When the girl turned to Kenshin for advice on who to teach first so he could pass the knowledge on, Kenshin suddenly suggested himself.
"What? Don't you have time to demonstrate all these techniques to everyone individually?" Kasumi asked in surprise.
"I can transfer knowledge to each one in a very short time. Roughly the same way I showed you weapons from my world."
"Wow! Can you show me something else? Your world is so cool!" Kasumi whispered with shining eyes, losing all combat mindset. With Kenshin she felt not like a strong kunoichi, but like a little girl craving affection.
"I can, but only if you also show me 'something else'," he whispered slyly in her ear.
"Idiot…" she whispered and blushed a little.
Then Kenshin ordered his sons to return to their usual training and headed with Kasumi to the adjacent room to master the Nara clan's taijutsu himself.
For the next several hours Kenshin tried to attack the evasive girl, but every time ended up on the floor. She herself volunteered to wear chakra suppression cuffs so the training wouldn't turn into a circus.
First of all she showed him extremely tricky elements of deception, evasion, and counterattacks. All these techniques required great flexibility and incredible coordination, which Kenshin had slight problems with. He easily memorized any technique but couldn't immediately repeat it.
Once again meeting the floor, Kenshin groaned heavily and said, "Ugh, that's enough for today, I think."
"I told you an hour ago it was time to rest, but you're so stubborn!" Kasumi said indignantly and helped him up.
"And you're such a gentle girl…" he whispered and tenderly hugged her, kissing her lips.
"Hmph!" Kasumi snorted and turned away. But even so it was noticeable that she had blushed.
"Let's go freshen up." Kenshin said with a smile and, rubbing his sore spots, trudged to the second floor.

The next week flew by almost unnoticed, and every day was like the previous one. In the morning everyone had breakfast, then began intensive training. By the 193rd day there wasn't a single unharmed spot on Kenshin's body, so by the 195th day he finally improved his exo-suit, making it a bit sturdier—now able to easily withstand a fall from the second floor or a half-strength blow from a Genin.
After upgrading the exo-suit, training became more productive. The energy charge lasted exactly two hours of active training and constant beatings from the barely-restrained kunoichi. At the same time Kenshin learned to act at speeds several times higher than without the suit. At first his body refused to readjust to the new rhythm, but by evening he could parry half of Kasumi's weakened strikes and avoid half of her tricky grabs.
On the next day, the 196th, Natsumi and Aya gave birth, giving Kenshin two babies—Thirteenth and Fourteenth respectively. Both had a talent indicator of 21 units, which could not but please the young parents.
That day Kasumi was on pins and needles and took the most active part in delivering her two friends. She knew she would be next—her belly was no longer so flat. When two little bald bundles appeared, the girl couldn't hold back a tremble, imagining that very soon she would give birth to her own babies.
After the birth of two sons, Kenshin received another, twelfth level and allocated the free skill point to the "Talented Offspring" skill, then looked at his "status."

"Wonder how talented a baby from Kasumi will be—she's already a fairly strong Chunin-rank kunoichi…?" he mused, hoping the next son would finally be born with talent above thirty and, realizing his potential, easily become a Jonin.
The next day, the 197th, was the last when Kasumi directly participated in training. Her belly no longer allowed masterful somersaults, so Kenshin arranged a lighter session that day—no jumps or acrobatic tricks.
He had already memorized almost all elements of the Nara clan's taijutsu and mastered the style at 60%. According to Kasumi's estimates, his progress was at the level of a twelve-year-old Genin fresh out of the academy. Kenshin wasn't upset and planned to slowly hone his mastery, focusing not on attack but on avoiding any damage.
In the evening, shortly before dinner, Kenshin invited Twelfth to his office and very quickly awakened his Sharingan. The procedure was surprisingly easy for Kenshin and caused only a mild migraine. He trained his brain every day, and the result didn't take long to appear.
In excellent spirits, he decided to organize his knowledge of the Nara clan's taijutsu in order to later transfer a ready block of information into his sons' heads. The process was quite laborious, so after half an hour of intense work Kenshin felt as if his brain had turned to jelly.
He barely made it to the dining hall, ordered his sons juicy steaks with baked potatoes and a large pot of blue sage tea, and wearily headed to the second floor. After ordering dinner for the girls, he barely staying conscious, went to his room and ordered them not to disturb him until morning.
The girls only stared in shock—they had never seen Kenshin in such a state. They wanted to ask what happened but couldn't resist the order and could only worry.
In the morning Kenshin felt drained and broken. He barely took a shower, dressed in clean clothes, and headed to the kitchen where the girls were waiting anxiously.
"Ah! Kenshin, dear, what's wrong with you?" Aya said worriedly, rushing to him.
The other girls also noticed their husband's painful appearance. Huge bags under his eyes, and his whole face looked as if he hadn't slept for a week.
"Nothing, everything's fine. Just miscalculated my strength. I'll be more careful from now on." he answered and tried to smile.
Thirty minutes of intense brain work under hundredfold focus made themselves felt. Even at the twelfth minute he had felt slight fatigue but paid no attention. In the end those thirty minutes were like fifty hours of work without focus.
"Stop looking at me like that. Let's eat." Kenshin said with a smile and gently stroked the two little ones sitting in high chairs. They watched Father with great interest and laughed merrily when he showed signs of affection.
The girls didn't continue questioning and began breakfast.
