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

After a long while, I felt the sweet taste in my mouth and my hands stretched out involuntarily.

Mizuki Yuu and Mizuki Shiranui stayed in the room for about half an hour until they heard noises coming from the bathroom next door and found that Xuefeng had finished her shower. Then they tidied up their messy clothes and walked out of the room one after another.

"Remember not to tell Xuefeng about what happened today. You are already an adult, but I didn't expect you to like drinking milk so much. You are very similar to me when you were a child."

"A few years ago, when you found out what the 'milk' I was preparing for you was, you showed great resistance. But just now, I didn't see any resistance from you at all."

Outside the bedroom, there was still a blush on Mizuki Shiranui's fair cheeks that had not completely faded. She looked meaningfully at Mizuki You beside her and said with a hint of teasing.

"You-chan used to be very mature. Sometimes I didn't even know who was the child who needed to be taken care of, you or me. I didn't expect that when we were in the room before, You-chan finally showed her childish side!"

"This behavior reminds me of a saying from Shenzhou."

"I remember it was called... milk poop or something?"

Mizuki Shiranui looked at the older Mizuki Yu standing next to her with a playful smile, and said something in Chinese in a somewhat strange tone that Mizuki Yu had not heard in many years.

Although he felt that the long-lost Chinese language was somewhat familiar, he always had a very strange feeling.

Just now, when he was in the room drinking the special 'milk' prepared by Aunt Shiranui to replenish his nutrition, he could not help but shout out the name 'Mom'. It was a completely subconscious behavior.

"You-chan, go to bed early today, and come with us tomorrow morning to meet Asha-ji at the headquarters of the Taimanin Organization in Tokyo."

"Asha is the current captain of the Taimanin. If you want to join the Taimanin organization, you must get her consent. And it just so happens that this time I can find someone to help you check your body to see if there are any hidden dangers in your newly awakened energy called chakra!"

Mizuki Shiranui smiled and said a few words to Mizuki Yuu, then waved at him and went downstairs.

Chapter 12: Buy Ninjutsu and Upgrade

When Mizuki Shiranui walked to the stairs, the door of the bathroom not far from the bedroom was suddenly pushed open from the inside, and Xuefeng, who had just finished taking a bath and whose hair was still a little wet, appeared in front of Mizuki You.

Perhaps it was because she had believed her mother's words before and thought that massaging acupoints could effectively stimulate development. Xuefeng, who had just walked out of the bathroom after taking a shower, was only wearing a thin nightgown and no underwear.

At this time, Xuefeng was holding a mobile phone in one hand and had specially found a teaching video about using massage methods to make herself more plump. While listening to the explanation of the blogger in the video who looked like he had a heavy chest, she imitated the movements in the video and pressed and groped her chest through her clothes.

As a qualified Taimanin, during the training process, he had learned about the acupuncture points throughout the human body, so it was very easy for Xuefeng to learn massage.

"Onii-chan... and mom, why are you here?"

"Mom, do you want to take a bath? I haven't drained the hot water from the bathtub yet. I...I'll go back to my room first!"

Mizuki Yukikaze didn't expect that she would be caught by her onii-chan and her mother while secretly watching those videos about breast massage and enlargement. She felt a sense of shame for no reason in her heart. She quickly put down her hands that were on her chest, locked her phone, and rushed back to her room.

It was also because of this that Mizuki Yukikaze, who rushed back to her room in a hurry, did not notice anything unusual about Mizuki Yu and Shiranui.

"Xuefeng seems to be very concerned about her figure, but fortunately, Xuefeng's attention was not on us just now. Xiaoyou, you should go back to your room and take care of it."

"Next time when Xuefeng is at home, I won't give you such a reward again."

Mizuki Shiranui stopped and turned to look at Mizuki Yuu behind him. After making sure that Yukikaze had returned to her room, she gave Mizuki Yuu a displeased look and lowered her voice.

Just now, Xuefeng suddenly walked out of the bathroom after taking a shower and ran into them. Mizuki Shiranui was completely worried, fearing that Xuefeng would notice something.

Although she and Xiaoyou didn't do anything particularly out of the ordinary in the bedroom before, she only prepared some milk for Xiaoyou to supplement his nutrition.

At most, the method of feeding Mizuki Yu was a little different from usual, more like feeding a newborn baby.

But the wet part of Shiranui's clothes on her chest and the bulging pants of Mizuki Yuu would easily cause misunderstanding if people noticed it.

"Aunt Shiranui, this isn't my fault. I can't control my body's instinctive reactions."

"In the final analysis, it's because Aunt Shiranui is too attractive. Who can resist such temptation? To be precise, this is still your responsibility, Aunt Shiranui!"

Mizushiro Yu's eyes followed the gaze of Aunt Shiranui in front of him, and he quickly realized what she wanted to express. He could only laugh twice and argue in a low voice.

"If it's my responsibility, You-chan wouldn't want to go even further and ask me to leave to help you solve these problems, right?"

"You've already received the reward. If you want more rewards, you can wait until next time when You-chan does something pleasing and satisfying. I'm going to go downstairs to clean up and then go back to my room to rest. You should try to solve the problems you encounter today!"

Mizuki Shiranui raised the corner of her mouth slightly and left Mizuki You with a few thought-provoking words, then she no longer paid attention to Mizuki You behind her and continued to walk down the stairs.

Looking at Aunt Shiranui's back gradually disappearing from his sight, Mizuki You couldn't help but reveal a strange and surprised look on his face.

He traveled to this world and was taken back to the Mizushiro family by Mizushiro Shiranui. They have lived under the same roof for almost ten years. Although Shiranui sometimes has no defenses in front of him, they even changed clothes in front of him and took a bath together until a few years ago.

But apart from these, nothing more intimate had ever happened between Mizuki Shiranui and him.

Mizushiro You didn't expect that after Aunt Shiranui gave him a reward today, she would actually say that if he did something that made him satisfied or happy next time, she could give him some other rewards, even if he made some unreasonable requests.

I don't know if it was because the two of them had done some more intimate actions in the room before, which made Mizuki Shiranui's defenses in her heart gradually collapse.

But no matter what the reason is, Mizushiro Yu does not suffer any loss at all.

After Mizuki Shiranui left, Mizuki looked down at himself and turned to walk into the bathroom on the second floor.

After thirty or forty minutes of self-adjustment, Mizuki Yuu's heart, which had become restless because of Aunt Shiranui, was calmed down, and after washing up, he returned to his room.

Sitting on his bed, Shuicheng You took out the sealing scroll from the system backpack and instantly put the red Warring States style armor he was wearing into it.

Available missions: A-level Defeat the Fallen Demons, A-level Destroy the Monster Stronghold, B-level True Ninja, B-level Monster Killer...

Taking advantage of the fact that there is nothing else to do now and that no one will disturb him for the time being, Shui Chengyou thought about it and silently called out the system panel.

By killing monsters and completing commissioned tasks randomly triggered by the system, Mizuki You has accumulated more than 700,000 experience points, which is enough for him to upgrade several levels in a row. Even if he does not use all the experience points to improve his character level, he can use it as currency to buy some necessary ninjutsu in the system mall.

The awakened cheat code that accompanied him to this world was very similar to the Naruto mobile game he had played before crossing over, but it was not exactly the same.

The Naruto mobile game that Mizuki Yu played before he traveled through time gave him silver rewards in addition to experience points for each mission he completed. Silver, as the basic currency unit in the game, can be used to purchase basic medicines and items such as military pills and kunai.

As for other precious props, mission cards and precious ninjutsu, in addition to obtaining them through missions and activities, another way is to obtain them through krypton gold.

Unfortunately, the golden finger that was awakened after traveling to this world requires experience points to be consumed whether it is upgraded or to purchase any items through the system mall.

Even if Mizuki Yu wanted to spend money, he couldn't do anything!

If he could use real-world currency to spend money, he should have already raised his level to above Kage or even to the level of Six Paths Sage in the more than a year of the awakening system.

"As for ninjutsu at the moment, the Uchiha clan's most proficient fire escape combined with the Sharingan's illusion should be enough for the time being."

"The Mangekyō Sharingan cannot be forcibly upgraded through experience points for now, but you can consider learning the Eight Gates Ninjutsu, as a trump card in the future."

Mizuki Yu looked at his character attribute panel, secretly calculating his current shortcomings in his mind. Although according to the system's level classification he was only an elite Chunin, Mizuki Yu was fully confident that he could defeat the Jonin from the Naruto world.

Of course, people like Mike, who was able to open the Eight Gates and almost kicked Madara in the Six Paths Mode to death with one kick, are not included.

Mizushiro Yu opened the system mall and browsed through the various products therein, and selected the Eight Gates Ninjutsu Formation in the Ninjutsu category.

The price of the Eight Gates Ninjutsu Array in the system mall is not particularly expensive, and it only costs 200,000 experience points to purchase it.

Without any hesitation, Mizuki Yu spent 200,000 experience points to purchase the Eight Gates Ninjutsu and chose to learn it directly.

As the scroll recording the Eight Gates of Ninjutsu in Mizushiro Yu's hand turned into a stream of light and sank into Mizushiro's forehead, a stream of information containing countless contents directly poured into his mind.

After digesting these memories that suddenly emerged, Shuicheng You clenched his fists, and a look of eagerness to try flashed in his eyes.

After looking at his remaining experience points, Mizuki Yuu hesitated for a moment and chose to upgrade his level.

Name: Mizuki Yuu (Character template: Uchiha Izuna, break through the Kage level to open the second character)

Age: 17

Level: 65 (Elite Chunin) 165565/155000+

After advancing four levels in a row, he could not help but smile as he felt the chakra consumed in his body and the power of his Sharingan instantly restored to full capacity.

He was now looking forward to going with Aunt Shiranui and the others to meet the strongest Taima Ninja Asaki tomorrow.

I don’t know what level my current strength is among the Taimanin.

Author's Note: I came back a little late today. Chapter 2 was probably around 2 or 3 in the morning.

Chapter 13: Snow Wind Attacks at Night

After feeling the improvement of his chakra level and pupil power, Mizuki You thought for a while and bought a few detoxification pills from the system mall and put them in his backpack. He looked at the time, turned off the lights in the room, sat cross-legged on the bed and began to meditate with his eyes closed.

After activating the binding system, although the fastest and most convenient way to become stronger is to gain experience points to increase your level and learn ninjutsu by killing monsters and demons or completing various tasks randomly issued by the system, you can also choose to practice on your own.

Just relying on one's own efforts to practice and train will definitely not make you stronger as fast as using experience points to increase your level.

However, Shuicheng You has already gotten used to this kind of thing. As his strength gradually increases, his need for sleep also decreases.

What's more, every upgrade would restore his condition to its peak. At this time, Mizuki You didn't feel sleepy or tired at all.

Mizuki You was sitting cross-legged on the bed in a dark room, silently refining chakra. After an unknown amount of time, Mizuki You, who was immersed in practice, suddenly opened his eyes.

He seemed to hear a rustling sound of footsteps coming from outside the door, and finally seemed to stop at the door of his bedroom?

"Squeak~!"

After the footsteps outside the door stopped, about two or three minutes later, Mizuki You noticed that the door of his bedroom was slowly pushed open.

Looking at the figure that sneaked into his room from outside the door in a somewhat sneaky manner, Shuicheng You frowned slightly and sat on the bed without rushing to turn on the light.

Although the room was pitch black without turning on the lights, Mizuki Yu was able to barely see the outline of the figure that sneaked into his room with his Sharingan.

"Xue Feng?"

"Why are you coming to my place so late at night instead of sleeping in your own room?"

Seeing the sneaky figure approaching him stealthily, Shui Chengyou reached out to turn on the bedside lamp and asked with a hint of doubt in his tone.

Besides him, there were only Aunt Shiranui, Sister Rinko, and Yukikaze in the Mizuki family mansion. Even though their faces could not be seen clearly in the dark, one could tell that the person who came was Yukikaze just by their figure.

"Onii-chan...it's already so late and you haven't slept yet?"

Under the not particularly bright light at the head of Mizuki You's bed, Mizuki Xuefeng, who was wearing a thin nightgown, looked up at Mizuki You who was sitting on the bed. There was a hint of surprise in her eyes, and the corners of her mouth raised slightly to reveal a slightly embarrassed smile.

"I can meditate instead of sleep, but Xuefeng, you sneaked into my room at this time, are you planning to attack me at night?"

"It's really bold to choose tonight as the time. Not only is Aunt Shiranui at home, but Sister Rinko is also staying here. You are not worried about being discovered by them at all."

Mizushiro You looked at Xuefeng who seemed a little embarrassed in front of him, and a barely perceptible disappointment flashed in his eyes.

When he heard the rustling footsteps outside the door, he thought it was Aunt Shiranui who was going to give him some different rewards, but he never thought it would be Yukikaze.

"What about a night raid... I... I wouldn't do that!"

"I just want you to do me a favor, Onii-chan, help... help me... Forget it, Onii-chan, you should go to bed early!"

Seeing that Xuefeng seemed to want him to help with something, but he was hesitant in speaking, he even gave up his original idea and turned around to leave.

This made Shuicheng You even more curious, and he quickly got out of bed and walked two or three steps to Xuefeng.

"If you need my help with anything, just tell me. Why do you look so embarrassed?"

Mizushiro You looked at Xuefeng, whose face was flushed and eyes were evasive, and noticed the mobile phone in her hand. With some suspicion, he snatched the phone from Xuefeng's hand, unlocked the screen and saw the picture displayed on it.

It was a video that was paused on the video website. Based on the title and subtitles of the video, Mizuki Yu roughly understood that this was a video that taught people how to improve their body shape, especially how to make their barren chests become fuller and more upright.

"You sneaked into my room late at night without telling Aunt Shiranui and Sister Rinko. Could it be that you wanted me to give you a massage on your body?"

"Although this video says that asking a male friend to help with the massage can have a better effect..."

Mizuki You's gaze stayed on the video displayed on the mobile phone screen for a few seconds, and suddenly he felt that the phone he snatched from Xuefeng had become a little hot.

Although he knew that Xuefeng might have been well taken care of by him since she was a child and was somewhat dependent on him, he really didn't expect that Xuefeng would come to him for help even with such a private matter.

It is true in the video that the best effect can be achieved by having the opposite sex, preferably a boyfriend, help with the massage, but isn't it inappropriate for him to help Xuefeng do such a thing given his identity?
