time..." Kazuya said with a slight smile.

However...

What he cared most about was not this.

Fate/Grand Order.

The entity named Goetia burning human history is not the first time... Kazuya had experienced such a situation in several parallel worlds he crossed with D4C in search of opportunities.

But he was still too weak now, although he could defend himself, participating in such a battlefield was still far beyond his reach.

The turning point was in Solomon, and person named "Lev."

Lev committed suicide, and if he didn't, the burning of human history wouldn't happen.

Lev didn't commit suicide, and then the burning of human history would activate.

However...

In all these worlds, defeating Goetia meant the end. No information about something called "Lostbelt" was obtained.

So... he had a conjecture.

Is there such a world where, regardless of whether Lev committed suicide or not, Goetia would still burn human history?

Because... after that, the world would face an even greater crisis —

He hoped... that Kazumi's world wouldn't happen to hit this jackpot.

In his view, celestial body that will come to his world in 2030 was more dangerous than the burning of human history.

However —

Whether it was the burning of human history or the celestial body, both might be less dangerous than what appeared in FGO 2.0 before he crossed over.

But when he crossed over, there was only a prologue about 2.0. The summoning system he drew from also had no information in this regard.

So...

It was completely unknown.

However...

As long as he was strong enough.

The unknown also meant it was interesting.

"Well, that's probably the situation with the crisis." Kazuya revealed some of the things he knew.

He didn't intend to hide too much from Shiki.

"Well... it sounds interesting, huh? Hey, how about counting me in when saving the world and such? If it's that kind of battle, there must be people worth killing, right?"

"No, such people don't exist. Give up."

"Hey! You, this guy—"
