Grandpa Has a Sister

Some say he was a reincarnated demon who possessed strange sorcery, manipulated believers, and intended to wreak havoc on humanity before being suppressed by the righteous Tokugawa Shogunate.

The most widely accepted account is that Amakusa Shirou Tokisada was a handsome young man with extraordinary powers beyond ordinary people, and he was the last person to rebel against the Tokugawa Shogunate.

Because of his resistance, Catholicism lost its foothold on the island nation, and the Warring States period officially came to an end. In order to consolidate his rule, the third Tokugawa Shogunate entered a period of national isolation, with no further interaction with the outside world except for maritime trade with China and the Netherlands in limited ports.

The sorcerer in this body is a drifter from parallel worlds. He has traveled to many worlds, searching for a way, but ultimately could not change the fate of his followers' destruction. So in the end, he gave up and chose to embark on a completely opposite path from his initial one, to make a final 'redemption' for this world.

Like those Heroic Spirit Swordmaster who lost their way in the carnage, their humanity distorted, everything he did was destined to bring about the destruction of humanity and the descent of darkness. Because this event was a predetermined event that had been cut from Human History. No matter how it was changed, no matter what world they lived in, in the Shimabara Rebellion, he and his followers were destined to be suppressed and massacred by Tokugawa's army, with no possibility of salvation.

Yes, there was no hope left in this world. Amakusa Shirou went mad, and in his madness, he heard a call from hell.

Since nothing can save us, we can only seek liberation. This filthy, hopeless world is truly hell, where humanity is left with nothing but suffering.

Therefore, the only way to save humanity is to kill all humans and send them back to the Pure Land.

He will sacrifice this world, then arrive at Chaldea, shattering everything and causing the Human History that Chaldea has repaired to fall apart once again. All worlds and all humanity will cease to exist, returning to the Pure Land and attaining true liberation.

Hidden beneath the darkness, Amakusa Shirou let out a terrifying, sinister laugh. He had become a demon, no longer the saintly boy who could become a holy judge, but a malevolent spirit filled with resentment and regret, ready to destroy everything.

In the near future, the people of this world will witness the moment of destruction. However, most people are currently unaware of this, each preoccupied with their own selfish interests and living their own lives.

As they approached a dilapidated temple by the roadside, they heard a girl's screams coming from behind the temple.

"Shirou! Go! Freeze this snake monster!"

Upon hearing the shout, Shirou turned around abruptly. The voice was very familiar! He quickly ran over and discovered a huge black, demonic snake-like monster behind him, exactly the same one he had encountered in the village that night.

The one fighting the giant snake is a little girl wearing a pink kimono and with silver hair in an exotic style.

She rode a massive polar bear, her mouth agape as she exhaled icy blue breath, freezing most of the snake's upper body and rendering it immobile.

A large sword with a rounded tip appeared out of thin air in the girl's hand, and she slashed at the giant snake with all her might. The polar bear beneath her also swung its giant paw and struck, causing the snake's frozen body to shatter into several pieces.

The snake's head was frozen, preventing it from uttering a single cry of pain, and thus it became a body without its upper body.

"What? Is this all a basilisk monster is capable of?" The girl sheathed her greatsword, kicked the lower half of the basilisk monster on the ground, and curled her lip in boredom.

When the girl turned around, revealing her face, Shirou cried out in surprise.

"I... Illya!!!"

The girl opposite looked at Shirou, scrutinized him for a while, and finally uttered the last name. "Hmm? A human passing by? Eh? You seem familiar? You are... Shirou?"

"Yes, it's me! So you really are Illya?" Shirou asked the girl with a puzzled look.

"Illya? That's the name of the body's owner! So you really are Shirou, the one who knows me!" The little girl jumped up in surprise!

"Awoo?" A huge creature that had been standing beside the girl responded when she called it. It was a snow-white polar bear that shouldn't be there, followed by wolves and rabbits, with an eagle on its back. However, when they noticed Shirou's gaze, they all turned and ran away, then turned into fluorescent light and disappeared.

This does not appear to be an ordinary beast, but rather an animal spirit possessing properties similar to those of Servant.

At this moment, apart from the girl, only a polar bear remained standing there, looking at Shirou with a puzzled expression.

The girl looked at the polar bear and said, "Shirou?"

She glanced again at the man who gave her a familiar and warm feeling, and called out again, "Shirou?"

So Shirou and Shirou looked at each other blankly.

No, it should be Shirou and the Great White Bear staring at each other, completely unable to understand what they had in common.

'Shirou' is the most important name to this girl. Although she lost most of her memories when the god borrowed her body, this name is the only one that frequently appears in her mind. So when the polar bear became her most important companion, the girl named it after this name.

"Um... who exactly are you?"

The girl who looked exactly like Illya introduced herself, "My name is Shitonai now!"

"Shitune? The god of the Ainu people of Hokkaido?" Shirou asked Illya in surprise.

In the Ainu pantheon, all things in nature are considered deities, such as the sun, moon, wind, fire, water, and thunder. These deities have the same appearance as humans in the heavens, but they cannot descend to earth in their true forms. Instead, they possess animals such as bears, eagles, whales, and wolves to communicate with humans, sometimes giving them gifts and helping them escape danger, and sometimes committing evil deeds.

The most well-known deity in the world right now is probably Kanna Kamui, the god of God of Thunder and creation—yes, the cute little dragon who lives with a programmer.

Zhi Du Nei, on the other hand, is a young girl who is a representative hero in mythology, slaying a dragon (or snake).

"Mmm, I'm currently possessed by three deities, which is amazing!" the little girl said proudly, hands on her hips.

"So, you're actually a combination of the three gods residing within Illya's body right now?" Shirou asked.

"Yes, that's how it is," Illya replied with a smile.

The girl's body is primarily governed by the spirit of the Ainu people, who are closest to her, but she also possesses the qualities of two other goddesses. One is Lushi, the witch from the Finnish mythology system, known as the Queen of Boheyura, a villainous character who brings freezing and disease.

Another one is Freya, the more famous goddess of love, beauty, and fertility in Norse mythology.

"So you don't have many memories of Illya?" Shirou asked again.

"Yes, the feeling of wanting to jump up and cheer loudly tells me that I'm so happy to see you here!" The little girl raised her hands and said with a smile.

Shirou thought about it and realized that perhaps not having those memories would actually make her happier. So he stopped bringing up those things.

Shirou spoke up:

"Well, since you're already here, you might as well stay here for now."

"Eh? Is it okay?"

"Of course, since you are Illya, then you are family to me."

When Shirou returned to the village, he found that the villagers were all looking at him with great surprise.

The women pointed at him and whispered among themselves.

"I really didn't expect this. When the young lady returned to the city, I felt sorry for him and even wanted to help him find a good family's daughter. Now..."

"I never expected that after going out, I'd bring back an even younger one! Pah! Men... Hmph."

"Two left, and three more came in... That's why samurai are so different from us farmers."

These words were heard by Shirou, whose ears were several times more sensitive than those of an ordinary person, but he was even more confused and asked in surprise, "What on earth is going on?"

Shirou looked at the men around him and found that they were also grinning and winking at him.

"Not bad at all, as expected of a samurai from the city. Young Shirou is truly blessed with good fortune!"

At this moment, the kind-hearted cattle herder came over, grabbed Shirou's arm, and said, "Don't say anything more, brother, why don't you go home and check on things first?"

"Shirou? What's wrong?" Illya asked.

"No, let's get to my house first," Shirou said.

When Shirou led Illya back to his little hut, they found two guests already inside as soon as they stepped inside.

A samurai girl with cherry-pink hair and a gorgeous purple outfit, and a girl with a side ponytail whose hair color is very similar to his.

"Shirou -kun!" Musashi exclaimed in surprise.

"Shirou-senpai? Is it Shirou-senpai?" Gudako tilted her head and asked.

"Musashi? Gudako!" Shirou looked at the two familiar girls, and now he finally understood why the villagers had been looking at him strangely. It was because he had brought Kiyohime with him that they were mistaken for a couple eloping.

Then the dancer Tamamo-no-Mae came knocking again.

Today, he brought Illya home.

Now Musashi and Gudako have entered this room again.

How can he explain this? How can he possibly explain it? And even if he does explain, who will believe him?

Chapter 369 Grandpa has an older sister

"Hey? Grandpa, do you know Samurai-neechan and Gudako- neechan?" Afeng asked in surprise.

"Senior! How did you become a grandfather?!" Gudako ran up and asked, Musashi also stood up in surprise.

As expected, the savior Alaya spoke of was Gudako. Although she doesn't resemble her at all, she has indeed done such things many times, fighting against Servant, Gods, and the evil of the world to repair the distorted history and save the world.

"Didn't you encounter a blue-clad swordsman carrying a nodachi?" Shirou asked.

"No, who is it? I just arrived in this world. There are no swordsmen here, not even monks on the mountains. I only arrived here a quarter of an hour earlier than you, Shirou." Musashi tilted his head in confusion.

"We did encounter some strange... no, bandits along the way!" Gudako interjected.

"Yes, yes, it's daytime, but bandits have appeared." Afeng nodded.

"Really? Thank you both. Musashi, Gudako, you saved Afeng and Tsuke." Shirou said to the two girls, thinking that it was probably because of the appearance of the savior that the karma of this world began to turn, the rules changed, and the mastermind behind the scenes began the next step of the plan.

"By the way, Afeng, from now on, you're not allowed to go too far away unless an adult is with you. If you want to play, just play near the village," Shirou said.

"Grandpa!" Afeng called out.

"What? There's no room for discussion on this. If you know where the danger is, you shouldn't go any closer. It'll only make people worry," Shirou said, feigning a stern expression.

"I know, but! Grandpa! Grandpa! Did you bring back some kind of animal? A really, really big one?" Afeng asked, spreading his arms wide and gesturing a large circle.

"Hmm? An animal? There is a person, though?" Shirou said with a puzzled look. At this moment, Illya was outside, curiously looking around at the surroundings, as if she was conducting a comprehensive observation of the new Emiya Residence.

However, in the little girl's eyes, Shirou saw a huge, Black Shadow approaching him.

Then Shirou felt something heavy bump against his back.

Shirou turned around and saw that it was Illya's familiar, a creature that was a hybrid of gods and spirits, the Great White Bear that could breathe freezing air. It couldn't stand being alone any longer and revealed itself, nudging Shirou, who had been standing still at the door, with its nose to assert its presence.

Along with Illya, who had also been standing outside the door waiting to be introduced, they stared at her with their large, bright eyes, remaining silent for a long time.

Although nothing was said, it spoke volumes. Seeing the meaning in the Great White Bear's eyes, the bear smiled helplessly and said, "Yes, we can't let you stay outside forever. Come in anyway, but wait here for a bit."

"Awoo?" The Great White Bear tilted its head, but understood Shirou's words and stopped at the doorway.

Illya looked at the Great White Bear, saying, "That's great, Shirou, you can come inside and rest with me now."

As he spoke, Shirou went inside.

"It's a guest." Shirou took a wet towel from inside and went out again.

"Awoo!" The Great White Bear cleverly raised its paws, and after Shirou wiped them clean with a towel, it placed them on the floor inside the door. After doing this four times, the polar bear entered the house.

Fortunately, the houses here were built rather large; otherwise, it's hard to say whether Great White Bear could fit inside.

When the Great White Bear entered the house, Musashi and Gudako, who were sitting inside, stared wide-eyed and cried out in surprise.

"What a huge polar bear!!!"

"It's a polar bear!!!"

But the pink figure that followed Xiong into the house instantly caught their attention.

"Wait! Who is this cute little girl?" Musashi jumped up, his eyes shining brightly as he asked.

"Eh? You're Illya-chan?" Gudako recognized the girl. She had seen this girl before in the special world of magical girl. She and another brown-skinned little devil cosplaying as Emiya were twin sisters.

"Hmm? Your name is Illya-chan! How cute~!" Musashi said with a laugh, her tone slightly flirtatious.

Gudako ran up to the girl, squatted down, pinched her chin with her right hand, and looked her up and down seriously. She said, "This time it's not a magical girl cosplay, but a samurai girl? Is this Emishi- style kimono?"

Shirou held out his hand to block the two of them, saying, "Wait a minute! Even if you like cute girls, at least consider other people's feelings!"

The girl peeked out from behind Shirou, showing no fear whatsoever. She walked forward gracefully and calmly, introducing herself. "Hello, my name is Shitani. Nice to meet you."

"Hello, Shitonai-chan, I'm Musashi. I'm a samurai who travels the world searching for and honing my swordsmanship. You can call me 'Elder Sister' if you like. I was taken care of by Shirou before, and we're practically sworn brothers now," Musashi said with a grin.

"It's just a meal, there's really no need to make such a fuss," Shirou retorted.

Gudako, standing to the side, gave a thumbs-up and said with a hearty laugh, "Hello, Shito-chan~! I'm Elder Sister #2! My relationship with Shirou-senpai is that we share so many things."

"Gudako? Are you sure you're not mistaken?" Shirou asked.

"Like having common companions, common juniors, and things like that," Gudako continued.

"Hmm~, so even in this world, Shirou is still quite popular." The goddess Illya walked into the house with her hands behind her back. Looking around curiously at the furnishings, she spoke slowly.

"Honestly, it's exactly the same as I remember. There are always other girls in the house." My sister's feelings were a bit complicated, but at least there aren't any devilish girls like Rin here, so at least I don't have to worry about Shirou being completely fooled.

"Sister?" the crowd asked, looking at the girl in surprise.

"That's right! I'm actually Shirou's older sister!" Illya said seriously, holding up a finger.

Upon hearing the girl's words, Afeng exclaimed in utter disbelief, "Eh? Shitauchi-neechan, is she Grandpa's sister?"

She already called Shirou, Shirou looked quite young, "Grandpa," and now she'd discovered a girl who didn't look much older than her—was she actually the oldest person there?

"That's right, I am the greatest person here, not just a goddess, but also the master of this place, so show me some respect!" Illya said proudly, hands on her hips and head held high.

"Is that really true, Grandpa?" Afeng's heart was shaken, and she looked at Shirou for help.

"Well... if I had to say, that's not wrong." Shirou nodded and said. In terms of birth age, Illya is indeed a year older than him. Moreover, he was Kiritsugu by Kiritsugu, while Illya was his newborn daughter, so they were undoubtedly family.

However, in his previous life, the Illya he knew was a homunculus created for the Holy Grail War. As a child created by the Lesser Grail, her physical size was also limited to a certain extent and never changed. She lived in a castle in the snow and ice, never came into contact with anyone, and her mental age remained that of a child.
