My Sister is Bronya

My Sister is Bronya Author: Bai Ri Zou

"Synopsis: Ishiu transmigrated.

He arrived in a world that seemed very dangerous.

This world had Honkai Beasts, Zombies, Mechs, and Valkyries.

And... Herrschers.

But it didn't matter, he had a system.

"Dead Apostle Ancestor, activate! Flash Blade - Seven Nights!"

A certain pufferfish: "Yameru!"

Schicksal: "Why is this man so strong?"

A certain person with a youthful appearance despite their age: "Ishiu, are you a Captain or a Valkyrie?!"

A certain twin: "Brother Ishiu is so amazing, I don't think I'm good enough for him... What nonsense are you saying?! Go and snatch him for me!"

A certain Bronya: "See that handsome guy? That's my brother! None of you are allowed to snatch him! Heavy Armored Bunny 19C!"

Chapter 1 Cocolia Orphanage

August 2013, Cocolia Orphanage.

Perched on a cliff by the sea, a somewhat slender figure sat on the edge, gazing at the vast expanse of blue sea not far away while silently counting.

"...598, 599, 600! Time's up!"

As he excitedly uttered the last few numbers, a devoid-of-emotion mechanical voice echoed deep within his mind at the same time.

[Ding! Congratulations to the host for completing the mission, sitting by the sea for ten minutes. Commencing random reward draw—]

[Ding! Reward draw successful. Congratulations to the host for obtaining one legendary Rainbow Lollipop— P.S.: Eat my lollipop, and you're mine.]

[Ding! Reward item has been sent to the system space. The host can claim it at any time.]

"Damn it!"

Ishiu's lips twitched. He felt like he'd been tricked by this brain-dead system again. Instead of enjoying his warm bed in the early morning, he came here to brave the cold wind, only to be given a lollipop in the end. Did they think he was a little girl or something?

[Ding! Mission rewards are completely random. Please maintain your composure, host. This system has the final right of interpretation.]

"Fine."

Ishiu sighed. What else could he say? It was better than a smelly sock, right?

--- Ishiu was a transmigrator, a fact he believed everyone could see. After being hit and killed by a car in his previous life, he inexplicably transmigrated to this world and was reborn into the body of a child who had died in the ruins of war. He was eventually rescued.

The system Ishiu possessed also suddenly appeared in his mind after he transmigrated.

Ishiu didn't know what this system was called. It was like an emotionless machine, only giving him missions and rewards, with no punishments.

At first, Ishiu thought he had struck it rich and could embark on the path of a 'Dragon King' like the protagonists in novels from his previous life.

But as time went by, the system dealt Ishiu a harsh blow with reality, making him understand what 'someone else's system' was like.

This system would issue missions to him without any warning, completely at random. The content and difficulty of the missions were also random, and the rewards obtained were equally random. The difficulty and rewards were completely uncorrelated.

For example, he might complete an extremely difficult mission but only receive a reward of... a bag of dumplings.

Yet, by casually sweeping the floor, he might obtain some precious rewards, such as martial skills, weapons, or money.

It was outrageous.

Ishiu turned his attention back to the sea before him. It was early morning, and the sun was slowly rising in the east. The first rays of morning sunlight gently caressed his body along with the refreshing sea breeze, blowing his black short hair, which hadn't been tidied due to waking up early, into a greater mess.

"Brother Ishiu, why did you come all the way here? Sister Bronya is looking for you everywhere."

Just then, a somewhat weak female voice sounded from behind him, drawing Ishiu's attention.

Without even needing to turn around, just by hearing that familiar voice, Ishiu already knew who was behind him. He scratched his head, smiled, and turned to the girl behind him, saying, "Why is she looking for me? By the way, Seele, how did you know I was here?"

As Ishiu turned, a very cute girl came into his view.

She was a girl about 1.5 meters tall, with shoulder-length blue-black hair, ocean-blue eyes, and snow-white skin. She was so adorable she seemed like a fairy not of this world.

Her name was Seele Vollerei, and like Ishiu, she was an adopted child of Cocolia Orphanage.

Because she was younger than Ishiu and had not been at the orphanage as long as him, coupled with Ishiu's usual care for her, Seele called Ishiu 'brother'.

"Brother Ishiu, did you forget what we agreed on yesterday, that you would practice martial arts with Sister Bronya?" the blue-haired, blue-eyed girl chuckled lightly, her eyes curving into crescent moons, her voice gentle and clear. "Also, I happened to see you leave from the window."

"Uh... okay." Ishiu pushed himself up from the ground with his hands.

He was ten centimeters taller than Seele. After all, his current body was only fourteen years old and not fully developed. However, even so, he was still the tallest in the orphanage.

And his looks weren't bad either; in terms of pure appearance, he could rank in the top five in the orphanage.

Casually dusting himself off, Ishiu took a deep breath and smiled at Seele, "Let's go, we're heading back."

"Okay." Seele nodded obediently and walked alongside Ishiu towards the orphanage.

"Oh, right, this is for you." Halfway down the road, Ishiu seemed to suddenly remember something. He pretended to search his pockets, but in reality, he took out the rainbow lollipop rewarded by the system from his system space and offered it to Seele.

"Wow! Such pretty candy." Seele took the lollipop with a bit of surprise, then held it up to examine it.

Although the system was a rip-off, he had to admit that everything it produced was of excellent quality.

Even this lollipop, in terms of taste and appearance, was top-notch. It was definitely a killer move, a treasure, for tricking... ah, no, for giving to little girls.

"I'm glad you like it." Seeing Seele's happy smile, Ishiu felt good too. After all, nothing was more healing than seeing a super cute girl's smile first thing in the morning.

If there was, it would definitely be two girls!

"Right, Ishiu-niichan, where did you get this candy? It's not from..."

"Don't ask. Just say it's magic."

Because Ishiu often got strange things from the system, he simply gave some of the delicious or fun little items to the children at the orphanage. As a result, his popularity there was only second to Bronya, the 'child king'.

And whenever people asked him where he got these things, his answer was always: "Because I know magic, I can make a lot of things appear."

"As expected..." Seele sighed like a little adult. She knew Ishiu would say that, but she wasn't like the children under ten at the orphanage who could still believe his nonsense.

However, the well-behaved and sensible Seele naturally wouldn't press Ishiu for answers. Everyone had their own secrets, after all.

Besides, the lollipop was really delicious~

Mmm, mmm~~

The two chatted as they walked, and soon returned to the orphanage.

This orphanage was built by Cocolia. All the children here were orphans she had adopted. In Ishiu's memory, Cocolia always seemed very busy and rarely had time to visit them, so most of these children were looked after by Bronya and him.

Chapter 2: A World Belonging to the Honkai

"Ishiu, you went out playing again."

Just as Ishiu and Seele reached the main entrance, a voice, deliberately cold but unable to hide its childishness, came from behind the gate.

As the voice sounded, a petite figure emerged from inside.

It was a girl whose cuteness was in no way inferior to Seele's.

Her hair was silver-gray, styled into two wavy twin tails tied neatly behind her head. Her face was small, with delicate features, and her skin was as white as snow, like a work of art meticulously carved by God, so perfect that not a single flaw could be found.

If one had to find fault, it might be her chest... cough, never mind, let's not say hurtful things.

And her name was Bronya Zaychik, a genuine little Russian girl.

Seeing the girl standing before him with a poker face, seemingly unable to discern her emotions, Ishiu scratched his head and said with a simple laugh, "I was just out for a walk. The weather's nice today. I think Bronya, you could also go out for a walk, get some sun, maybe you'll grow taller~"

Bang!

Bronya's eyes sharpened, and she punched Ishiu squarely in the stomach.

Ishiu gasped, clutching his stomach and stumbling back a few steps. He grimaced in pain, but thankfully Seele quickly supported him, preventing him from falling to the ground in embarrassment.

Bronya shook her hand and looked at Ishiu expressionlessly. "You should call me Bronya-neechan. Also, don't joke about Bronya, or Bronya will let you taste the iron fist of your sister."

"You... you already hit me." Ishiu rubbed his stomach. Bronya's punch hurt, but she had a good sense of control. It only caused him some superficial pain, and he'd be fine in a while. It was much gentler than during sparring.

Ishiu pouted. "Besides, I'm older than you. You should be calling me 'niichan'."

Bronya shook her head righteously. "Negative. Bronya is one month older than you. You should call me 'neechan'."

"Negative! How am I a month younger than you?"

"Mom said so."

"Uh..." Ishiu's mouth twitched. Although he didn't know the exact age of this body, his inner self was a genuine twenty-three-year-old adult soul. Asking him to call a one-meter-five little pudding 'neechan' was indeed a bit too much to ask.

"Ahem, Bronya, didn't we agree to practice martial arts yesterday? Let's not waste any more time. Let's go now." Ishiu changed the subject.

Bronya glanced at him sideways, a hint of a smile appearing in her eyes, but it quickly vanished.

"Have you had breakfast yet?"

"Not yet."

"Then go eat first. I'll wait for you in the training room."

"Okay."

With that, Bronya turned and left.

"Ishiu-niichan, does it still hurt?" Seele looked at Ishiu's stomach with concern and asked softly.

"It doesn't hurt." Ishiu shook his head and smiled. "Don't mind my acting like I was dying just now. That was all for the little pudding. Otherwise, how could she have let me off so easily?"

"Pfft—" Hearing Ishiu's words, Seele couldn't help but let out a giggle, her sapphire-blue eyes curving into crescents. "Ishiu-niichan, you called Bronya-neechan 'little pudding' again. If she hears you, you'll get hit again."

"So just don't let her hear it, right? You're not going to rat me out to the little pudding, are you, Seele?"

"Heh heh, who knows~~" Seele, uncharacteristically mischievous, giggled, spun around, and headed towards the cafeteria. She hadn't eaten breakfast either, in order to find Ishiu.

"Hey, hey, no way, Seele! You can't set me up like this. I just gave you candy." Ishiu quickly followed, saying with a pained expression, but the only response he received was the girl's bell-like laughter.

"Hee hee~~"

After finishing their meal, Ishiu and Seele went to the orphanage's training room.

Seeing this, some students might wonder why there's a training room in the orphanage.

The answer is simple: the world Ishiu is in isn't ordinary and peaceful like his previous life.

This world has been invaded by an energy called Honkai. Honkai energy is highly contagious and infectious, much like a zombie virus in movies, but even more terrifying.

People infected by Honkai turn into monsters called Zombies. They lose all reason and only kill any living thing within their sight.

Furthermore, with the invasion of Honkai energy, another type of monster, the Honkai Beast, has sounded the horns of war against humanity.

Honkai Beasts possess immense destructive power and regenerative abilities. Even human firearms struggle to kill them, and they seem to be endless, as if they can never be wiped out.

To combat the Honkai Beasts, the people of this world have employed various methods, though Ishiu doesn't know many of them. He only knows that there's a profession called Valkyrie, specifically tasked with fighting Honkai Beasts.

Besides that, there seem to be other means. For instance, Cocolia, who adopted him, is an important member of an organization that fights against Honkai.

Ishiu once asked about these matters, but Cocolia never answered him directly. She would just smile, pat his head, and say it wasn't something a child like him should worry about, which always left Ishiu speechless.

This training room, however, was specifically built for children in the orphanage who show potential.

Some children in the orphanage have the talent to control this Honkai energy. Therefore, Cocolia built this training room to hone their abilities and train them in various skills.

What made Ishiu a bit speechless was that all the children who could control Honkai energy were girls, not a single boy among them. Of course, that included him.

But as someone with the soul of an adult, how could he be content being outdone by a bunch of young girls? Plus, he had the system's help. Although it was a rather unreliable system, it was still better than nothing.

So, he often trained in the room, improving his physical fitness and learning combat-related skills.

For example, he is currently learning martial arts from Bronya.
