"Akira Ren…"
Evening.
After dinner.
A blushing Shizune arrived at Akira Ren's room.
She was unusually wearing a white crop top that exposed her midriff and blue-gray denim shorts, paired with black sandals.
Her fair, toned long legs and slender waist that could be be encircled with one hand were on full display. A section of her smooth, flat abdomen was visible, with faint ab lines showing.
Although her curves weren't exaggerated yet, her beautiful features combined with that youthful aura made her look quite captivating.
Akira chuckled inwardly but didn't tease his usually conservative and somewhat thin-skinned senior sister.
He asked, "How's your mastery of Swift Release, Senior Sister?"
"Thanks to you, Akira Ren, I've gradually gotten used to it…"
Thinking about how her strength had skyrocketed several times over in less than a day, Shizune still found it unbelievable.
She smiled and said, "However, my neural reaction speed is still a little behind Swift Release's extreme speed. There's some stiffness, so I need more practice!"
"You can train Lightning Release nature transformation and use electric current to stimulate your cells and neural pathways. That can greatly improve both your speed and neural reaction ability…"
Akira stroked his chin and suggested directly.
"Also, strengthen your sensing ability training!"
Using Lightning Release to stimulate the body and enhance speed and reflexes wasn't a secret.
However, very few people in the ninja world could reach the level of the Third or Fourth Raikage.
Especially for Shizune—a medical ninja who deeply understood the human body and whose chakra control had greatly improved under his guidance—this was not difficult at all.
She might not reach the Fourth Raikage's level right away, but she could quickly improve her neural reactions enough to fully adapt to Swift Release.
At that point, combined with Swift Release, even a Kage-level opponent would find it nearly impossible to gain any advantage over her.
"I understand!"
Shizune listened carefully to Akira Ren's advice.
She knew her junior brother's strength far surpassed hers and was unfathomably deep.
His suggestions were almost certainly reliable.
"Senior Sister Shizune, let's begin!"
Looking at Shizune wearing the bold summer outfit he had bought her—a style completely different from her usual conservative look—Akira smiled.
"Mm…"
Shizune nodded shyly, her face slightly red.
"By the way, besides that area…"
Akira Ren's eyes carried a hint of amusement as he pointed at Shizune's chest, which had already begun to show promising development.
He grinned and said, "Other areas also need comprehensive adjustment. Otherwise, the proportions might not match well…"
"Ah? This…"
Hearing Akira Ren's words, Shizune froze.
Her pretty face instantly turned bright red.
She hadn't thought that far ahead at all and had only wanted to make that one area bigger.
Extremely embarrassed, she stammered, "Then… then I'll be troubling you, Akira Ren!"
This meant she would inevitably have even more intimate contact with him.
But if it was Akira Ren…
She wasn't entirely unwilling.
"Leave it to your junior brother!"
Akira patted his chest proudly.
As a kind-hearted and benevolent healer, he was always duty-bound in such matters.
"Then, let's start with the Yin Seal and Strength of a Hundred Technique training… Spiritualization Technique!"
Soon—
Akira directly activated the Spiritualization Technique.
He entered Shizune's body and took control, demonstrating the Yin Seal and Strength of a Hundred Technique to her again and again.
Afterward, he began demonstrating the Peacock Mystic Technique and taught her the specific training methods and important points to note.
Starting from chakra activation, then to materialization and shaping…
Time passed.
Until 11 o'clock at night.
Shizune's legs were unsteady and weak.
Her face completely flushed, she fled from Akira Ren's room as if escaping.
Looking left and right in the corridor like a guilty thief, afraid of being seen by anyone, she even used her newly acquired Swift Release to rush back to her own room as fast as possible.
Carefully opening the door and seeing that Karin was already asleep, Shizune breathed a sigh of relief.
She quickly grabbed a change of clothes and ran into the bathroom.
"That guy Akira is too bad… how could he do that!"
On the verge of tears, she squatted down and covered her face.
She was so embarrassed she wanted the ground to swallow her up, her face so red it felt like it was steaming.
"It's over… I can never face anyone again…"
...
Meanwhile—
In Akira Ren's room…
After watching Shizune flee in embarrassment,
"Senior Sister is actually… top-tier!"
Akira was momentarily stunned.
He never expected that simply giving her a manual "aesthetic massage" would cause such an intense reaction. The room had nearly flooded…
After spending some time cleaning up the water stains,
Akira Ren's figure turned into an afterimage and vanished.
Swish!
In the adjacent room.
Knowing a certain person's personality well and figuring he definitely wouldn't miss the chance now that he was back,
Tsunade, who hadn't fallen asleep and was tossing and turning somewhat anxiously while waiting,
Suddenly felt herself being embraced from behind.
Her body instinctively stiffened.
But the next moment, she relaxed.
"You little brat, when did you plant a Flying Thunder God mark on me?"
Tsunade glared at Akira, who had suddenly appeared, asking somewhat irritably.
"At first, I thought you had only left the mark on the kunai I gave you earlier."
"But it looks like I won't be able to get rid of you in the future."
"Last time!"
Akira smiled brightly.
Feeling the long-missed soft and warm embrace, he thought to himself that only Senior Sister Tsunade's broad mind could contain his endless ambitions.
"Remember, this is the last time…"
Unconsciously stroking Akira Ren's head and feeling the rascal's attachment to her, Tsunade felt both a bit proud and that her heart had softened.
She warned him.
She had to admit that habit was truly a terrifying thing.
She had found herself strangely missing this brat these past few days.
She couldn't even sleep well.
Now that her human-shaped pillow had returned,
Tonight, she should be able to sleep soundly again.
But this was absolutely, positively the very last time!
"Then I must cherish it properly!"
Akira didn't argue.
He buried his face in her ample bosom and pretended to sleep.
No matter how Tsunade tried to push him away, he clung on tightly and refused to move.
Last time? Yeah, right!
"Don't… don't do that!"
