Guilty Crown: The Lost Kingdoms: Gaiden

Side-Mission: Brotherly Care

Funeral Parlor Headquarters/Atrium/November 3rd, 2022

(Cue Guilty Crown – Alpha (3:02 onwards))

It was another afternoon for the notorious Undertakers to have a mission. Most of the people are gathered in the usual atrium. Shu and Inori are nowhere to be seen for today. Gai is standing on the top mini-floor announcing his thing like the usual boss he is.

"Okay people, we have another simple mission in our hands. So let's make it count!"

Typically, every one of his followers cheers at this statement such as Ayase, Tsugumi and Argo. It seems pretty decent to deal with. Except there's one thing, someone seems to be missing, as one magical girl points out.

"Say, where is Kyoko?" Sayaka looks around.

"Hey, now that you mention it, Sayaka." Madoka said with concern. Homura remains silent for the matter.

Mami then realizes, "Wait girls, I remember yesterday that she did a midnight snack that she-!"

(End Theme)

Just then, they hear a loud groan coming from behind. Everyone turned to see a familiar, red-haired magical girl walking slowly. Yes, that is Kyoko Sakura. The girl is seen in her teal pajamas, her eyes are looking fatigue, and she places her left hand on her stomach.

"Kyoko, you're sick!" Madoka cries out in worry.

"Seriously, you just ate too much food that night for some stomach flu?!" Sayaka chastised at her friend.

Kyoko said nothing from her friends' concern. Her stomach rumbles again that she groans.

Then, Gai sighs and turns to Shibungi, "She has to stay here to feel better. We can't waste anymore time."

"I agreed." Shibungi replied. "But someone should take care of her as well."

Now that his second-in-command said that, Gai has a wonderful idea in the last minute.

"I believe I have the right guy to do this." Gai smirks as he then faces someone he sees.

Argo takes notice at the blond-haired leader looking at him and said in surprise, "What, me?!"

"Yeah, you two have quite it common pairing up recently. Stay here to make sure she's better." Gai ordered the spiky-haired mercenary.

"Oh come on!" Argo cries out to his boss. "How can I suppose to handle this kid?!"

"Well, do something yourself, that's all." Gai could care less of Argo's complaint before turning to the others. "The rest of you, lets get going to that mission."

With that being ordered, Gai, Shibungi, Ayase, Oogumo, Madoka, Sayaka, and Mami are going to leave the area.

"Good luck." Oogumo stated to Argo before leaving.

"Let's hope that girl doesn't bite." Shibungi sarcastically joked before he left.

"Feel better, Kyoko!" Madoka smiled.

Sayaka said to Homura, "Just keep an eye out, will you?"

"I will." Homura nodded.

Gai and his mini squad then leave the Atrium. Argo, Kyoko, Homura, Tsugumi, and Kenji remain in the area.

Argo looks around in disbelief. Normally, he is excited in wanting to take part of missions, now he is forced to babysit a sick magical girl. Homura simply stands there emotionless, while Tsugumi and Kenji ignore Argo as they are busy in their usual spots to contact their team.

Feeling so grumpy that he's staying in the hideout, Argo walks towards Kyoko.

The red-haired magical girl slowly looks up at Argo. She glares at him and mutters, "What are you looking at?"

Argo replied, "Look, your sick, and I have to take care of you."

Kyoko doesn't seem to like it. She growls like a rebellious animal only that her stomachache hurts her again.

"You have a problem, kid?" Argo berates her. "You can't go outside like this, so I'll just have to take you to your room!"

After the mercenary said that, he picks up Kyoko unafraid and is going to leave the atrium. Kyoko cries out in anger and attempts to free herself, but remains sick to do so.

Homura watches them leave and stated, "Perhaps I can help, I'll be heading to the kitchen to make something for her to feel better."

"Thanks a lot." Argo sarcastically replied due to holding down the rough Kyoko in his arms. They then leave while Homura walks to the kitchen area.

Funeral Parlor Headquarters/Kyoko's Room

A kick suddenly barge in the door to Kyoko Sakura's room. This small room has a bed, and it looks messy littered with clothes and other things.

Argo looks at the surroundings and muttered, "Geez, your room is a mess."

"So what, I'm fine the way it was!" Kyoko rebukes.

"Still, you're heading to bed." Argo chastised at the rebellious magical girl as he place Kyoko to bed and quickly covers her in a blanket and a comfy pillow. "And you are staying right here, kid."

Kyoko is upset and groan of the treatment, as if not taking part of the mission is enough for her.

"Damn, who put you in charge as nanny?!" the red-haired magical girl shouts.

"Hey, I'm not some nanny!" Argo retorts back at her with his arms cross. "I'm doing this because Gai said so!"

"Well, I wanna take part of a mission, and no one's gonna stop me!" Kyoko growled.

"Whatever, since you're sick, you can't seriously going to hurt me, skank." Argo taunted.

"OH YOU ARE SO FUCKING-!" Kyoko anger rises further from that insult and her hands are about to reach Argo, till her stomach pain makes her feel hurt. The magical girl defiantly glares at Argo for a moment before her fiery anger begins to subside.

Tensions begin to calm down as the mercenary watches Kyoko calming down and laying her head on the pillow.

"Here." Argo throws something digital on the blanket for the sick girl. "It's a visual set, you can watch anything such as the news, music, whatever works for you."

Kyoko gets the visual set and observes at it like a curious child before turning it on to show a diagram. It seems easy to use.

Argo begins to walk away saying, "I'm going to head to the kitchen. Homura is having the people making some healthy food. You stay put and behave yourself."

Kyoko didn't say anything despite her initial hostility of not feeling so good. The girl watches as Argo leaves her room.

Funeral Parlor Headquarters/Kitchen

(Cue Madoka Magica Portable OST – Tutela-Materia Homurae-)

Minutes later, Argo arrives at a huge kitchen with a bored look on his face and his hands are in his pockets. The kitchen is shown to be something from a restaurant, filled with cooks, dishwashers, and other staff that help out the place.

As Argo walks around the place, he notices Homura convincing some helpers to cook up a special treatment.

The mercenary walks towards the raven-haired girl and asked, "What did you tell them to make."

The stoic Homura answers, "It's a kind of healthy soup to help a person's immune system."

"You mean like chicken soup?" Argo quipped.

"Maybe in a way." Homura replied, "Although we normal get sick by common means, magical girls can get better in a day or two due to their support abilities are different compare to others."

"Heh, I get it."

"Has Kyoko Sakura treating you well?" Homura asked about her comrade's condition.

"As if, she gets so pissed of being sick." Argo felt annoyed. "Hell, it's her fault she went through that midnight snack."

"I know her well, she does have rebellious problems, but it takes time to make her understand." Homura stated. "Perhaps you and her can discuss something related."

"Thanks for the tip, I guess." Argo replied in unsure what Homura is really telling.

"The food will be served in about a few minutes, so please wait outside."

"Ok, then." Argo nodded, in which he walks to leave the kitchen.

10-12 Minutes Later

Exactly what the minutes are saying, the healthy soup that the kitchen serves is ready for Kyoko Sakura. A bowl with that food appears on top of a wheeled tray, alongside a soup and some napkins. Both Argo and Homura are seen in the hallways.

"The soup is finish." Homura announces before thought about one more thing, "And here is something the place has for medicine afterwards."

The calm magical girl gives Argo a pink soothe medicine for stomach reliever alongside a Poland Spring water bottle.

"Thanks again for the help." Argo nodded as he place the medicine and water bottle in the tray. "Now I gotta head back to her room. God hopes she doesn't get in trouble."

Homura firmly nods as she watches Argo moving the cart to head his destination to the sick magical girl's room.

Funeral Parlor Headquarters/Kyoko's Room

Later, Argo arrives back to the feisty magical girl's room. He has the wheeled tray with the remedies moving towards Kyoko's bedside. Argo then hears a familiar song that the sick magical girl plays in the mini visual set. True to his word, Kyoko seems to behave decent.

He walks closer to Kyoko's side and sees an old music video of Psy's Gangnam Style. Yes, Kyoko just found and watch the video of the Korean music star dancing like a fool, with random people, on the elevator, and with the horses.

"What the hell is that Gangnam Style?" Argo briefly changes the subject. "That is like ten years old now."

"Yeah, but the song is still catchy." Kyoko quipped.

Argo still watches the video a bit before saying, "Anyway, your soup is here."

The young man presents Kyoko the bowl of soup that will make the magical girl feel better. Kyoko stares at the bowl in curiosity.

"Does that make me feel any better?" The red-headed girl asked.

"Yeah, so you have to eat it. It's healthy unlike the food you ate last night." Argo stated.

At first, Kyoko is silent and unsure of trusting Argo's convincing. After a few seconds, the girl begins to comply and she begins to open her mouth while putting down the visual set. Argo sigh that he first sits on the bed, so that he uses the spoon for the soup and has it enter Kyoko's mouth. The magical girl feels the wonderful taste of the soup, in which it suddenly begins to sooth her stomach and appetite.

Kyoko beg Argo for more soup by opening her mouth. The young mercenary silently does so as he use the spoon to calmly make Kyoko eat parts of the food. This goes on for minutes until the bowl is almost empty. Surely that the magical girl is a big eater, but it is a nice change to control her usual habits. Afterwards, Kyoko takes her medicine by spoon alongside water, and is seen lying in bed peacefully.

"There, I hope the soup taste good for you." Argo said while he's still sitting after he finishes his task.

Kyoko softly smirks and replied, "Yeah..it's not that bad after all."

Both people stay silent for a brief moment, it seems Homura is right for the matter that it does take time for Argo and Kyoko to understand each other, knowing that both did not participate in today's mission.

Then, Argo says something serious to the girl, "You know, you once reminded me of my dead, younger sister."

(Cue Puella Magi Madoka Magica – Confessio)

The red-haired magical girl took notice of the compliment as her red eyes widened.

"Really, but I don't know where your getting at." Kyoko pondered.

Argo sighs a bit before explaining something important and gives a gloomy expression, "Let me tell you my story, kid. When I was young, I had the usual life with my parents and all. Heh, I was pretty much a headstrong kid who is looking out for my sister. She seems to be happy and full of herself. It is until that day, ten years ago with Lost Christmas. Those purple crystals suddenly appear out of nowhere and killing all these victims. I became shocked that my parents and my sister are engulfed by the outbreak in my own eyes. I can't save them. Afterwards, I was a survivor being traumatized, and currently settled with my generous aunt and uncle. As you remember hearing, I am a student of Ryusen High with decent grades, but nothing is the same."

"That's why you joined the resistance, I see about that." Kyoko interrupted.

"Yeah, I see Gai as that idol that is sworn to protect Japan from GHQ's regime. He is that guy that bestows freedom and the right to think ourselves for survival. My aunt and uncle are already aware of my double-life, at first they were worried about my safety, but they understand my choice to help Funeral Parlor. I don't know what to do afterwards, should I go to college or the military force.."

Another brief silence occur between the two. It is well-thought off for someone's own perspective.

Now it is Kyoko's turn to talk. She begins to speak with a serious tone, coming from the usual sarcastic attitude, "Now that I get it, I'll tell you my past in my home dimension. I had a younger sister too."

Argo is surprise of what she just said. The word 'sister' does ring a bell as Kyoko continues explaining.

"My dad was a preacher in a church, but nobody would care about his beliefs and all that crap. My family became poor as a result and I just wish anyone should listen to my dad's words. God, I wonder why people having some college degree of religious studies deserve this fate. That is when I made a deal with that fuzzball, Kyubey, to become a magical girl, in which my wish is to have people admire my dad again. Everyone listens to the church while on the other side, I fought Witches and Wraiths in believing that idealism can change the world. But then, it got worse. My dad found out that the reason people came back to his church was because of magic and not true belief. He went nuts and kills himself alongside my mom and young sister. I was left alive, nearly homeless for the moment."

After the magical girl let out her feelings about her tragic backstory, Argo could not believe what she was going through.

"And that at one point, being a magical girl urges me to look out for myself, for being selfish in a world full of grays. However, I slowly reconsider myself when I team up with other magical girls to defend our town, especially with Sayaka. Here I am now helping your butts in."

Afterwards, there is once again silence. Both have some form of darkness and yet endure them in their pasts. It is another reason why Argo is reminded of his 'darkness' when Shu used his void back in the mock test. Kyoko may be the most vicious out of all the holy quintet, but does have a broken aspect inside.

Then, Argo calmly places his hand to Kyoko's right shoulder, to which the young girl looks at him.

"I think we have something in common here." Argo forms an acceptable smile. This simple statement illustrates that their bond becomes better and start seeing each other as siblings.

Then, Argo's communicator is ringing, in which the mercenary senses this and stands up.

"I bet Gai's team is coming back home, they seem to miss you." Argo said to Kyoko. "Just want you to get some rest and feel better for tomorrow."

With a soft side coming from him, Kyoko forms a smile and nods, "Thanks, goodnight."

Which then, Argo Tsukishima begins to walk away. As soon as her 'older brother figure' leaves the room, Kyoko Sakura slowly begin to close her dark red eyes and rethink about her position. Trust from a normal human can surely make a sibling bond for the notorious vitriolic pair.

A/N: This may be one of the shortest sidestories I written. However, I enjoy writing the focus between Argo and Kyoko's relationship despite their arguments. There is the fact that both share each other's life stories to connect their bond such as the late sisters they had.

Review and take care.
