In Honkai Impact 3rd, the younger sister is actually a Taimanin

In recent years, there have been many Taimanin families that completely disappeared due to the severance of their bloodlines.

Rin Uehara had also heard that the Mizuki family had few members, and even Mizuki Yukikaze seemed to have been born by Mizuki Shiranui using some artificial means.

The appearance of Mizuki Yu at this time aroused Uehara Rin's curiosity.

The one who could be given the surname Mizushiro was either a child secretly born to Mizushiro Shiranui before Yukikaze, or a son-in-law adopted from a side branch of the Mizushiro family or directly adopted.

In this country, when there is no suitable heir, it is completely reasonable to recruit a son-in-law to become the family heir.

In Uehara Rin's eyes, Mizuki Yuu should be the child husband chosen by Mizuki Shiranui for Yukikaze, and it seems that he is very likely an heir with outstanding talents carefully selected from the branch family of the Mizuki family!

"Asha-ji really agreed to let this boy become a Taimanin?"

"Why do I feel that this boy seems to have a power that is completely different from the Anti-Demon Factor?"

Rin Uehara looked carefully at Mizuki Yu in front of her, and soon she discovered that the chakra in Mizuki Yu's body was completely different from the anti-demon factor.

"Although Lady Asaki agreed to let Yu-kun join the Taima Ninja, Yu-kun is not a Taima Ninja."

"Yu-kun, this is Asha-sama's friend, and should also be considered Yukikaze's teacher, Rin Uehara."

"This is Mizuki Yuu, who was accepted by Senior Shiranui..."

When Yazu Shiraz was introducing Mizuki Yuu and Uehara Rin to each other, she was about to explain Mizuki Yuu's identity and tell Uehara Rin that Mizuki Yuu was rescued and taken in by Mizuki Shiranui when he was a child and was Yukikaze's non-blood-related brother, but Uehara Rin interrupted Yazu Shiraz with an expression as if she had expected this.

"The child son-in-law brought home by Shiranui-san is also the future head of the Mizuki family, right?"

As Uehara Rin finished his words, everyone present fell silent at the same time.

Yazu Yukikaze and Yukikaze didn't actually have any wild thoughts at first, but after hearing what Uehara Rin said, they couldn't help but doubt the real purpose of Mizuki Shiranui bringing Mizuki Yuu home.

If we must say that Mizuki Yu is regarded as a child husband prepared for Xuefeng, it does not seem unreasonable!

"Watch~!"

Thinking of this, Mizuki Yukikaze and Yazushiro couldn't help but look at Mizuki Yu who was standing beside them.

Especially Xuefeng, thinking that her own onii-chan might become her future husband, an indescribable feeling of shyness came over her.

Xuefeng herself has a vague affection between men and women for her own Onii-chan, but she has never expressed her feelings.

If Oni-chan is really the child husband that I, your mother, have prepared for her, Xuefeng feels that she can still accept it. After all, this is all arranged by her mother. How can she refute it?

"Xuefeng and Miss Zi, can you please stop looking at me with those weird eyes?"

"I have never heard of child-raising husbands before. Aunt Shiranui probably won't interfere with me too much in this matter."

Mizuki Yu rolled his eyes and couldn't help but say.

Xuefeng has a vague feeling for him, but Mizuki You is not the kind of fool who knows nothing about feelings and is slow to react.

He could more or less sense some clues, but Mizushiro You had not yet figured out how to respond.

Mizuki Yuu is very self-aware and knows that he is not a particularly loyal person.

After finally traveling through time, he still found himself in such a somewhat broken two-dimensional world. He had already had a bottom line by not completely letting himself go and spreading the breath of hormones and the seeds of life to those beautiful, plump, beautiful big sisters and young and beautiful girls around him.

Of course, he also has a good impression of Yukikaze, his sister who grew up with him and has no blood relationship with him. But besides Yukikaze, he also has a good impression of Akiyama Rinko, Yazushiro, Asahime, Aunt Shiranui, and even Uehara Rin, whom he just met today.

Mizushiro You admitted that he was just lusting after the bodies of these beautiful older sisters. Any boy with normal physical development and no sexual orientation would probably lust after the bodies of these beautiful older sisters with good figures.

In this situation, it is certainly impossible for Mizuki Yu to take the initiative to confess his feelings to someone of the opposite sex.

"In this era, there are no such things as child husbands and child brides. Aunt Shiranui is still very open-minded. She will encourage me to fall in love freely!"

"Huh~~ I never thought of asking Onii-chan to be my child husband. Just thinking about that kind of thing makes me feel weird!"

"Luckily, mom didn't have such plans, otherwise I would have to think about how to refuse!"

When Shuicheng Xuefeng heard Shuicheng You directly deny Tong Yangfu's statement, a trace of barely perceptible loss flashed in his eyes, but soon disappeared.

Pretending to be indifferent, he snorted coldly and said to Mizujo Yu.

Although Xuefeng acted like this and didn't care, as Mizuki Yu, who had lived with Xuefeng day and night and under the same roof for ten years, he knew his sister's tsundere personality very well.

From the expression on Xuefeng's face, the look in his eyes, and the tone of his voice just now, he could feel that Xuefeng must be a little angry.

Fortunately, he already knew how to comfort his sister when she was angry, so he didn't have to worry too much about this matter.

"Young man... I'll just call you Yu-kun. Even though you're not a Taimanin, I'm curious about the new power you've mastered!"

"Would you like to spar with me? I really want to see your strength."

Rin Uehara did not dwell too much on the matter of 'child-raising husband'. Instead, she looked at Mizuki Yuu in front of her with great interest and took the initiative to invite him to a competition.

Although the power of the Taimanin comes from blood inheritance, for some unknown reason, most of those who can awaken the power of the Taimanin factor are women, so there are very few men to be found in the Taimanin organization, and powerful men are even rarer.

Although Mizuki Yuu cannot be considered a Taimanin, he still caught the attention of Uehara Rin.

Although the Uehara family does not have a legitimate heir like the Mizushiro family, Mizushiro Yukikaze, the Kotonoha family is definitely not very prosperous.

If Rin Uehara were her age in the past, she would have been urged to get married and have children. Although no one is urging her to get married now, perhaps because of her age, she can't help but have similar thoughts.

But it is not so easy for her to find a suitable candidate. After all, Rin Uehara doesn't want to just settle for an ordinary person.

Although Mizuki You is a few years younger than her, his appearance, temperament and ability meet her standards for a partner.

As for age, unless something unexpected happens, Taimanin usually has a longer lifespan than ordinary people, so the age difference of less than ten years is not a big deal!

Chapter 18: Infiltrating the underground black market?

At the training ground of the Taimanin Tokyo Headquarters, Mizuki Yu noticed that Uehara Rin was eager to try, but he did not agree to her request to compete with her.

It’s not because Mizuki Yu was worried that his strength was weaker than Uehara Rin and he would lose to the opponent, but he was just thinking about going to the special space next to the training ground, which was said to be formed by overlapping and merging with the demon world space, to hunt monsters and perhaps gain experience points to increase his level.

"Ms. Uehara... I have other things to deal with these two days. If you want to spar with me and see my strength, then wait until I complete my mission and come back in a few days."

Seeing that Mizuki Yu rejected his proposal to spar with him, Uehara Rin was a little disappointed but did not force it.

He didn't even ask what kind of tasks Shuicheng You needed to complete in the next few days, but just quietly changed his originally arranged itinerary.

Rin Uehara originally came here to see Asha during his free time, and to give some pointers to Yukikaze, his junior who had also awakened the Lightning Release Ninjutsu like himself.

According to Rin Uehara's original plan, she would stay here for two days at most and then return to Kyoto, but now that she has discovered the existence of Mizuki Yu, she plans to stay in Tokyo for a longer period of time.

"You-kun, don't be so polite when calling me Miss Uehara. Speaking of which, Senior Shiranui once visited our Uehara family before he retired. Our Uehara family and the Mizuki family can be considered old friends."

"You-kun, you can just call me by my name or call me Sister Lin."

"You-kun should have just joined Taimanin. I don't know how much Shiranui-senpai and Yukikaze have told him about Taimanin before. If there is anything you don't understand, you can come to me at any time. I should stay here for the time being."

The corners of Uehara Rin's mouth slightly raised to reveal a slightly charming smile, and she spoke to Mizuki Yu in front of her with an extremely enthusiastic attitude.

This sudden change left both Yazu Yukikaze and Mizuki Yukikaze stunned.

Especially Yukikaze, she stared at Uehara Rin with her eyes wide open, with an expression of disbelief.

Although Yukikaze was not particularly familiar with her teacher Uehara Rin, ever since she awakened her power and began to receive training in Taimanin, the teacher who was responsible for guiding her gave her the impression of being a very serious person!

Not to mention that he is always serious in front of her, but he rarely shows such a warm and gentle side.

As for the friendship between the Uehara family and the Mizuki family, what about old acquaintances...

As a Taimanin family with a history of hundreds or even thousands of years, in a country like Neon, which has a small land area, there are only a handful of families that can rank among the top.

Almost every Taimanin family has had more or less interactions or even intermarriages during the hundreds or thousands of years of their inheritance. If we have to talk about old friends, then all the Taimanin families can probably be considered old friends.

When Xuefeng saw Hara Rin's attitude towards her own onii-chan, she felt a little uneasy.

She always felt that this teacher Rin Uehara seemed to have bad intentions towards her onii-chan, but when she thought about the fact that Rin Uehara and her onii-chan were only meeting for the first time today, and that there was an age difference of nearly ten years between them, the kind of thing she thought should not happen!

"Mr. Uehara, you and Yukikaze should continue training here."

"I'm going to take Youjun to the back mountain for a walk and clean up some of the monsters hiding in the back mountain!"

Yazushiro looked at Uehara Rin and then cast her gaze at Yukikaze beside her. She seemed to have sensed that the atmosphere was a little unusual, so she hurriedly pulled Mizuki You and left the training ground and entered the special space in the back mountain not far away.

In the next few days, Mizuki Yu basically spent all his time killing monsters in the strange space in the back mountain that overlapped with the demon world. Occasionally, he would meet Yukikaze, Rinko, and some strange Taima ninjas he didn't know.

There is also the beautiful older sister Rin Uehara, who is very plump and sexy, and always comes to talk to him intentionally or unintentionally, and even gives Mizuki Yu the illusion that she likes him.

This peaceful monster-killing life lasted for almost three days. With the experience point bonus gained from teaming up, as well as the special bonus of the same experience point gained by teammates after killing monsters, in just three days, Mizuki Yu's strength had unknowingly improved a lot, and he was already close to the level of a senior ninja.

Three days later at the Taimanin Headquarters in Tokyo, according to reliable information provided by the logistics intelligence department, today is the day when the underground black market in Chiba will open.

When night fell, Mizuki You changed into a white singlet that looked very ordinary but had the Uchiha fan symbol printed on the back, left the headquarters of the Taimanin Organization, and came alone to the door of an abandoned building near Akihabara in Chiba.

This is the entrance to the underground black market mentioned in the intelligence!

As for why it was agreed that Yazushiro Yu would be responsible for this mission together with him, but Mizuki Yu was the only one there at the moment, it was because Yazushiro Yu said that her appearance was too familiar to those guys who were enemies of the Taimanin, so she could not enter the underground black market openly.

Let the unfamiliar face Mizuki You enter the underground black market first, and she will find another way to sneak in.

Although Yazu Yukari said so, Mizuki Yuu knew very well where Yazu Yukari was hiding!

At this time, Yazu Yukari and Igawa Sakura were both hiding in the shadows under their feet using Igawa Sakura's Shadow Release Ninjutsu. They thought that Mizuki Yu knew nothing about this, and they never imagined that Mizuki Yu could easily find their hiding places through the system.

Standing at the entrance of the Chiba underground black market, Shui Chengyou thought for a moment and used the transformation technique with his hands to slightly change his appearance.

If someone who has watched Naruto comes here, he will definitely be able to recognize at a glance that Mizuki Yuu now has the face of Uchiha Itachi.

Anyway, the first character he obtained after activating the system after traveling to this world was Uchiha Izuna, and even his own appearance was very similar to Uchiha Izuna.

It's not a strange thing to use Uchiha Itachi's appearance.

As Mizuki You walked into the abandoned building, after a brief period of darkness, light appeared before his eyes again.

At this time, Shui Chengyou was no longer in the abandoned building, but came to a bustling and lively street.

The street is brightly lit, with many pedestrians coming and going. It looks no different from the bustling streets in cities like Tokyo or Chiba at night.

Only people with keen perception and careful exploration can discover that there is some special power in the air here, perhaps magic or aura or something like that?

"This is Chiba's underground city. It looks like a city."

Shuicheng You stood on the busy street, looking at the bustling street with curiosity in his eyes, and couldn't help but sigh softly.

At the same time, Shui Chengyou's mind moved, and a translucent light curtain appeared in front of him.

Seeing the various data displayed on the character attribute panel in front of him, Mizushiro You opened the system map, on which he saw various small dots marked with different colors, as well as the location of the mission location.

According to the colors of the small dots on the map, most of the people in this underground black market are red, which means that these guys are hostile or are in the enemy camp with him.

According to the settings in the game, these red dots represent experience monsters that can be attacked and hunted!

Seeing the densely packed red dots on the system map, which varied in color from light to dark, Mizushiro You couldn't help but licking his lips.

He was able to directly improve more than 20 levels to a level close to that of a jonin in just three days. During these few days, he almost cleared out all the monsters hidden in the back mountain of the Taimanin organization's Tokyo headquarters base.

Of course, he also successfully triggered and completed several system-commissioned tasks and gained a lot of experience points, so he was able to level up so quickly.

There are so many red dots representing enemies in this underground black market. If he could eliminate all of them, he would definitely be able to break through to the level of Jonin, and even reach a strength close to that of Kage!

Although Shuicheng You really wanted to shut down this underground black market directly, he was still somewhat rational and quickly suppressed his crazy thoughts.

There are quite a few humans in this underground black market, as well as many demons, black-skinned elves with pointy ears and charming looks, and even ferocious-looking orcs. With his current strength, it is simply impossible to eliminate all the guys who are hostile to him or are in the enemy camp.

Even with the addition of Yazu Yukari and Igawa Sakura hiding in his shadow, it would still be difficult to achieve.

Unless he opens the Eight Gates directly, but Mizuki Yu doesn't want to be targeted by those truly powerful beings so early. Is it worth it for a few experience points?

For now, let's just investigate and collect information about man-made monsters.

Chapter 19: The brothel street in the black market?

Shuicheng You gave up the idea of eliminating all the humans, demons, orcs and other guys marked with red dots by the system in this underground black market as experience packs, and began to wander aimlessly on the streets of the underground black market.
