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

Author: Xiaobaigu

Summary:

Mizuki You was hit by a truck during a job interview. When he woke up, he found that he had traveled to a parallel world and turned into a child. He was picked up by a plump, mature and sexy older sister and taken home.

I originally thought that I could live the comfortable life I always dreamed of, but I found that something seemed to be wrong with this world!

The mature older sister who took him in is called Mizuki Shiranui, a Taima Ninja. Shiranui's daughter, his non-blood-related sister, is called Mizuki Yukikaze. The new lady who moved next door, Mrs. Shendong, is a snow woman. And a classmate who was on good terms with him suddenly turned into a succubus?

Someone in the school is holding a mobile phone and is ready to use software to hypnotize all the girls. The female knights of the demon world are trying to seduce them to join the demon clan. In this somewhat broken world, Shui Chengyou just wants to protect the people around him and keep them from being coveted by various yellow-haired people.

But they asked why everyone was relying on them?

Volume One

Chapter 1: My sister is going to become a Taima Ninja too?

It was about 6 or 7 in the afternoon in mid-December, and the sky was gradually getting dark on the streets of Tokyo.

A tall, thin, handsome boy wearing the uniform of the private Johshin Academy was yawning and strolling lazily on the busy street.

"君の前前世からservantは君を探しはじめたよ

"そのぶきっちょな笑い方をめがけてやってきたんだよ"

Suddenly, a melodious cell phone ringtone sounded, which made the boy, who was still a little sleepy, perk up a little. He took out his cell phone from his pocket, glanced at the caller ID on the screen, and answered the call.

"You-chan, I have some work to take care of tonight, and Xuefeng will also go with me to take care of those work matters. I have prepared dinner in advance and put it in the refrigerator. Remember to heat it up yourself when you get home."

"Although the school will be on winter vacation starting tomorrow, you can't play games too late tonight even if I'm not at home."

After the call was connected, a hoarse voice mixed with a hint of charm came from the phone, and Shuichengyou was given some earnest instructions.

"Aunt Shiranui, what work are you doing tonight that requires Yukikaze to go with you?"

"Could it be that you have become a Taimanin again and are going to defeat those monsters and demons, even that girl Yukikaze?"

Shui Chengyou was walking beside the city street, holding his cell phone with a frown on his face, and subconsciously quickened his pace.

As a time traveler, he knew from the very beginning the identity of the beautiful elder sister Mizuki Shiranui, the Taimanin, who had taken him in when he was homeless.

However, with the appearance of Mizuki Yuu and the gradual growth of his non-blood-related sister Yukikaze, Mizuki Shiranui has retired and left the front line of fighting monsters and demons.

If possible, Mizuki Yuu does not want Shiranui to become a Taimanin again and continue her previous dangerous life, nor does he want Yukikaze to follow the path of a Taimanin.

Although there may be many dangers in this world, Mizushiro You feels that with the golden finger that he finally awakened some time ago, he should still be able to protect them!

"Don't worry, You-chan. Although I haven't killed monsters for a long time since I retired, it doesn't mean that my strength has declined."

"I am only here to accompany Yukikaze this time. As a new Taimanin, the missions she needs to perform are usually not difficult. Besides, there are other teammates here, so there won't be any danger."

Hearing Shiranui's confident words on the other end of the phone, Mizuki You couldn't help but roll his eyes and couldn't help but recall the scene when he had just traveled to this world.

He still remembered that before he traveled through time, he had planned to find an internship during the National Day holiday. However, on his way to a company for an interview, when he passed a traffic light that would take at least two or three minutes to get up, he stood outside the crosswalk, took out his phone and opened the Naruto mobile game while waiting, a semi-trailer loaded with building materials suddenly rushed out from a distance and crashed straight into him!

When he came to his senses, he found himself in an unfamiliar abandoned factory. His body seemed to have shrunk to become a child of only six or seven years old. In front of him stood a beautiful older sister in a tight-fitting outfit with an amazing figure!

According to Mizuki Shiranui, he suddenly appeared from the sky and landed right in front of her.

It was also because of Mizuki Yu's sudden appearance that he just happened to kill a tentacle monster hiding in the dark that attempted to sneak attack Mizuki Shiranui.

Afterwards, the homeless Mizushiro Yu, who had just traveled to this strange world, was taken home by Mizushiro Shiranui and taken in. He was named Mizushiro Yu even though he could not remember his original name.

"No matter what, you should be careful when facing those cunning monsters. Don't be careless!"

"Even if you are very strong, you must not be careless. Where are you going to carry out the mission this time?"

Recalling what happened when he first crossed over to this world, Mizushiro You couldn't help but give a few more instructions.

If he hadn't appeared at that time, Mizuki Shiranui would most likely have been successfully ambushed by the tentacle monster hiding in the dark, and then captured and trained into a fluff ball!

Moreover, from the Taimanin-themed anime works he had watched before he traveled through time, most of the Taimanin who were captured by the enemy were not defeated because they were too weak. They were basically caught because they underestimated the enemy and became careless or fell into the enemy's trap, and were played all kinds of tricks by the enemy.

Although it is not clear whether the Taimanin in this world will unfold the plots of those previous anime works, it is still necessary to remind Aunt Shiranui a few more times.

"Don't ask about the specific content and location of the mission, You-chan. These are things that need to be kept confidential."

"Anyway, don't worry about me and Yukikaze. That's it. I have to go get ready."

As Mizuki Shiranui finished her words, the phone was hung up.

"Forget it, let's just secretly follow and see what's going on, in case something really happens!"

Shui Chengyou said secretly in his heart, and suddenly a translucent light curtain appeared in front of him.

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

Age: 17

Level: 61 (Elite Chunin) 2545/85000

Bloodline: Sharingan (Eye Power 965/1000) +

Current accepted tasks: None

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

Looking at the somewhat crude panel in front of him, Shuicheng You couldn't help but smile slightly.

This is the golden finger he obtained after crossing over to this world. It is the embodiment of the Naruto mobile game he was playing before crossing over.

This golden finger was officially activated more than a year ago, after he entered high school.

It took more than a year to reach the level of elite Chunin, which was considered to be a bit of strength.

Mizuki Yu estimated that his current strength should be about the same as Sasuke during the Chunin Exams, maybe slightly stronger than him, but there was a clear gap compared to the strong ones.

It’s a pity that the character he used before traveling through time was Uchiha Izuna. If it was the character template of Madara or Hashirama, his current strength would probably be even stronger!

After closing the character attribute panel, Mizuki Yuu suddenly opened the map function in the game system.

A map depicting the entire Tokyo and the routes of the surrounding cities suddenly appeared in front of him, and Mizushiro Yuu and two small dots flashing green light representing the same camp appeared on both sides of the map.

Through the system's map function, not only can the location of Aunt Shiranui and Yukikaze be determined, but their current status can also be checked through the map. Mizuki Yuu does not need to worry about them encountering any danger for the time being.

They probably haven't encountered any monsters yet.

Mizushiro You rushed home as fast as he could, threw his schoolbag on the sofa, took off his Joshin Academy uniform, changed into a set of red armor with a round fan mark, the same as Uchiha Madara's, put a long sword on his waist, covered half of his face with a mask, leaving only a pair of scarlet eyes, and went out.

Around eight o'clock in the evening, Mizuki You noticed that the two green dots of light representing Shiranui and Yukikaze on the map began to move. He immediately used the teleportation technique to travel through the streets of the city. In less than ten minutes, he arrived at his destination right behind Shiranui's mother and Yukikaze!

It was a long-abandoned hospital in Chiba City. Even standing outside the door, it gave people a gloomy feeling.

Looking at the abandoned hospital in front of him, the three black magatama in Mizuki You's eyes slowly rotated.

"Is this the location where Xuefeng will carry out his mission this time?"

Mizushiro You looked at the abandoned hospital in front of him, took a closer look, and then took a step forward to go in and take a look!

What Shuicheng You didn't expect was that he had just taken a few steps forward and hadn't even approached the hospital gate when he suddenly felt a sense of crisis.

With the insight and dynamic vision of the Three-magatama Sharingan, even in such a dim night he still saw a figure rushing out from the grove next to the abandoned hospital at a very fast speed, holding a huge axe in both hands and slashing at him fiercely.

"Boom~!"

Faced with such a powerful attack, even though Mizujo You was quite confident in his own strength, he did not dare to take it head-on.

After all, the initial character he obtained when activating the golden finger was Uchiha Izuna, not Hashirama Senju or Tsunade, and his strength was not as good as Hashirama and Tsunade who had super powers.

Fortunately, Mizuki You discovered it in time and used the technique of instant body movement to narrowly avoid the axe that was chopping towards him.

The giant axe fell on the place where Shui Chengyou had previously stood, creating a large hole that was at least several dozen centimeters deep, and dust flew everywhere in an instant!

"What is the purpose of this guy who is hiding his head and showing his tail, following us here quietly?"

"You are dressed like this, and you have a power that is completely different from our anti-demon factor and the magic power of the demons. Who are you?"

Seeing that Shuicheng dodged the attack in time, the tall and plump girl holding the giant axe, wearing a white tight combat suit and a high ponytail, looking quite heroic did not take the opportunity to continue attacking, but stopped in front of Shuicheng You and questioned loudly.

Looking at the girl standing in front of him, Shui Chengyou frowned slightly.

I felt a little unhappy about the other party's indiscriminate attack on me.

Just from the attire of the girl in front of him, he could roughly infer that she should also be a member of the Taimanin. And seeing that she looked somewhat familiar, she was probably the heroine in a Taimanin anime he had watched before traveling through time.

Mizuki Yuu didn't want to be an enemy of the girl in front of him. After all, according to the location shown on the map, Shiranui's mother and Yukikaze should be here.

After a little thought, Mizuki Yu raised his hand and slowly took off the black mask that covered half of his face, and decided to confess his identity directly.

"My name is Mizuki Yuu, and I am not your enemy."

"I came here just to look for someone, and by the way, I can also help you get rid of the monsters hiding in this abandoned hospital."

As Shuicheng You took off his mask, he took the initiative to reveal his identity

Yatsu Shi, who was standing in front of him, muttered a few words quietly, and had some guesses about Mizuki Yu's identity in her heart.

However, a cry of surprise was heard from a shadowy corner outside an abandoned hospital not far away.

"How could it be Xiaoyou?"

"This mysterious guy turned out to be Onii-chan?"

Along with a few voices full of surprise and astonishment, three figures wearing tight combat suits walked out one after another from the corners and woods covered by shadows.

Compared to the somewhat unfamiliar Yazu Yukari who was standing in front of him, the few people who appeared at this time were all people that Mizuki You were extremely familiar with.

The first person he met after crossing over to this world was Aunt Shiranui, who took him in when he was homeless, as well as his non-blood-related sister Yukikaze and his childhood playmate and childhood sweetheart Rinko Akiyama.

Mizuki Yu's eyes swept across several people, and his gaze paused for a few seconds on the chests of Shiranui's mother, Rinko, and Yukikaze.

Aunt Shiranui has a plump figure and the charm of a mature woman, which Mizuki Yu has long experienced. Rinko seems to have become more mature after not seeing her for a while.

However, judging from her figure alone, it is really hard to associate Xuefeng with a 16-year-old high school girl. She is obviously Aunt Shiranui's biological daughter, but it seems that she has not inherited Aunt Shiranui's good genes at all?

"Yuu-chan, what's going on?"

"Let's not talk about your outfit, how do you have such power, and what kind of power is it?"

Just as You was admiring the graceful and attractive figures of Shiranui's mother and Rinko under their tight combat suits, a sudden voice interrupted his thoughts.

Chapter 2: Taimanin... No, it's Naruto!

Mizushiro Yu, whose thoughts were interrupted by the sudden voice in his ear, withdrew his gaze from Aunt Shiranui and Rinko, raised his head slightly and looked directly into the eyes of the people in front of him.

"This is a power called Chakra that I accidentally awakened some time ago. Although it is different from the power possessed by Taimanin, it is also called ninja."

"Chakra is a type of energy produced when the human body perfectly integrates the energies of all components. It can also be understood as a product of an even mixture of physical energy and spiritual energy."

Mizuki Yuu, Aunt Shiranui, Rinko, Yukikaze and the others briefly explained about chakra, a completely new system of power that had never appeared in this world before, but they didn't go into detail about how he obtained chakra.

Of course, Shiranui, Rinko, and even Yazushiro who was standing by did not continue to ask questions.

It would be enough as long as we can be sure that Mizuki You was not bewitched by demons or some evil demons and contaminated by the demonic power to gain power.

As for how Mizuki Yu obtained the unprecedented power of chakra, it is not that important.

"Yuu-chan, even if you gained power by accident, you haven't received any professional training, so why are you coming here to join in the fun?"

Although she was pleased and happy that Mizuki Yu had obtained chakra and had the power to protect herself, Mizuki Shiranui did not show this joy.

Instead, he glared at Shui Chengyou, who was fully armed with red armor, and shouted in a deep voice:

"Don't keep messing around here. Do you think defeating monsters is just a game? I, Yukikaze, Rinko and the others are here and that's enough for us. Why don't you just go home!"

Although Mizuki Shiranui had previously told Mizuki You in a relaxed tone on the phone that the subjugation mission she and Yukikaze were going to carry out this time was very simple and there would be no danger at all.

But the actual situation is far from as simple as she said. Even the easiest tasks may encounter unexpected changes and various dangers.

The reason why she and Yukikaze became Taimanin was because the Mizuki family itself was a Taimanin family with hundreds or thousands of years of heritage. Even if they wanted to live a peaceful life like ordinary people, it was difficult to guarantee that they would not be targeted by the Mizuki family's former enemies.

Mizuki You is different from them. Even though he also has the surname Mizuki, he does not have the blood of the Mizuki family. He does not need to embark on this path of constantly fighting monsters and demons and walking on the edge of danger.

"Aunt Shiranui, although I have not received professional training and instruction, I have encountered monsters after gaining power, so I do have some combat experience."

"So let me go with you to defeat those monsters. I also want to use my own strength to protect Aunt Shiranui and Yukikaze... and people like Rinko who are very important to me!"
