The everlasting link of light

Thanks to the strenuous fighting of Cosam and other thirteen knights, the invading fleet was soon completely expelled, and Cosam and others naturally enjoyed a grand triumphal ceremony as heroes without any surprise.

However, victory is only temporary, and peace is only a temporary truce. A defeat did not make the invaders realize their mistakes, but instead they began to prepare for the next attack.

So in order to solve this problem once and for all, the elders of Pis Star, after intense discussions, had to make a decision that would change the fate of countless lives.

"Cosam, after unanimous discussion among the elders, it has been decided that... the restart plan has officially begun."

"really?"

"Ah."

The chief nodded solemnly, and it was obvious that he was one of the few people who opposed this plan.

After hearing the news, the young Kosam's face was filled with indescribable confusion.

After his expression changed, Kosam tried, "Chief, can you please try again? The invaders are hateful, but there must be many kind-hearted people who love peace on that planet. Such behavior is simply a massacre! Then there is no difference between us and the invaders!"

"I'm sorry Cosam, I understand your thoughts, but... the situation has gotten out of control, everyone has lost their minds, and now they only think about revenge."

The chief shook his head somewhat dejectedly, and then began to look up and down at the device on Kosam. After a moment, the chief suddenly muttered to himself: "I seem to have made an unforgivable mistake."

"Ok?"

Just when Kosam was about to ask further questions, the chief turned around and left without looking back.

夜晚

Kosam, with a heavy heart, returned to his residence.

"Brother, you are back."

"Yuuyi~"

Seeing his lovely sister coming over, Kosam, who was originally in a bad mood, instantly felt much better.

Placing his hands on his sister's shoulders, Kosam smiled and said, "How's it going, Yui? What did you create today?"

"Of course, brother, look."

As soon as she finished speaking, Yui smiled and took out a painting from behind her and handed it to Kosam.

Yui introduced with a smile on her face: "I designed thirteen powerful knights based on you brothers. I plan to add some enemies later, which will highlight your bravery."

"Well, thank you, Yui."

Upon learning that his sister was so devoted to him, the smile on Kosam's face deepened.

"It's nothing. After all, you brothers are heroes who uphold peace and justice."

"Forehead?"

Hearing Yui's words, the smile on Kosam's face froze, and there was a hint of doubt in his eyes.

"Hero?"

Seeing Kosam's reaction, Yui asked in confusion: "Brother, what's wrong with you? Why do you look a little depressed?"

"It's okay! I'm just... really tired today. I'm going to rest first!"

"elder brother!"

Not wanting to discuss the matter any further with Yui, Kosam hurried back to his room and locked the door.

"Hero? What I'm going to do next... am I still worthy of this name?"

Kosam leaned against the door and asked the question in a muttered tone.

The next day, the action was officially implemented!

Thirteen people led by Kosam broke through the numerous defenses and placed the newly developed planet-destroying bomb on the invaders' home planet. After a loud earth-shaking noise, all living things on the surface of the planet met their end ahead of schedule.

The crisis of invasion finally ended, but a new crisis emerged.

Because they had planet-destroying bombs and powerful fighters like Kosam, some high-ranking officials began to get restless.

"Mass-produce planet-destroying bombs immediately!"

"Since our kindness has received such a response, we must teach those people a lesson!"

"Times have changed! Those old days are gone forever!"

Although a considerable number of people expressed opposition to such a plan, in the face of the army and weapons of the pro-war faction, these people physically lost the qualifications to express their opinions, including the chief who developed the enhancement device.

At the same time, the war advocates, who had been dazzled by the results of the war, took control of public opinion and called this action a just war of revenge. All the planets that had not helped Pise for various reasons were recorded in the list of planets where planet-destroying bombs were placed.

The lower-class people who did not understand the inside story were completely controlled by public opinion and strongly supported the decision of the top leaders.

Although Kosam and others expressed strong protest, they were powerless to twist the excavator, so they could only grit their teeth and carry out this series of tasks.

Unknowingly, they went from being heroes protecting their homeland from invasion to becoming tools for the higher-ups to realize their ambitions.

"Yuu, I'm back."

After razing the surface of another planet, Kosam dragged his tired body back home. However, after shouting out his habitual mantra, Yui did not appear in front of him as usual.

"Yuuyi?"

Seeing this abnormal scene, Kosam's heart skipped a beat, and then he walked quickly to look for his sister.

"Yui where are you? Yui!"

While shouting, Cosam came to Yui's room. When he pushed open the door, the scene that came into his eyes made Cosam's pupils shrink instantly.

I saw Yui lying on the bed like Sleeping Beauty, but blood was constantly flowing from her right wrist.

"Yuyi!"

Kosam rushed forward like a madman and hugged Yui's already cold body in his arms, calling his sister's name over and over.

But it's too late.

"Yuuji, why are you..."

Just when Cosam's sanity almost completely collapsed, he accidentally caught a glimpse of a note on the bedside with a line of words written on it.

[Stop it, brother. Don't make any more mistakes. Once you take an innocent life, you will never be able to turn back.]

"Yui... why are you so stupid!"

Holding Yui's cold body tightly in his arms, Kosam shed tears for the first time in his life.

This kind and sensible girl is a rare person who can maintain her sanity, but being awake in the midst of chaos is an unforgivable sin!

So, Yui finally chose to use her own life to wake Cosam up.

But what Yui never expected was that her actions actually made Kosam sober up, but it had the opposite effect.
