The Arc City, known for its reputation of being a giant, cybernetic city, under the protection of Schicksal and other mysterious faction hides underneath the shadows. Many people had come to this place, they sought for a shelter, people wanted to be protected from Honkai and the evil threatening their lives. Little did they know, that city's crime rates has gone up recently, the crimes, hides from the names of the people protecting this city, so that's why they wouldn't be noticed.

Illegal drug trades everywhere, fake Honkai resistance pills, fake passports being sold to people for some's own profit, until some garrison troops of Schicksal here has noticed it, the net of the crime organizations here has already connected and completed. People are dying slowly every day in debts, there were no hope for the people living here in this Arc City as Schicksal cannot do anything, because they have no spare time to deal with those things in this city. Jomungard cannot help them, because it is not their thing, besides, they are also a part of it.

All hope is lost as there are more and more people ignoring the poor lives in this city, until a white knight has arrived here. They took no mercy against the crimes of this place, show pity to the poor people begged them for help. To the people they have helped, they view the White Knight as a savior. Many people would have died if not because of them.

Eventually, something has to come, will come. Their name spread wide in the city, as an urban living legend. To kids, they were hero, and to adults, they were their biggest savior. However, to the crime organizations, they are just another obstacle on their road. A big one that they will take down.

It was in a raining evening, some thugs in the streets are beating up some old man because he cannot paid the debt. Some people were there, but they cannot help the poor old man. They just don't want to get in the trouble, that is the harsh reality, so they left, letting the thugs beating the old man.

"How long it will take for you to pay your debts!" – A young man, one of the thugs beating the old man, grabbed the old man's collar and shout to his face.

"P- Please spare me.. I have sold everything I could... Yet.." – The Old man begging the thugs to forgive him.

Too bad for him, if things like this can be solved with begging, then life wouldn't be so hard. The thugs' had it, they decided to kill the old man and trying to sell his organs, if, an old man's organs can worth money. Their souls has been rotten, by some papers.

A lighting strikes in the sky, the rain became heavier. The old man lays on his belly, on the ground, he looked over to the sidewalk, as one of the thugs taking out a handgun. He is begging for help. As if there are people here, staring at him.

As if god sent an angel to this corrupted city. The old man saw a person with the white hair on the sidewalk, walking towards them without hesitation, while their hand holding an umbrella.

Many rumors spreads in the city, saying the White Knight protecting them is a young girl. At first, the old man was one of those people believed it was a man, because a girl cannot be strong enough to fight crimes all by herself. Now he is crying, a part of regret, a part of grateful that the Knight has come to help.

She takes the umbrella in, grab one of the thugs' shoulder. He looks back, what awaits was the elbow of the girl sent right to his face. The girl broke his nose, alert his friends, when they all looked over to her, she was already on the move, taking down the thugs all one by one, with her bare hands, and her legs kicking them. Injuring them badly, but none of them died.

The old man lying on the ground, witnessed the actions he never thought he would get to see one day, with him, being the saved one.

The girl looked over to him, the old man sees she has two different eye colors, one side is orange, while one side is blue as the sky.

She was a strange person, her face, her eyes show no emotions. Even when one of the thugs standing up with a handgun on his hand. He wants revenge, by killing and ending the legend right here. The girl just reaches for her umbrella, for the hook handle. Points the umbrella to the man who is ready to kill her.

"Stop, you will regret." – The girl says, with a voice that don't express hate towards the man.

However, the man had been blind by his rage. He pulls the trigger, but it didn't hit the girl, the bullet missed the girl standing there. After that, while he is still wondering why it didn't hit, the girl's finger pulls a trigger on the hook handle of the umbrella. From where it was supposed to be the ferrule of an umbrella, it was a hollow pole inside, from inside of it, it shoots a bullet, send straight to the man's forehead, killed him.

The old man was surprised, he never heard of their savior killing people before. Now, he witnessed it with his own eyes, the man's body touches the ground lifelessly, along with the gun. He got killed, by an angel. The old man hear some police siren in the background. While he looks back to his savior, the white haired girl, with her umbrella gun was already gone. She vanished like a shadow, into the darkness of the night.

The cops arrived, and judging from the scene, they already know what happened here. Even the cops in this city, are not stupid and blinded by their own ego, they also view the White Knight as a hero. They wanted to help, they tried to reach the Knight for so many times, but never got a respond from them.

Mainly is because the White Knight only appears when the night falls, and no one has really seen her face clear before, even if they do, there is no way of retelling how she looks like exactly to the details, and a part is being no one knows how she dressed. But some people were glad of this, because the people she angered, might go after her with those details.

At an abandoning apartment near the border of the Arc City, is where our White Knight stay, or we will call her Kiana from now on, because she is Kiana in this world, but she had been through many terrible things. To the point she cannot smile anymore. She turns on the weak lights, and then sitting down on the stone floor, wrapping bandages around her arms, covering some small wounds she got from battles, it seems.

Beside her are some medical stuffs, she used to ease her pain and stop the Honkai infection from the Herrscher core from consuming her body. Beside her, was a picture of her taking with her friends, she looked at all of the people in the picture one by one, with a sad face.

Back in the scene, where there was a man killed by Kiana, the cops are still investigating around, and arresting the thugs for inflict violent on citizens and possessing dangerous firearms. They also carried the dead body away, while cleaning up the traces of murdering.

"Why do we do this? Isn't this backing up some murderer?" – A rookie cop asking his seniors.

His partner, who has been a cop longer than him looked over to the rookie, he show no negative emotion towards the rookie's question, but calmly explaining to him.

"Technically yes. But at least our Knight doesn't run around and kill people like those who she killed."

"Still a murderer."

"Well, say what you want. But we viewed them as hope for this rotten city."

"They are just some murderer! How could they be a hero for us?"

"Well. Sit down and think. You will understand it, someday. Especially for us. Her existence is really a matter." – The senior cop saying, while he just sat down on the police car's hood.

"Her? You know their-"

"Nope, not at all. Just hearing rumors." – The senior cop dodging the rookie's accession, while getting off the hood and get in the car. "Let's go back, everything is done here for us."

"How about that old man victim? We have to get some-"

"It's not necessary now, we will do it tomorrow. Now let's go back, it's late for everyone." – The senior cop starts the engine, and waiting for the rookie to get on the car.

When he gets on the car, it droves away slowly in the rain.

"Still. I don't get it, why we have to cover up for a murderer? I don't care if they saved people, there is nothing good on killing people." – The rookie still bragging that topic up. "She made us cop looked useless!"

"Well, here's the question that might help you to understand it." – The senior cop saying while driving the car. "If there is no such thing as the White Knight, how many innocent people would have died?"

"Well, that's why this city have a police department! We were established to stop those criminals! Not sitting around waiting for the signal of White Knight's appearance and come to clean their mess."

"Then why don't you do so? Gather up some people have the same goal like you in our unit. Or just bring me along, look if you dared to get into those thugs' business in the dark alleys."

The rookie let out a long sigh.

"Only if there is someone else in our unit have that same thinking..."

"There isn't. Because most of us at the beginning were just like you. We even tried to hunt them down. But the harder we tried, the more foolish we were. We realized we were letting our ego blind ourselves, tricking we into taking down the single light of hope that this city's people have wished for a long time."

"Or it was simply giving up because you guys didn't even tried that hard."

The senior cop let out a laugh, as he is laughing into the mindset of his partner.

"Oh... You will see that soon. If you want I could help you getting traces of the White Knight, but don't expect me to help you take them down."

"You're just supporting her, like the rest. Your mindset are all ruined beyond salvation, you guys are not worth to be the protectors of the city."

The rookie is now being rude, not respecting his senior, he is just ranting about why the cops have to go against their rules and helping a murderer. But the senior did not get mad at him, all he did is just laughing. Because he know one day, his rookie partner will understand why. All of a sudden, the sound of someone contacting them through the radio set broke the atmosphere of the senior's laughing and the rookie's rant.

"All cops in sector E-2, there is a robbing case at a convenient store on the Schraion street, two suspects with firearms. 3 held hostage."

The communicating channel just provided them information a robbery case.

"Schraion street. We just ran pass it." – The rookie saying, and looking back.

"Hold on." – The senior car then drift the car without stopping, after making sure the road it empty. And then drove forward to that street.

At the store, 2 normal citizen got tied up with tapes, and the store's staff just got tied up as well, a robber pushes him to sit down next to the other two hostages.

"Hen, we're rich." – The robber standing at the cash register, taking out bunch of money. "As expected from looting a store before it is closed."

"Shit, why did you say my name?"

"What? Shit I forgot, sorry. But who's gonna get us anyways?"
"I don't know man, it's midnight, The White Knight could come for us."

"Ah, they could come here. But they will die." – The robber said as he put his handgun on the table, while putting the money in a bag. "Anyways come here and help me."

"As if you can take down them with a gun. Heard about Richard? He got killed earlier by them."

When they were talking, they can see the police siren, getting closer to the store after every second.

"Shit, it's the cops." – The robber holding the bag with money, use his other free hand reaches for the handgun. "How did they-"

He noticed a camera on the ceiling, in the corner. It seems the robber made a heist without noticing that camera so far, which led to the cops to come here sooner than they expected. He shoot the camera then running to the door in the back of the store. As the cops just arrived there and armed with guns.

"No sign of the armed robbers!" – The rookie cop saying.

"They must have ran away as they heard us, they're in the back, you take care of the hostages, I will deal with the robbers!" – The senior cop saying, as he drawing out his pistol, checking the bullets in the magazine, then rushes to the back.

Meanwhile at the back, the robbers just burst open the door, and running away in the dark alley as they heard footstep approaching them. While they are running, from a small alley in the corner of their eyes, a shadow launches out of it, and went away into the opposite alley with a robber, the one with the money. The other robber shocked and dropped his handgun, he looks into the corner, it was too dark, he can't see.

Yet, he can hear the sound of someone punching something hard. It is no doubt that his friend got punched so hard by someone in that alley right now. Without thinking much, he decided to pick his gun up from the pond of water under his feet. Another lighting struck in the skies, the robber while looking down the gun sees a reflection on the water. In front of him is someone standing there now. He was afraid, yet picking up the gun. The moment he picked the gun up a foot stomped on his hand, prevent it from picking the gun on. Next, a knee was sent to his jaw forcefully, making him passed out.

Yet the mysterious person attacked the robbers did not stop, as the robber falls down on the water, his collar got grabbed, and the person keep punching at them, until the senior cop from earlier came there with a flashlight and a gun.

"Stop right there! Get up and put both hands after your head!" He shout as he sees there is someone beating a person down to the ground badly, even he can see blood slowly mixing into the pond of water from the rain.

The person ran away immediately, the cop did not shoot at him, because he did not expected such thing to happen, moreover, he came to the robbers on the ground, all got beaten up badly. The rookie cop just came after for the senior cop, he came and see this thing. More police sirens can be heard in the background.

"What happened here? Was it the Knight again? Did you saw them?"

The rookie asking his senior, who was observing the case carefully.

"No, it's not. It's not our knight..." – The senior cop then stand up slowly, looking at where this mysterious person ran off to. "Someone else..."

The mysterious person running across many different blocks, and he has no sign of stopping, he take a look around before stopping in front of a dumpster, then climbing up on top of it, slowly parkour up to the surface floor of a building, the rain has stopped, but the sky is still growling in the background with some thunder.

The person stops on that building, catching his breath. Noticing a footstep approaching them from behind, he takes them time turning back slowly. In front of him, is someone that they have been mistaken of. The White Knight is standing there, putting their umbrella to their back. 

End of Nightfall Umbrella Part 1.
