Chapter 56 Retirement in Peacetime (5) Kaguya Kirito is training...

While the people of Xilin set off on their journey and the people of Konoha were busy with construction, Kaguya's letter had already been successfully delivered to the [Politics] Honmaru.

"My brother's first letter has arrived!" Itshiki Maru happily shared this good news with the other swordsmen of the citadel. Although they came from different sword schools, had different former masters, and had different experiences, they had formed a brand new family in this citadel.

Kaguya Kirito and Isshiki Maru's relationship is very similar to that of the Genji brothers, so the two get along well, especially Isshiki Maru and Hizamaru, whose rooms are also relatively close.

Upon hearing the good news about Isshiki Maru, the swordsmen gathered around to join in the fun, as reading their colleague's training letters was one of their favorite pastimes.

To my younger brother and everyone in the citadel:

I have been back with my master for some time now, but I have pondered for a long time before writing this letter.

I arrived a little early; the master is only 9 years old, but he and his best friend have already quelled the Third Shinobi World War with lightning speed, officially ushering in an era of peace. Although the two are still young, they are already the undisputed strongest in the shinobi world. I am extremely honored to be able to see these two young yet still powerful figures. I know how wonderful and prosperous the world will be under their protection.

My arrival could not be hidden from them. I confessed my identity and background, and they readily believed and accepted me... I must say, they truly lived up to their reputation. The ease with which the strong handled things.

Seeing my petite and delicate owner from a human perspective for the first time, I couldn't contain my emotions. Little brother, you should understand how I feel.

I'm currently living in the master's house, and my room is right next to the master's bedroom. I'm being trusted, aren't I?

During this time, I learned a great deal about my master's past, too much to write in this letter. I will tell you all about it when I return. I realize that I should focus more on my own self-cultivation so that I can become a sword more worthy of my master.

After learning that I needed to write a letter back, my master asked me if I wanted to take a picture and immediately took action, bringing in my brother, your master, to help me find a way to send the picture over as well. It's hard to imagine that the hatred and war between your two families lasted for hundreds of years.

Brother, we are the symbol of their friendship, and because of them, we have become the representatives of peace, possessing the anecdotes of stabilizing the country, punishing the wicked, and exterminating the invaders.

This concludes the first letter. The photograph was sealed behind the letter by Lord Ogima. I never imagined that the protective seal symbolizing their future bond would be born in this way.

Isshiki Maru turned the letter over. On the back was a logo that was a light white with a slight iridescent hue. The style was familiar to Isshiki Maru—a flaming scythe surrounded by a crescent-shaped philodendron pattern. At the tip of the flaming scythe was an eight-pointed star. The scythe handle filled the gap in the crescent of the philodendron, making them form a perfect round sun.

Isshiki touched the mark, and the chakra belonging to Uchiha Senma within his body was mobilized. He extracted a wisp and injected it into the mark, and the three photos flew out of the sealing array and landed in Isshiki's hand.

The first photo shows Kaguya Kirito, dressed in a dark-colored stand-up collar robe, standing in a vast expanse of kirima grass, holding an adorable little boy with short, dark hair and black cat eyes in his arms. The white katana on the little boy's back is none other than Kaguya Kirito—its current common name should still be Kurokai.

Kaguya Kirito, who always had a calm demeanor like a cloud in the sky, couldn't help but smile and show tenderness in his eyes at this moment. It was clear that Kaguya Kirito's appearance was definitely modeled after his master's appearance when he grew up.

The more a sword's human form resembles its owner, the deeper the influence the owner has on the sword.

“They’re exactly the same!” exclaimed Hizamaru, who was sitting next to Isshikimaru.

Isshiki nodded in agreement, then said, "I look a lot like my master."

"How wonderful~ I want to hug Okita-kun like that too!" As Okita Souji's sword, Yamato no Kami Yasusada, after his polarization, felt relieved but not completely relieved. He had become like Okita Souji, and he couldn't hide his envy when he saw Kaguya Kirito and his master getting along so intimately.

The second photo shows a picture of two young boys. The black-haired boy with cat-eyes is next to a handsome boy with blue eyes. The boy, dressed in dark blue tribal clothing, carries a large fan much taller than himself and a black katana that Zhen Rangjian recognizes. He smiles freely with his beautiful, hazy blue eyes, exuding a wildness like a wild beast. He has one hand affectionately on the cat-eye boy's shoulder and makes a peace sign at the camera with the other.

"It really looks like him." Infected by the atmosphere in the photo, Kishimaru couldn't help but smile.

Upon hearing this, Higekiri came up again and took a closer look, then noticed the key point: "Ah~ that fan, isn't that the 'flame fan' that Dango-maru is jealous of?"

“It’s a flame fan,” Isshiki Maru corrected earnestly. “And my name is Isshiki Maru.”

"Mmm~ A string of pills~" Higekiri smiled.

Isshiki, who values ​​the name his master gave him, Maru: ...

Higekiri: (Smiling) Are you angry?

Knee-maru: (Hands clasped together) Friend! That's how my brother is! Forgive him!

Isshiki - Maru, who is extremely concerned about the name her owner gave her: (Deep breath)

The third photo was probably sent because it was interesting. In it, several people are having a picnic amidst lush flowers and plants. Kaguya's owner is earnestly feeding Kaguya roasted mochi, but it's obvious that Kaguya's mouth is already full of food and she's struggling to chew. She's clearly choking but can't refuse the food, and her lowered face and ears are turning bright red.

This was the first time anyone in the citadel had ever seen Kaguya Kirito so out of control, while the blue-eyed boy next to him slapped his thigh and laughed so hard he almost fell over.

"Haha, it seems that Kaguya Kiritsugu's training is going quite smoothly, very good, very good~" Mikazuki Munechika said with a smile full of emotion.

Kaguya-giri and Isshiki-maru are the only two swords in the citadel whose masters are still alive, but which were borrowed by the [political authorities]. Both blades are not even fifty years old and are incredibly young. Both blades have only one master and their bond with their beloved master is still intact. This alone is enough to make many swords present envious.

"You're here! This must be a letter from Kaguya-sensei, right? How can we celebrate such a wonderful occasion without some delicious treats?" Shokudaikiri Mitsutada said, showing off a freshly baked sweet in one of his hands. "Mitsutada's special—Hagi mochi! Give it a try! Sweets and letters go perfectly together~"

Tsurumaru Kuninaga's eyes lit up, and he raised his gloved hand, which just revealed his index finger and thumb: "Then I'll feed Isshiki Maru-dono!"

These two brothers in the ninja world must be treated equally!

Yi Shi Wan:? ! !

Tsurumaru Kuninaga: Come on~

While the Honmaru was peaceful and harmonious, Kaguya Kirito officially began his training, which took place on the uniquely blessed Mount Kirin.

"Kaguya Kirito, why do you want to train?" Senju Take also asked.

Kaguya paused for a moment, then subconsciously replied, "Because I wanted to see you."

Senju Take was also taken aback, and subconsciously replied, "Thank you."

Kaguya Kiri: "Of course."

Senju Takeya: "Mm."

"Hahahahahahahahahahahahaha!" Uchiha Senma laughed so hard he almost fell over. "You two are so alike! You two shake hands again—Holy crap! You actually did!"

Kaguya Kiri: ... (I just want to hold my master's hand.)

Senju Takeya: ? (Didn't you ask me to shake hands with you, my best friend?)

Uchiha Osaka: No, not at all.

Uchiha slapped away the hand that was clasped together with a blade, saying, "If you're going to train, then train. Why are you holding hands like that? Are you trying to transfer your power?"

Kaguya Kiri: "Tsk."

"So, Kaguya Kirito, do you have a reason to become stronger?" Senju Takeya asked again. "Just like having a legitimate reason for fighting, having a reason will give you the motivation to persevere."

Kaguya Kiri pondered for a moment, then gave an unwavering reply: "To be more worthy of you! To show your might to the enemy! This is the duty I, as your master's blade, must fulfill!"

Senju Takeya: "...Thank you."

Kaguya Kiri: "Of course!"

"Anything else?" Senju Takeya asked again, seemingly quite certain that Kaguya Kirito must have some other answer.

"..." This time, Kaguya Kirito's silence was even longer, but his answer remained firm, "I want to... better protect my younger brother and my comrades." Just as impeccable as you.

Senju Take nodded and went straight to the point: "You possess my chakra, but you cannot actively mobilize and use it. You can only passively trigger its protective mechanism when you are injured."

“Yes.” Kaguya nodded. “Your chakra is gentle and peaceful, like the eternal, silent night in the universe. It does not clash with the spiritual energy system. It has the quality of embracing, accepting, harmonizing, and transforming everything. It is like my blood. It is so natural and harmonious that I cannot even perceive it normally. As you said, it will only be activated to protect me after I have been injured.”

Just as humans cannot perceive the flow of their own blood, but you know that your blood is circulating, Kaguya Kirito has always been very clear that his master has been protecting him from beginning to end, making him fearless of the battlefield and fearless of pain.

In stark contrast to Kaguya Kirito, Isshikimaru's chakra is too violent and yin in nature. It is like flowing, treacherous magma. Although it will not harm Isshikimaru, it can easily cause Isshikimaru's emotions to fluctuate to extremes. Once Isshikimaru's emotions erupt, the chakra belonging to Kirito in his body will also go berserk.

Isshiki Maru usually maintains good self-control, only losing it and erupting when he is injured or facing an unfavorable situation.

“You are my chakra blade, and my chakra is your blood,” Senju Take said. “In the Black World, my power is also your power.”

My strength is also your strength...

Indra, sitting on Senju Takeya's shoulders, seemed to have realized something, and his eyes lit up.

Kaguya Kirito's eyes widened slightly as well. This was the first time Senju Takeya had called him Kurokai. It was the first time he had personally experienced why his name was a curse. The other party had only called out his name, and Kaguya Kirito felt an immense encouragement. His heart and soul were moved and captivated.

Yes, Senju Take wasn't just speaking to Kaguya Kirito, but also to the Black World behind him. With his past self and his future self intertwined in the present, Kaguya Kirito's heartbeat seemed to become twice as fierce, and his master was shining brightly before his eyes.

"Make it truly a part of your body, just like feeling your breath." Senju Take didn't know how to describe the use of chakra. Although he didn't know ninjutsu, the use of chakra was indeed like breathing to him. However, he focused all his chakra use on close combat. "You can breathe unconsciously, or you can consciously deepen your breathing, slow down your breathing, hold your breath, and exhale deeply—breathe, and then strike. That's how you use chakra."

“However, it is indeed too difficult to mobilize Takeya’s chakra. It is too heavy. Each grain of it is like a mountain whose mass has been compressed into the form of dust.” Uchiha Osaka used his eyesight and understanding to analyze Kaguya Kiri in more detail. “You can clearly see the ripples splashing on the surface of the sea, but you can’t know the pebbles that have sunk to the bottom of the deep sea. You have to make your spiritual power become an ocean current, become a tentacle, to touch, perceive, and communicate. Takeya’s chakra will definitely respond to you.”

Spiritual power is the spiritual power generated from the soul. It is a power system with wide applicability and extremely high upper limit. Most importantly, everyone's soul is different, and the aura of spiritual power is naturally different as well. This discernibility makes spiritual power a shortcut that Kaguya Kirito can take. His greatest advantage is that he is the sword of Senju Takeya. He uses his spiritual power to communicate with Senju Takeya's chakra, and Senju Takeya's chakra will definitely respond.

So Kaguya Kiri can do this—

Kaguya Kiri's spiritual power: Master! Lend me your power!

Senju Takeya's chakra: It's you. Here, take it.

If Kaguya Kirito is the most loyal believer, then Senju Takeya is the god who will always answer his prayers. A god who is omnipotent is also a power that belongs to the believer himself. This is Uchiha Osaka's understanding of Senju Takeya's "My power is also your power".

Kaguya Kirito's eyes lit up. "I understand!"

Uchiha Osaka nodded in satisfaction: "I knew it, my best friend's sword is definitely not a fool like Obito's."

Quite by accident, I took a jab at Obito's best friend. Just how hopelessly bad is Obito in your eyes?

Senju Take was also puzzled, but he quickly put the question out of his mind.

"Speaking of which, Takeya, you're really bad at teaching. You're making the child run before he's even learned to walk," Uchiha Senji retorted.

"Really? I know my teaching skills aren't great, but I should at least be able to teach people..." Senju Take said softly.

"Who have you taught?" Uchiha Senji really didn't know who gave Senju Takeya this confidence.

"Indra, I've taught him my Sage Mode, it's so difficult, and he's already learned it." Senju Take was well aware of the difficulty of his Sage Mode, and the fact that he had taught it to Indra gave him some confidence in his teaching abilities.

"That's alright then." Uchiha Senma smiled politely. "Even if the older brother is a stream of consciousness, the younger brother can still achieve enlightenment on his own."

"No! I was able to learn Sage Mode thanks to my elder brother!" Indra kicked his grandson, who was many times older than him, away and said to Senju Takeya with a serious face, "My elder brother is the best teacher in the world!"

“Yes! Master is the best teacher in the world!” Kaguya Kiri blurted out in a brainless voice.

Uchiha Senma lay on the ground, slowly raising his stubborn middle finger. "My dearest friend, on this one point, I absolutely disagree!"

Senju Take also squatted down, looking at his best friend who was clutching his chest where he had been kicked, and asked, "Senma, are you alright?"

"If anything happens, give me a heal—" Uchiha Senji's unyielding middle finger turned into a loyal thumb, "But there's no need for the emergency punch!"

So Senju Take also lowered his fist, and his normal healing was full of his best friend status. Indra crossed his arms, looked at his flexible junior, clicked his tongue, and then arrogantly turned his head and flew to his brother's shoulder to sit down again.

Kaguya asked curiously, "What is First Aid Fist?"

"I'll teach you when you can control my chakra."

"good!"

Author's Note: I've seen everyone's comments! Here's adding two extra chapters in the style of movie reviews! One is a sword-wielding version, and the other is a ninja world version!

[Kaguya Kirito's Letter of Training - Part 1]

To the Judge of Gods:

I returned to his side and decided to stay by his side, convinced that the only way to become stronger was with him.

I was overjoyed that he trusted me and allowed me to stay by his side.

Although I have resolved to train myself to become a sword that can better assist you, I do not want to deceive you. I am deeply attached to and love him. I was born into this world for him. My whole life has been protected and cared for by him. Everything you see of me is because of him. This mark and bond are indelible and deeply rooted in my soul. I am destined not to become a sword that completely belongs to you.

The moment I saw him, I was moved and wanted to stay by his side, even though he had me, who belonged to this part of history, by his side.

Would you be angry, sad, or feel it's not worth it?

I'm sorry, but please wait for me a little longer if you're still willing after reading this letter.
