Naruto: Tenseigan Eye

Here's the revised version with improved flow, consistent tone, and refined humor:

"That's right! Little Heizi lost so easily. I'm optimistic about you, Little Heizi!" Kushina declared proudly, hands on her hips, beaming with satisfaction.

Little Heizi? Well, considering Killer Bee's dark complexion and lean build, she decided the nickname suited him perfectly.

Shinki sighed internally. You two are unbelievable. And now you're his 'Big Sister'? Seriously, Kurama, your Jinchūriki is too much!

Meanwhile, the Eight-Tails felt thoroughly insulted. What do you mean 'lost easily'? Am I that weak?

Kurama coughed lightly, trying to maintain his dignity. "Although Kushina's words are... blunt, Gyoki, you're not young anymore. Why bother arguing with a child? Besides, you're not exactly strong."

The Eight-Tails: "..."

As the "friendly exchange" between the two Jinchūriki wrapped up, Shinki stepped forward. "It seems you two are getting along just fine, so I'm relieved. Kushina, keep 'educating' your little follower. If he calls you Big Sister, you owe me some face, too."

"Hehe, I will!" Kushina laughed, clearly enjoying her newfound authority. She nudged Killer Bee with her foot, who was still sprawled on the ground. "Little Heizi, why are you still lying there? Want me to pull you up?"

"No, no, no! I can get up!" Killer Bee scrambled to his feet, wincing as he stood. He had quickly learned that staying down only invited more punishment.

"Good," Kushina said, satisfied. Tilting her head, she added, "By the way, I heard from Shinki and Minato that you like to sing and rap?"

"Uh… not really, just occasionally," Killer Bee replied cautiously, sensing a trap.

Kushina's eyes narrowed. "I don't care if it's occasional or frequent. While you're in Konoha, focus on your training. No singing, no rapping. If I catch you, you're getting another beating. Got it?"

Killer Bee froze. Even my singing? Seriously?!

Kushina raised her hand and rolled up her sleeves, and Killer Bee quickly stammered, "Got it, Big Sister! No singing! No rapping! Little Heizi and music are officially done with each other!"

"Good," Kushina said with a nod. "I'm optimistic about you, Little Heizi. Get better soon. Once you're stronger, you can decide what songs to sing. For now, focus on recovery. Want me to arrange a treatment package at the hospital?"

Killer Bee blinked, stunned. A treatment package? That sounds ominous.

"No, no! I'll go myself! No need to trouble you, Big Sister!" In his flustered state, he slipped into a rhyme. "I'll be fine, Big Sister—oh no!" He slapped a hand over his mouth, panicking.

Fortunately, Kushina didn't notice. She had already darted off to find Shinki.

"Shinki, look!" she exclaimed proudly, grabbing his hand. "Little Heizi calls me Big Sister now! Isn't that amazing?"

Shinki's mouth twitched. He forced a smile. "Yes, Kushina. You're amazing. Truly incredible."

Unbothered by his halfhearted response, Kushina continued basking in her triumph.

Meanwhile, Killer Bee quietly slipped away, limping toward the hospital to tend to his battered body.

As they walked home, Kushina turned to Kurama, striking up a conversation.

"Big Fox, is the Eight-Tails strong?"

Kurama snorted. "The Eight-Tails? Average at best."

In truth, the Eight-Tails was far from average, but Kurama would never admit it. As the strongest tailed beast, his pride wouldn't allow any acknowledgment of an equal.

Kushina pondered this. "So the Eight-Tails is average, and its Jinchūriki, Little Heizi, is average too. Does that mean together, they're just… an average pair?"

Kurama froze, then slowly nodded. That… actually makes sense.

Kurama puffed out his chest proudly. I am Kurama, the strongest tailed beast! And paired with an Uzumaki like Kushina, I create the strongest Jinchūriki.

Content with this logic, Kurama vowed to share his "average pairing" theory the next time he spoke with the Eight-Tails.

When Killer Bee arrived at the hospital, the staff were taken aback. His bruised and battered appearance was shocking, and some staff instinctively prepared to alert the authorities.

A Cloud Village forehead protector?

If Konoha weren't allied with the Cloud Village, Killer Bee might have been detained on the spot. Thankfully, after verifying his identity, the medical team treated him diligently, ensuring he had no reason to complain about Konoha's hospitality.

As they worked, Killer Bee groaned internally. Eight-Tails! You didn't help me at all!

The Eight-Tails sighed, already tired of the inevitable complaint. "I told you not to provoke her, but you didn't listen. This is on you, Bee."
