because you'll be dead before you know it! I actually negotiated with my bijū for the chakra exchange. The Kyūbi isn't the type for that. Furthermore, the Kyūbi's chakra is limited, because you took it from the Kyūbi in a tug of war."
Naruto: "...Man, the risk is huge... And despite this, I cannot even use the jinchūriki's supreme technique...?"
Hachibi: "Well, let's just give up on the Bijū Ball... Training your special technique further is a better idea."
Naruto: "Bijū Ball? What kind of technique is that?"
Hachibi: "It's quite simple. You use shape transformation on your own chakra to accumulate it in your mouth and compress it, before firing it."
Hachibi: "It feels just like vomiting"
Naruto: "The let's try it in this mode."
hachibi: "It's impossible if you're not changed into your bijū. Let me explain it first... Turn back B..."
B comes back out. "It's no use... I'm giving up. Nothing left to do but try your special move in your Bijū Chakra mode... Diligently♪"
Naruto: "If I can't use Kage Bunshin, the Rasengan isn't suited for this mode. I have to concentrate on releasing the chakra and rotating and compressing it. I need two pairs of hands for the shape transformation..."
B: "The bijū chakra feels the same as your own hands and feet♪ They're like illusionary versions of your real hands and feet♪"
Naruto: "I see... Like that, hm."
Naruto makes a hand appear behind his back.
B: "That's a nice performance♪ Now have a go at your special technique like this. You're nearing success♪"
Naruto: "Alright!! Rasengan!! Eh?!"
B: "!?" (That's...!!)
The Rasengan unravels and Naruto returns to his normal form.
B: (That technique! It's just like a Bijū Ball! Fool!! Bastard!!)
"Hey, Naruto... That technique. What idiot taught you that?!!"
Naruto: "Eh?! Ehm... Ero-Sennin... Ah, right! Jiraiya-sensei... It was created by the Yondaime Hokage, though!"
B: "...!!" B's shoulder trembles. (The Yondaime Hokage...!! How unexpected... Is this Fate?! A miracle♪)
B: "Rasengan! That's just like performing a Bijū Ball! Commonness♪ A technique invented by referencing to the Bijū's technique! That's what Rasengan is! It's as if the Bijū Ball was entrusted to you!! Lucky♪ It's simple when you're in Bijū form, but in human form, the shape transformation is so difficult, it's nearly impossible. However, there's a way to increase the stability while rotating the chakra!!"
Naruto: "But I didn't even succeed in doing a Rasengan properly..."
B: "Bijū chakra is a combination of plus chakra and minus chakra... a balance! When you compress it, the balance between white and black should be 8:2, before turning it inro a sphere! Try it!"
Towards Naruto's new technique!!
