My Sister Is Bronya

"You... defeated a Ballista-class Honkai Beast? Why?" Bronya's brows furrowed. No one understood Ishiu better than she did. She knew very well that the guy only had a decent face; nothing else about him was worth mentioning. Yet, this person had defeated a Ballista-class Honkai Beast.

If it were any other member of the Seven Nights clan, they might have maliciously speculated whether Ishiu used some underhanded tactics or found a bug in the Imaginary Space. But Bronya wouldn't think that way. The former was irrelevant; no method was too extreme when dealing with Honkai Beasts. As for the latter, it was impossible. Ishiu didn't have the capability to find bugs in the Imaginary Space.

Facing Bronya's question, Ishiu simply smiled slightly and shrugged, saying, "It's simple. I charged over, cut it down with my sword, and that's it."

Upon hearing this, Bronya's brows furrowed even tighter. She thought Ishiu was just unwilling to answer her question.

"Forget it, if you don't want to say, I won't force you," Bronya paused, looking at Ishiu with a complicated expression before continuing, "You... I know your reactions these past few days. I don't know if you've truly changed, but I hope it's true. Because you are the son of Patriarch Cocolia, and she has lost a lot for you. I don't want to see her suffer because of you again..."

"Alright, Little Pudding, I know what you mean. Just consider the old Qiye Ishiu dead. The current me is just Ishiu," Ishiu interrupted Bronya directly. He knew what she meant, and he certainly wouldn't be like that Qiye Ishiu, who did nothing but cause trouble all day.

He still needed to find a way back to his original world.

After speaking, Ishiu walked past a stunned Bronya and slowly left.

"Jerk! What did you just call Bronya?!" Bronya only reacted after Ishiu had left. Her small face turned red, and she was about to go find Ishiu in a fit of anger.

However, when she ran out, Ishiu was nowhere to be seen. She could only curse a few times before returning dejectedly.

A few days later, in the morning, as Ishiu walked out of his room, he immediately felt the heavy atmosphere in the Qiye Family. Everyone wore solemn expressions, as if something bad was about to happen.

Ishiu wanted to ask someone for the reason, but due to his special identity, everyone avoided him, which gave him a headache.

It wasn't until Cocolia summoned everyone to the family hall for a meeting that Ishiu finally understood why the atmosphere was like this today.

It turned out that the Qiye Family had detected a gathering of Honkai Beasts near the town, advancing in their direction. Based on their speed, they would arrive by noon today.

Cocolia gravely analyzed the number and types of attacking Honkai Beasts. Everyone's expression was grim because the number of attacking Honkai Beasts was the largest in recent decades.

If not handled properly, it could lead to complete annihilation, the fall of the town, and millions of lives being trampled by the Honkai Beasts.

As the leader, Cocolia quickly issued orders to the various combat and logistics teams. The entire Qiye Family was mobilized due to this Honkai surge.

The only ones not assigned a mission were the elders of the Qiye Family, children under ten, and... Ishiu.

After Cocolia's orders were issued, everyone busied themselves, preparing weapons, inspecting mechs, and so on. Everyone's emotions were stirred.

After all, this battle concerned the lives of millions and their homes. No one could be indifferent.

(PS: Some say Chariot-class Honkai Beasts aren't that tall, but here we are using the setting from the manga and exaggerating it a bit. After all, a Honkai Beast isn't necessarily stronger just because it's taller.)

Chapter Twenty-Eight: System Mission Issued

"Mom, I want to go to the front lines too."

"Ishiu, don't cause trouble for me. Just stay home and wait for your mother's triumphant return with good news, okay?"

"No, I can help. I promise I won't be a burden."

"Ishiu! Can't you just listen to your mother? Do you know how dangerous the front lines are? Do you want to make me lose sleep for several nights like last time?"

"..."

The above is the dialogue from Ishiu's attempt to join the battle, which was rejected by Cocolia.

He really wanted to say that he was no longer the useless Ishiu he used to be, but he didn't know how to express it. Cocolia's concern for him was undeniable, so she would absolutely not send him to the battlefield. She was even prepared to have Ishiu evacuate with the children. If they were overrun, these remaining children and elders would be the last hope of the Qiye Family.

Ishiu felt both speechless and a little touched by this.

So, in the end, he decided to observe the situation first. If things went wrong, he would act then. Although one person's strength might not make a significant difference in the war, he still wanted to do something, at least... to protect Cocolia and Little Pudding.

Although he didn't feel a strong connection to the people in this world, just for Cocolia and Bronya's sake, even knowing they weren't the same as the two people in his memory, he still didn't want to see them get hurt.

Thus, Ishiu was left alone at home, while Cocolia led the great army of the Qiye Family, armed with weapons and mechs, to meet the Honkai Beasts.

Ishiu wasn't idle either. He went to the Qiye Family's control room, where the logistics and research personnel who couldn't fight were gathered. They were closely monitoring the battlefield situation and ensuring timely communication with Cocolia's forces.

The battle between the Qiye Family and the Honkai Beasts was imminent.

Upon meeting, neither side hesitated and immediately engaged in a fierce fight.

This was the first time Ishiu had truly witnessed a battle between humans and Honkai Beasts. Looking at the vast, dense horde of Honkai Beasts, like an endless tide, he felt ashamed of the pride he had felt after easily defeating the Ballista-class Honkai Beast.

Indeed, the reason Honkai posed such a great threat to humanity was never determined by the strength of one or two Honkai Beasts.

You could defeat one Honkai Beast, or ten, but could you defeat a hundred, a thousand, or even tens of thousands?

Moreover, Honkai invasions brought not only Honkai Beasts but also infected Zombies and environmental changes.

Expelling Honkai was not an easy task. Ishiu once again deeply understood this fact.

Regardless of Ishiu's thoughts, the battle on the battlefield would not change.

Although the Honkai Beast army was numerous, the mechs dispatched by Cocolia were not to be trifled with. These mechs were unmanned and possessed extremely high combat capabilities. Even if destroyed, there was no need to worry about casualties.

Combined with the suppressive fire from the Seven Nights clan members, the battlefield was currently in a tentative stalemate.

Everyone in the control room watched the great battle on the screen with extreme tension, desperately praying for victory. Just then, a buzzing alarm suddenly sounded.

"Oh, no! A group of Honkai Beasts has appeared in the southwest and is heading towards the town!" a female researcher exclaimed.

"What?!" Everyone was shocked. "Why wasn't it detected earlier?!"

"They were traveling by water, and the Honkai Energy detector in that direction had some malfunctions. They were only discovered after they landed."

"Th-then what should we do? Cocolia-sama has already taken everyone to the front lines. Even if we redeploy forces now, it will be too late!"

The people in the control room were in chaos, unsure of what to do. Cocolia, upon receiving the news, also dispatched a squad to quickly return for defense. However, they were too far away; by the time they returned, the Honkai Beasts would have likely already broken into the town.

"Don't panic, I'll stop those Honkai Beasts." Just as everyone was at a loss, Ishiu's voice echoed in the control room, his calm tone reaching everyone's ears clearly.

"You?" Everyone looked at Ishiu in surprise, who remained composed.

"How many Honkai Beasts are there?" Ishiu ignored their strange gazes and directly asked the female researcher.

"T-There are seventeen in total. One Chariot-class Honkai Beast, three Ballista-class, five Knight-class, and eight Rush-class," the female researcher answered instinctively.

"OK, leave it to me." Ishiu nodded, then turned to leave.

"Wait! What do you think you're doing? Going there with your strength is just suicide! I won't let you go!" An old man with white hair and a white beard blocked Ishiu's path, looking at him with a serious expression.

Although Ishiu had a bad reputation within the Qiye Family, he was Cocolia's son. As members of the Seven Nights clan, they could look down on Ishiu, but they absolutely could not stand by and watch him die!

"Don't worry, I never do anything I'm not sure of." Ishiu smiled slightly, placing a hand on the old man's shoulder. Then, everyone felt a blur before their eyes. The old man who had been blocking Ishiu was now standing ten meters behind him.

"Alright, just wait for my good news." Ishiu waved his hand, glanced at the old man whose expression was filled with surprise and uncertainty, and the group of Qiye clan members who looked somewhat disbelieving, then turned and walked out the door.

"..." Everyone fell silent. They didn't know what this young master, whom everyone considered useless, was planning to do, but Ishiu's previous display had indeed shocked them.

Just as everyone was still trying to process what had happened, Ishiu's figure reappeared at the entrance. He had returned.

Ishiu scratched his cheek a little sheepishly and said in a low voice, "Uh... could one of you give me a map?"

After obtaining the map, Ishiu ran straight out of the town. At the same time, he received a mission from the system.

[Ding! System has issued a mission: Help the Qiye Family prevent the Honkai Beast invasion. Mission reward is unknown.]

Although he didn't know what kind of reward this scamming system would give him this time, based on past experience, he had received a great prize like the complete version of the Seven Nights Assassination Technique last time. This time, it would probably be something like a candy handkerchief, or if it was even more of a scam, maybe even a girl's used underwear.

Chapter Twenty-Nine: Slaughter

After running out of the town, Ishiu headed in the direction indicated on the map. The Honkai Beasts were indeed very close to the town. He had run for less than ten minutes before he saw the shadows of the Honkai Beasts.

"Hiss—As expected, they're as exaggerated in size as ever."

Looking at the Chariot-class Honkai Beast, which was thirty meters tall, Ishiu felt a bit of a headache.

"Young Master Ishiu, if you can't handle it, it's still not too late to retreat. We've already started evacuating the town's residents," came the voice of the female researcher through the headset. Through the drones, they could also see the Honkai Beasts.

"It's fine, I can handle it."

Ishiu tightened his grip on the Plasma Katana, glanced at the Chariot-class Honkai Beast, and then set his sights on the other Honkai Beasts.

There was no other way; he couldn't deal with that big guy right now, so he had to take care of the smaller ones first.

At this moment, the group of Honkai Beasts also spotted Ishiu and let out roars that signaled an attack.

"Young Master Ishiu, be careful! They've found you!"

Following the female researcher's panicked cry, a massive fireball flew directly towards Ishiu. It was a Ballista-class Honkai Beast that had initiated the attack.

The fireball was incredibly fast. At a distance of one hundred meters, it reached Ishiu in less than a second.

Watching this scene, the people in the control room collectively closed their eyes, their hearts heavy.

In their eyes, Ishiu was bound to be annihilated in this attack.

However, a few seconds passed. The control room, which had been silent, suddenly erupted with a joyous shout.

"Y-Young Master Ishiu isn't dead! He's not dead yet! He's still attacking! He's still attacking!"

Upon hearing this, everyone opened their eyes and looked at the big screen.

Indeed, at the spot where the fireball had exploded, Ishiu's figure appeared thirty meters away. Not only was he not dead, but he hadn't even sustained a scratch.

"H-How is this possible..." Everyone was both surprised and confused. Then, their eyes widened, eager to see what Ishiu would do next after surviving.

Unaware that he had become the star of a live broadcast, Ishiu easily dodged the fireball attack and charged towards the pack of Honkai Beasts.

This was his first real battle against Honkai Beasts. It was different from the training room; the atmosphere and the smell of the battlefield were things the training room couldn't replicate.

But unexpectedly, his heart was calm, so calm that he found it strange himself.

It was as if... these Honkai Beasts couldn't even stir his fighting spirit.

It was like humans wouldn't be provoked by the challenges of ants.

Although it felt a bit arrogant to say so, Ishiu truly thought this, and he acted accordingly.

'Clang—!'

'Pfft—Pfft—Pfft—!!!'

Sword light flashed, and amidst sounds like tearing silk, Ishiu's figure flickered rapidly within the Honkai Beast horde.

He was like a merciless god of death; every appearance, every strike, was guaranteed to claim a soul.

The Honkai Beasts roared in anger, but they were powerless against Ishiu. A Knight-class Honkai Beast had just raised its spear, but in the next second, the man who had been in front of it had silently appeared behind it, and its head fell off.

[Flash Sheath - Four Ghosts Annihilation!]

A sharp cross-shaped blade light flashed, and a Ballista-class Honkai Beast was instantly cut into four neat pieces, losing its life and dissipating into pure Honkai Energy.

[Flash Sheath - Six Realms Unfettered Tribulation]

The white ribbon transformed into six slashes in an instant, striking the six Rush-class Honkai Beasts simultaneously. Before they could even let out a whimper, their heads were severed.

Ishiu was like Death himself wielding a scythe; no Honkai Beast could survive a single round against him, nor could they even muster the slightest resistance.

During this process, Ishiu's mastery of Flash Sheath and Flash Walk grew even more profound.

The Seven Nights Assassination Technique was inherently a killing art. Without truly tasting blood, no matter how long one trained and studied, they could never grasp the true power of this technique.

Every move seemed to come alive in his hands, executed with effortless grace. By the time Ishiu stopped, only the Chariot-class Honkai Beast remained on the field.

"My performance wasn't perfect this time."

Ishiu exhaled a breath of stale air, his gaze sharp as he fixed it on the Chariot-class Honkai Beast. If the previous battle was just a warm-up, then the real show was about to begin.

Meanwhile, in the control room, everyone was stunned after witnessing Ishiu's massacre.

Their eyes widened in unison, mouths agape. Some even doubted if they were dreaming, pinching their thighs.

But no matter how hard they pinched, the intense pain assured them it wasn't a dream. Ishiu had single-handedly annihilated sixteen Honkai Beasts, and it had been a one-sided slaughter.

"Is... is this the legendary Seven Nights Assassination Technique of our Qiye Family?" someone exclaimed in shock, having grasped something from Ishiu's movements.

The entire control room erupted into chaos at his words.

However, someone intervened to quell the disorder. Cocolia's voice came through the communication channel.

"How are things on your end? My dispatched team will arrive in ten minutes. Have the Honkai Beasts entered the city yet?"

"C-Clan Head Cocolia, the Honkai Beasts haven't entered the city. They've all been killed. Only one Chariot-class Honkai Beast remains."
