"Damn it, I don't want to do homework!"
It was night, and in Naruto's home, Naruto was clutching his head and wailing as he looked at the homework with only a few words written.
"Naruto, I will check it tomorrow."
A voice sounded from the window beside Naruto's bed.
"I know! But I...?!"
Naruto first responded helplessly, then realized the voice was increasingly familiar and quickly turned around.
"Sensei, why are you here?!" Naruto quickly stood up and asked Shinji.
Shinji lightly jumped into Naruto's house and said, "I came to see you about something. How much of your homework have you finished?"
Shinji walked to Naruto's desk and looked at it carefully.
Looking at Naruto's expression, Shinji smiled bitterly.
How much does this kid dislike using his brain? With just those few words, he's practically tearing his hair out.
"Alright, I'll guide you after I'm done with this." Shinji closed Naruto's homework book and turned to say.
"Yes, sensei!" Naruto stood at attention, not daring to show any sign of fooling around.
"Mm."
Shinji nodded and walked around, leaving a strange symbol in the places he passed. Naruto just watched, completely unconcerned about what Shinji was doing.
"Done."
After finishing these actions, Shinji clapped his hands. He then slapped the ground, and instantly, the runes he had left in the entire room quickly expanded.
"Wow."
Naruto looked at the runes that seemed to come alive. He had been learning Fuinjutsu with Minato recently, but he couldn't understand them at all.
"The effect is quite good." Shinji nodded with satisfaction.
"Sensei, why can't I understand these runes?" Naruto asked, scratching the back of his head.
"Oh, I rewrote them." Shinji chuckled.
These things came from the rewards that burst from Naruto.
"Sensei is amazing!" Naruto's eyes lit up as he looked at Shinji with great admiration.
Uh—
Shinji, feeling undeserving, rubbed his nose and changed the subject, "Alright, let's get down to business first."
Shinji's fingers moved, and Naruto, seeing the familiar hand signs, knew what he was going to do. He quickly sat down cross-legged.
Shinji chuckled, bringing his index and middle fingers together, and touched Naruto's abdomen.
Buzz—
"Nine-Tails, I'm here to make a deal."
Shinji strolled into the sealed space, a smile on his face as he spoke.
"Damn brat! This is your Sealed Space! How can you just let people in willy-nilly!" Kurama roared at Naruto, who had also entered.
Naruto, however, picked his ear and said with a bewildered expression, "Sensei isn't just 'anyone'."
Kurama: "..."
It glanced at the smiling Shinji, then turned its head and lied down. It couldn't afford to provoke him, but it could ignore him.
Slap—
Shinji threw a scroll into Kurama's cage.
???
Kurama stood up, its fur bristling, looking at the scroll in front of it, then up at Shinji.
"Hey, sensei! Can you bring things into the sealed space?" Naruto broke the silence, asking with curiosity.
"Originally no, but did you forget the runes I wrote outside just now?" Shinji said with a light chuckle.
"Oh?! So that's what they're for?!"
Naruto had an 'of course' expression, not at all thinking how astonishing this matter was.
Minato, who had just appeared, gave a helpless, bitter smile and greeted Shinji.
"Long time no see, Minato." Shinji nodded lightly in greeting.
"Nine-Tails, how about a deal?" Shinji asked again.
Minato stood beside Naruto, not interrupting.
"What kind of deal?" Kurama glanced at the small scroll below, then at Shinji, and finally asked in a muffled voice.
"Inside there's a severed Chakra foot from Eight-Tails. I'll trade it for your assistance in experimenting with some things." Shinji said nonchalantly.
Minato's mouth slightly opened, and he couldn't help but look at that scroll. Knowing about it was one thing, seeing it with his own eyes was another.
"What kind of experiment?"
Kurama was somewhat tempted. The entire Sealed Space was simply too boring. Before, it could chat with Naruto, but now Minato teaches Naruto things every day.
Not to mention Naruto, even it felt its head ache from listening to Minato's lectures.
If it could keep Eight-Tails' Chakra, it would at least have something to relieve its boredom.
"Release some of your Chakra so I can try a new jutsu." Shinji said.
Then, he turned to Minato and asked, "Minato, is that alright?"
Minato quickly waved his hand and said, "You have to ask Nine-Tails about that, I won't interfere."
"Thank you." Shinji nodded in acknowledgment.
"What jutsu?" Kurama glanced at Minato and asked Shinji.
"This…"
Ten or so chains flew out from behind Shinji, continuously surging.
Kurama: ???
Minato: !!!
"Adamantine Sealing Chains!"
At the same time, Kurama and Minato shouted loudly.
"Are you an Uzumaki?" Kurama asked Shinji, its brow furrowed.
Minato also looked inquisitive. The appearance of this jutsu made him feel very nostalgic. After all, this was the technique of Naruto's mother, Kushina.
"No…"
"This jutsu is called Yōshin Sealing Chains, a Fuinjutsu improved by referencing the Adamantine Sealing Chains. It no longer requires Uzumaki blood to use."
Shinji explained to the two humans and one Tailed Beast.
Naruto just scratched his head in confusion. Minato, on the other hand, looked astonished. He had never heard of anyone being able to do this. But Shinji had done it.
Kurama, with a fierce expression, looked at Shinji and said with great disgust, "What? Do you also covet Tailed Beasts?!"
Shinji:" ..."
The look in his eyes, as if looking at an idiot, was unbearable for Kurama, and it couldn't help but roar, "Speak!"
Minato said with an awkward smile, "Uh, Nine-Tails, beneath your feet is the Chakra of one of the Eight-Tails' feet, sealed. My seal, for Shinji, is also easy to enter."
Hearing this, Kurama, which had been full of anger, instantly got beady eyes.
After a long while, Kurama raised its proud head and asked in a booming voice, "How much?"
"Not much, just three times Naruto's Chakra volume." Shinji stated a number.
"Here."
Without hesitation, Kurama released Chakra from its cage, slowly converging in front of Shinji.
"Only this much at a time. Any more, and the seal will go out of control."
After Kurama finished speaking, it looked at the scroll beneath its feet, then up at Shinji.
Shinji looked up and said with a light smile, "I'll unseal it now, but you Tailed Beasts should be able to respond to your main body with Chakra. I hope this can be avoided."
"Don't worry, I am Nine-Tails. Playing with them is like playing with dogs."
