After a tense standoff, the Three-Tails was the first to speak, angrily declaring, "You brat, don't even think about making me your summoning beast. It's never going to happen." Yoruha stood up calmly, looking at the Three-Tails with a faint smile, and said, "If that's the case, if you refuse to become my summoning beast, I'll seal you inside me and become a Jinchuriki."
The Three-Tails sneered, "Seal me? Hahaha, you foolish kid, do you even know sealing techniques? Can your sealing technique really hold me?"
Without wasting words, Yoruha began forming hand seals. In an instant, dozens of black chains flew out from Yoruha's body, each composed of mysterious runes. "Eight Trigrams Sealing Technique!" The dozens of Eight Trigrams seals swiftly spread out, wrapping around the Three-Tails.
The Three-Tails suddenly felt its soul being restrained. The moment those black rune chains touched it, they suppressed the chakra within its body. Its chakra felt as if it had been frozen, completely immobilized.
This was Yoruha's modified Eight Trigrams Sealing Technique, improved based on the Adamantine Sealing Chains and the Eight Trigrams Seal. This sealing technique could be used to capture tailed beasts like the Adamantine Sealing Chains and also to seal them.
Moreover, those black rune chains could even be used in combat. The Three-Tails sensed a threat that touched its very soul. "Damn it, how does this brat have such terrifying sealing techniques?"
"Who exactly is this guy?" The Three-Tails panicked, truly feeling the suppression on its soul from the rune chains. It was clear that this sealing technique could easily seal it.
Yoruha's gaze sharpened as the dozens of rune chains bound the Three-Tails completely. Just as Yoruha was about to drag the Three-Tails into his body, the Three-Tails quickly said, "Alright, alright, I agree to sign a summoning contract with you."
The Three-Tails gave in. Compared to being sealed inside Yoruha, it chose to become Yoruha's summoning beast. After all, as Yoruha's summoning beast, it would still have its freedom, but if sealed inside him, it would be trapped for decades.
Hearing the Three-Tails' words, Yoruha's lips curled into a slight smile, "That's more like it. Being my summoning beast isn't something to be ashamed of, so why resist so much?" Watching the rune chains slowly retract into Yoruha's body, the Three-Tails breathed a sigh of relief. Hearing Yoruha's words, the Three-Tails was speechless.
"I'm a tailed beast, of course, I need to save face." Yoruha chuckled, "You don't need to worry about losing face. Even the Nine-Tails has been a summoning beast before, so what's there to be embarrassed about?" The Three-Tails was stunned.
It didn't know that the Nine-Tails had been a summoning beast. After all, being a summoning beast was quite humiliating for a tailed beast. "Are you serious?"
Yoruha nodded, "I'm a ninja from Konoha, would I lie to you?" Meanwhile, inside Naruto, the Nine-Tails suddenly had a bad feeling, though it didn't know why.
If it knew that Yoruha had spilled its secrets, it would probably want to kill Yoruha. That was the last thing it wanted to be reminded of. The Three-Tails nodded.
At least it found some comfort in that. Although it wasn't sure if it was true, it at least knew that a tailed beast had done it before. And it was the strongest of the nine tailed beasts, the Nine-Tails.
After retracting the chains of text, the Three-Tails said, "Remove this water serpent, or how else can I sign a contract with you?" Yoruha wasn't worried about the Three-Tails escaping. So, with just a wave of his hand, the water dragon that had been coiling around the Three-Tails instantly dissipated.
As the massive body, hundreds of meters long, vanished, a torrent of water crashed onto the lake's surface, sending waves dozens of meters high. However, Yoruha didn't mind. The Three-Tails, looking at the water dragon that had turned into a mere puddle, felt a bit dazed.
"What kind of ninjutsu is this? Ordinary Water Release techniques can't achieve such an effect," the Three-Tails remarked, eyeing Yoruha.
Yoruha replied calmly, "It's just a regular Water Dragon Bullet Technique." "Alright, let's sign." Yoruha had learned the Summoning Technique.
Thus, he knew well how to sign a contract with a summoning beast. Although the Three-Tails was somewhat reluctant, it had no other choice in this situation. Moreover, it felt that becoming Yoruha's summoning beast was a relatively good option.
It was well aware that it wouldn't be long before a ninja discovered it. Once discovered, it knew from past experience what the ninjas from various villages would do. Rather than being sealed inside a jinchūriki for a long time, it would rather be Yoruha's summoning beast.
At least most of the time, it would be free. The most crucial factor was Yoruha's formidable strength. The Three-Tails believed Yoruha had the power to fulfill his promise and truly protect it from being sealed.
After signing the summoning contract with Yoruha, Yoruha smiled, "Finally, I've filled the last gap." Seeing Yoruha's cheerful smile, the Three-Tails was somewhat speechless, "I feel like you don't even need a summoning beast, given your strength."
Yoruha replied nonchalantly, "I don't think so. Different battles have different needs." "Besides, if in a fight, other ninjas summon their beasts, even if I can handle the battle on my own, it feels like I'm a notch below them." The Three-Tails was exasperated, "Don't tell me that's your real reason?"
Yoruha didn't answer but instead said, "Alright, I have a mission to complete, so I'll take my leave." As soon as Yoruha finished speaking, he disappeared from the Three-Tails' back. The Three-Tails was left stunned.
"What on earth is with this guy?" "Aren't we going to get to know each other?" "How are we supposed to cooperate in battle if we're so unfamiliar?"
The Three-Tails was quite speechless. However, it didn't have much of a grudge against Yoruha. Especially now that Yoruha had signed a summoning contract with it.
It just felt that Yoruha was somewhat unreliable. "Luckily, your strength is sufficient; otherwise, in future joint battles, you'd definitely get me killed," the Three-Tails grumbled.
Yoruha's strength had indeed earned its approval. No matter how you looked at it, Yoruha had subdued it with just two Water Release techniques, which reassured the Three-Tails. Moreover, by becoming Yoruha's summoning beast, it existed as Yoruha's comrade rather than being an energy source for a jinchūriki.
Always sealed in a dark and uncomfortable environment. Most importantly, it could sense that Yoruha was different from others; Yoruha truly had no intention of exploiting it. Perhaps, as Yoruha said, he merely wanted a summoning beast that looked cool when summoned.
Thinking of this, the Three-Tails didn't know what to say. "This guy, who knows what it'll be like being his summoning beast?" Shaking its head, the Three-Tails slowly sank to the lake's bottom.
The Three-Tails knew well that with Yoruha's strength, he wouldn't summon it often in future battles. It even thought Yoruha might not summon it once a year. It believed this because Yoruha's strength was simply too overwhelming.
In the Three-Tails' view, he didn't need to summon it for assistance. If Yoruha couldn't handle an enemy, it wouldn't be able to either. This was something the Three-Tails understood clearly after the recent battle.
"Damn it, the more I think about it, the more it seems like that guy just sees me as a tool to show off." The more the Three-Tails thought about it, the more annoyed it became. Of course, it didn't harbor any hatred towards Yoruha.
It was just a bit displeased at being used as a tool for showing off.
