Is This What They Call Character Development?

After the bath house's proprietor performed a sliding dogeza and promised to refund her admission fee, Sakura finally let the matter lie. She quickly entered the changing room and removed her clothes, before finally entering the women's section of the baths.

There were naked women everywhere! And yet, Sakura felt nary a tingle in her loins. There were only retired old women taking scalding hot baths this early in the afternoon; everyone else was either at home or at work!

"Damn it, I've lost!" Sakura sobbed. "This isn't fair!"

After having finally reached what she had thought would be nirvana, the women's baths had only turned out to be a hell of her own making. Sakura despondently made her way to an empty spot and sat next to the old lady who had accompanied her here.

Ding! The system has detected the presence of a large number of women!

"Thanks for pointing out the obvious," Sakura sniffled, stifling a sob of despair as she rinsed her body with hot water from the shower head in front of her.

The system highly recommends the use of the Munamori clan's Breast Flow massage technique to absorb as much breast chakra as the host can manage.

"And make my breasts bigger?" Sakura groaned. "And for what? If they'll only get in the way during combat and get me killed, I'd rather stay a washboard, thank you very much!"

And then, it hit her; the system had said breast chakra, not chi. In the Manyuu Hikenchou show, chi was completely useless in combat. It made one's breasts larger, which only burdened a fighter's body and obstructed their movements. Chakra was whole other story, however!

That's not to say Manyuu or Munamori-style techniques were completely useless: the Breast Flow technique was very useful; stealing breasts was highly pleasurable for both parties involved. The feelings it evoked were so intense that it could temporarily incapacitate enemies!

Now that Sakura thought about it, having this technique would make her both a lady-killer and a black widow; she was every woman's natural predator, and she would eventually become so sexy that no man would be capable of resisting her charms. Unless they weren't into boobs.

"System, what exactly do you mean by breast chakra…?" Sakura whispered hopefully.

The Breast Flow technique not only steals breast size for yourself, it also allows the host to permanently seize chakra from female enemies. Additionally, the chakra will remain distinct from the host's natural chakra, meaning that it will conserve its previous owner's properties, such as nature affinities, or any other peculiarities.

That was great and all, but Sakura couldn't exactly go around slashing or massaging her fellow villagers to steal their breast chakra. And what's more, there really weren't many female enemies in the original series. There was Temari, maybe… the Sound Four girl, what's-her-name… Konan, the paper angel… and Otsutsuki Kaguya.

If only Sakura could steal Kaguya's breasts, she would instantly become a six-paths-level being! But that was putting the cart before the horse; how exactly was she supposed to get strong enough to not get immediately annihilated when she finally reached the Rabbit Goddess, without strong female enemies to leech off of along the way?

"Sakura-chan, would you mind washing this old woman's back?" the woman she suspected to be her neighbour called out from next to her.

Sakura lathered the old woman's wrinkly back with soap and started scrubbing. And as she worked, an idea insidiously wormed its way into her skull. Old women didn't need their saggy breasts any more, did they? It's not as if they were still using them, or anything…

"Whoops, my hands slipped," Sakura said monotonously.

Her hands began glowing dimly, and then she 'accidentally' grabbed onto the old woman's breasts. Squeeze. Squeeze.

…

'Just what the hell am I doing!?' Sakura's inner self cried.

…

Sakura let out a low moan, and before her mesmerized eyes, her previously flat chest began trembling, before jumping up to a fuller cup size. They were… jiggling; for the first time in her two lives. She was now the proud owner of perky A-cup breasts! They weren't big, but they were something; which was more than nothing. Amazed, Sakura let go of the old woman and lifted her small breasts with the tips of her fingers.

Chakra Capacity: 0.125KK -> 0.13KK

"My shoulders feel lighter than they have in years," the old woman sighed comfortably. "That felt nice, is that some sort of massage they teach at the academy, Sakura-chan?"

"Er… yeah, that's right!"

"Would you mind if I called a friend of mine over?" the old woman then asked. "Her back's given out, poor dear, but all the best massotherapists are so expensive for us civilians…"

"Er, not at all!"

In the end, the old lady gathered an entire neighborhood's worth of her friends for Sakura to give massages to, so Sakura got to work improving herself. But after a while, she was forced to stop giving Breast Flow massages and swap to the regular kind.

It was completely normal for women's breasts to fluctuate in volume, and generally, the saggy and wrinkly old women wouldn't notice a small reduction in their breast volume, so it was fine to steal a little from each of them. The problem, however, was that Sakura's own chest was shooting up the size charts at a noticeable pace. Even with a towel wrapped around her bust, her breasts were beginning to bulge out of their confines…

And finally, after half an hour…

"That's enough, everyone!" the old lady called out to her friends. "Sakura-chan has a big day tomorrow, so we shouldn't keep her for too long!"

"Ah, would you like me to walk you home?" Sakura quickly offered.

"Why, that's nice of you, dear," said the old lady warmly. "Well, since you're offering…"

Hopefully, this little old lady would really be her neighbour…

The two of them got dressed and left the bath house. As they walked, the old lady wouldn't shut up about her ungrateful son, and when Sakura made the mistake of asking about her grandchildren, she wouldn't stop gushing over how adorable they were…

"Ah, Sakura-chan, there you are!" a man with a strange-looking hairdo called out to her from a window. "And if it isn't Yuhi-san; you're looking as charming as ever!"

"Excuse me, but who are you?" asked Sakura warily.

The weirdo then started bawling uncontrollably.

 "My own daughter refuses to acknowledge me!" he sobbed. "Mebuki-chan, where have I gone wrong!?"

No way!? The weirdo with the purple hair styled like a sakura flower was her father!? Was that where her name came from? Was it still too late to legally change her name?

Another person appeared at the window.

"You're making a scene, husband," a blonde-haired woman told him, smacking him in the back of the head. And then, turning to Sakura, she added, smiling, "Welcome home, dear. How was your day?"
