Kenshin immediately enveloped Aiya in an embrace and kissed her, then pointed to Natsumi and said: "Meet Natsumi—she'll be living with us now."
"Natsumi, meet my wife Aiya and son Ichiro."
"Hi, Natsumi..." Aiya said puzzled, not fully realizing that Kenshin had brought a second woman home. And though she knew Kenshin would eventually bring many women, all of whom would bear him children, facing it in person stirred mixed feelings in her.
"Hello, Natsumi-san." Ichiro greeted, scratching the back of his head.
"Pleased to meet you, Aiya, Ichiro." She said with a smile, holding Kenshin's hand.
"Sorry, but I need to go train..." Ichiro said, turning and heading to the gym adjacent to the living room. The awkward situation embarrassed him, so he decided to leave quickly.
Seeing that Kenshin had taken off his shoes, Natsumi followed suit, then froze in place, not knowing what to do with herself. Noticing this, Kenshin took her hand and led her to the kitchen. Aiya wanted to leave, clearly not in the mood for new introductions, but Kenshin took her hand too, dragging both girls to the kitchen.
After a hearty lunch and an hour-and-a-half heart-to-heart talk, Aiya's attitude toward Natsumi improved slightly. She was appalled at how viciously the mother of the dead teammate had deceived her, and Aiya felt some sympathy for her new "sister."
Learning of the death of Aiya and Kenshin's second son, Natsumi in turn felt pity for the seemingly fragile girl and shared their grief, hugging both at once.
Kenshin didn't want his two women to fight, so he did everything possible to help them find common ground. After an hour and a half of conversation, Kenshin and Natsumi headed to the gym, while Aiya started preparing dinner.
For the next three hours, Kenshin listened alongside Ichiro to a lecture on basic chakra interaction. Almost the entire "lecture" consisted of abstract descriptions that Kenshin, who didn't possess chakra, couldn't comprehend or understand.
He grasped it only superficially, and his main guesses about the physical capabilities of chakra users were confirmed. Natsumi explained in detail the influence of chakra on all body cells, but for Kenshin, it was a dark forest.
The main thing he absorbed was that chakra varies greatly among people, and the chakra quality of a Genin and Chunin is on different levels. Thanks to "chakra quality," a shinobi's body becomes stronger and faster, and performed techniques are more powerful.
He absorbed three main parameters related to chakra:
1 – Chakra Quality. The parameter responsible for physical body strength and technique power. One of the most important parameters for a shinobi's power growth.
2 – Chakra Amount. An important parameter responsible for the amount of chakra a shinobi can expend on techniques. A shinobi with a large amount of chakra can use more powerful techniques and enhance regular ones by infusing extra chakra.
3 – Chakra Control. This parameter governs a shinobi's mastery in manipulating chakra and is one of the key parameters a shinobi must max out to reach Kage level. Chakra control is also necessary for performing the most complex techniques with minimal hand seals. Shinobi with excellent chakra control can perform low- and mid-level techniques with one seal or none at all. Chakra control also slightly improves a shinobi's physical characteristics, allowing chakra to more efficiently infuse muscles and internal organs.
As soon as Kenshin understood and comprehended the three properties related to chakra, he felt a signal from the system and checked Ichiro's status.
Name: Nakayama Ichiro
Age: 20 years
Talent Level: 16
Chakra Quality: 2
Chakra Amount: 3100
Chakra Control: 42%
"Hm, chakra quality 2, amount 3100... Is that a lot or a little?" Kenshin thought, then suddenly decided to check Natsumi's status.
Name: Nakayama Natsumi
Age: 20
Talent Level: 14
Chakra Quality: 3
Chakra Amount: 4200
Chakra Control: 58%
Seeing Natsumi's status, Kenshin was surprised by the completeness of the information—when he checked Aiya's status, he saw only her name and age.
Kenshin was glad he finally had a kunoichi who understood chakra. Starting the next day, Natsumi promised to teach Ichiro seal formation and several fire techniques.
Before leaving the city, Kenshin had stopped by a shinobi goods shop and bought elemental affinity paper. Ichiro's element was fire, like the hot-tempered Natsumi. Kenshin wasn't surprised—his son had awakened the dojutsu of the Uchiha clan, who were always famous for their fire techniques.
After family dinner, Kenshin took Natsumi to the bathroom and explained how the water faucets and shower worked. The girl was thrilled by such technological methods—even in the rich brothel, they heated water the old-fashioned way, with nimble servants bathing the priestesses of love.
Kenshin showered with Natsumi, helping her wash while enjoying the incredible curves of her trained body. The girl was delighted by the reaction she provoked in her man, so she kept bending over, pressing her ass against his big cock.
Kenshin sensibly assessed that now wasn't the best time for sex and just played a little with Natsumi's magnificent body, caressing her breasts, ass, and pussy. In turn, the girl paid special attention to Kenshin's big cock, washing it several times and even kissing it goodbye.
Then the newlyweds dried off, threw on white fluffy robes, slipped on house slippers, and headed to the bedroom.
Learning that Kenshin wanted her to sleep in the same bed with him and Aiya, Natsumi tried to dissuade him and asked him to wait at least a few days until they got used to each other, but Kenshin was adamant. He wasn't going to discuss accepting other women into the family with his wives, so Natsumi silently followed him to the bedroom.
When they entered, Aiya had already changed into her nightie and was lying there holding a book. She glanced at Kenshin and Natsumi, and her eye twitched—she realized they had just showered together. At that moment, she felt a pang of jealousy and offense, thinking she had bored Kenshin and he had decided to find another girl.
Kenshin noticed Aiya's displeased expression, sat on the edge of the bed, stroked her head, and asked: "Aiya, sweetie, what's wrong?"
"Nothing... Except that I'm defective and no longer needed!" Aiya declared, spilling out all the emotions pent up for half a day.
"What nonsense? Of course I need you, and you're not defective—what does that even mean?" Kenshin asked stunned, not understanding what had come over her.
"It means you now have a kunoichi, and you'll make babies with her and forget about me!" she said, tears streaming from her eyes.
"God, of course not! You're not defective at all—you gave birth to my son with Sharingan, remember?" He asked, taking her face in his palms, looking into her tear-glistened blue eyes, and kissing her tender cherry lips.
"Mpfh..." Aiya moaned, enjoying the kiss. She was full of conflicting emotions; the old sorrow hadn't passed, but joy from Kenshin's affection had already ignited in her petite chest.
Kenshin kissed Aiya for another minute, then broke the kiss and looked at Natsumi, who didn't know what to do with herself.
"Come here." He said, and she instantly approached the edge of the bed.
"Since you girls won't befriend each other on your own, you need a push. Natsumi, kiss Aiya." He commanded.
