Okay this is my first Big Hero 6 fanfic, the setting is approximately 3 years after the movie and the first of two stories that will also incorporate the other four other members of Big Hero 6 as found in the original Marvel's comic. This one will incorporate The Silver and Ebon Samurai, with a few liberties taken.
Please note there are a few insulting terms used, these don't reflect my opinion in the slightest, but the point of view of the character that uses them. I apologize in advance for any and all offenses perceived.
The Magnificent Samurai
Introduction: The Tale of The Silver Samurai and Ebon Samurai
"Alright, Hiro, time for bed little man. Tadashi, it's story time," Maemi Takachiho [1] said as she picked up her three year old son, Hiro, and carried him to his bed.
"I'm eight years old, Okasa [2], I don't need a story. And it's the same story every night," Tadashi whined as he got into his bed.
"Well how about you tell it then, Mr. I've Hear It All Before?" His father, Tomeo Takachiho, chuckled as he took his seat.
"Well... ah..um... A long time ago at the base of Mt. Fuji... no it was Mt... Fine, Otosan [3]," Tadashi says in defeat. He crossed his arms over his thin chest and pouted at his father.
Tomeo laughed, remembering his own childhood. "Oh my son, I was just like you when I was your age. You see no matter how many times you hear a story, you don't remember everything. I'll let you in on a little secret." Tadashi leaned forward, excitement blooming on his face. "I read it from the book."
Tadashi frowned. "A book?"
"Occum's Razor, my son. The simplest solution is often the best." Tomeo says showing Tadashi the book.
Unamused by her husband's actions, Maemi scoffed. "Unbelievable, To-kun, you are just unbelievable."
"Oh come on, Ma-chan, my father was much worse."
Maemi scowled at Tomeo before turning to her impatient son. "Alright Tadashi, you get to read it from now on," she said as Tomeo hands the book to Tadashi.
Tadashi grinned as he accepted the book and opened it to the first page. He attempted to pronounce the bigger words, a small crease forming above his brow. "Long ago in a valley a day's walk from E-Edo…" He looked up at his father. "Edo? Doesn't he mean Tokyo?" he asked.
"Well Tokyo use to be Edo when the story was written and it didn't really become Tokyo until the Tokugawa shogunate, however the oldest part of Tokyo is still known locally as Edo. Now go on, son. You shouldn't string Hiro along for too long," Tomeo said, giving a little history lesson
Tadashi returned his attention to the book and resumed reading. "A humble farmer was gifted with twin sons, one's skin silver like starlight, Kenuichio, the other's skin like the wood of the ebony tree, Kioshi. Unlike their siblings, whom were suited for the country life like their father, the brothers had talent for combat which increased as they grew older," he read.
Hiro stifled a yawn with his hand and pulled his blanket over himself as his brother read on.
"One day the local daimyo saw these two practicing in the field and asked their father if he could recruit them for his retinue. Reluctantly the farmer consented, and the brothers then spent the next decade training and honing their skills. Day after day they pushed themselves and each other, mastering every weapon and almost every style of combat known in Japan. The skill of these brothers brought the attention of the warrior god, Takemikazuchi-no-kami, who demanded that they join his retinue in his clash with the rogue star god, Mikaboshi."
"The daimyo did not deny the god this request for to do so would increase the time Takemikazuchi-no-kami was not restraining the giant catfish, Namazu. The brothers joined the retinue of Takemikazuchi-no-kami and along with him the gods Futsunushi, Iwai no nushi and Takehazuchi and in their fight the against the invading star god. The battle lasted for nearly ten years and many of the mortals that fought beside the four gods fell, but the brothers survived. Before Mikaboshi was slain he cursed the two brothers, stating that they would be each other's foe for a thousand years before they would return him to his living form and bring him back to Earth."
Tadashi looked up at his parents, confused. "Why would he do that? The brothers won fair and square."
"Well honey, sometimes people just can't accept that that they have lost. For example, if someone was trying to hurt Hiro and you got in the way, would you accept being beaten no matter how bad you were hurt?" Maemi asked with a small smile.
After thinking about what his mother said, Tadashi shook his head. "No, I would fight for Hiro. But how is that the same thing? I thought he was out to destroy our world?" Tadashi asks a little confused.
"He was, but you have to remember that his original intention was to avoid the fate that he feared." Tomeo informed Tadashi.
Tadashi was bewildered by this idea, and furrowed his eyebrows. "Fear? It took four gods and hundreds of warriors to fight him, so what did he have to fear?"
Tomeo sighed and leaned back in his chair. "He existed before what we know today existed, our sun, our moon, our universe if you will, and was afraid of being destroyed by time, by the new... for lack of a better term, existence that he found himself in. The irony is that often the path one elects to avoid one's fate leads straight to it. And as is often the case, tyrants beget their own downfalls," he said.
Tadashi delves on what his father just said for a minute. Tadashi concludes that Mikaboshi's actions make sense, but the star god's fear doesn't justify them in the slightest. He trained his gaze on the book and found the place where he had left off.
"As Iwai no nushi and Takehazuchi finish off Mikaboshi, the star god chuckles before he dissolves into nothing. After returning to Earth, the curse on the brothers takes hold and due to an argument over a sibling's marriage a few months later, Kenuichio stabs Kioshi, almost killing him, but since he was cursed to live a thousand years more, he survived. And since then the two have continued to fight. Takemikazuchi-no-kami, knowing that he was responsible because he sought their aid, asked what could be done. He found out that one god can't remove the curse of another but can utilize the language of the curse to offset it. Takemikazuchi-no-kami saw that the fight was over the marriage of a younger brother and blessed that brother's line so that in a thousand years, the heir of that line would bring peace to the warring brothers." Tadashi pauses, having heard Hiro yawn.
"Well looks like Hiro won't hear the end of it," Tomeo jests.
"I am still awake," Hiro said, unconvincing due to his exhaustion.
"To this day the brothers fight among the stars, waiting for their chance for peace, the words of Mikaboshi haunting them. But peace shall be theirs once the thousand year curse is over," Tadashi finished the story and hands the book back to his father.
"Is any of that story real, Dad? I mean traveling across the stars like that. It can't be possible," Tadashi asked his father.
"I don't know, son. When The Tale of The Bamboo Cutter was first told, everyone knew you cannot actually travel to and from the moon, but in 1969 mankind proved that one can. Who knows, try to get some sleep, busy day tomorrow," Tomeo says as he and his wife tuck their sons in.
Tadashi turns to his brother as his mother pulls the door shut behind her, the light disappearing along with her smiling face. "Don't worry, Hiro, I will never try to kill you over a marriage. Sweet dreams, my magnificent little brother," Tadashi jokes as he sees Hiro drooling in his sleep.
Chapter 1 Hiro 17
It has been three years since Dr. Robert Callaghan was convicted of his crimes as 'Yokai'. That being said he still teaches at San Fransokyo Institute of Technology (SFIT) via teleprompter, he's not paid anything but to deny the students his knowledge is not fair to them. To his credit he pleaded no-contest to the charges.
Other than that the big thing on campus was the graduation of the prodigy Hiro Hamada, as it took him a little more than two years to complete his Bachelor's, he will be graduating with his three college friends, GoGo, Wasabi and Honey Lemon. Fred, however, was… well... Fred. He sat in the audience with Cass watching the ceremony along side the parents of GoGo, Wasabi and Honey Lemon.
Hiro looked over the rest of the graduating class and took a deep breath before smiling at the crowd. "Good afternoon everyone, I am Hiro Takachiho, although you may know me better as Hiro Hamada. I have spent days trying to think up something to say up here, but honestly I had to conclude that I had nothing, no ideas. Useless, empty brain." Hiro chuckles to himself nervously before continuing. "But there is someone else who has something to say. My brother, Tadashi. Ow," Hiccup says.
At the base of the stairs, Baymax was activated by the code word. He came up the steps to stand beside Hiro. "Hello. I am Baymax, your personal healthcare companion. I was alerted of your need for medical attention when you said 'ow'. On a scale of one to ten, how would you rate your pain?" Baymax asks in a monotone voice.
"A one, buddy. Could you play Tadashi's recording?" Hiro asks the tall inflated nurse robot.
Baymax plays Tadashi's recorded attempts in testing the first Baymax. After the video was over, Hiro turned to Baymax.
"Thank you Baymax. I am satisfied with my care," he says and Baymax goes back to his case and deactivates. "It's been a rough road up to this point, and we each may still have a long way to go. But we can do anything, we just need to every once in a while look at things from a different angle," Hiro finishes and returns to his seat back among the graduates.
As the ceremony continued, although the things that were most noticeable to Hiro were the real names of his friends. Wasabi went up when 'Ginger Chief' was called, Honey Lemon went up when 'Aiko Miyazaki' and GoGo was not far behind Hiro when 'Leiko Tanaka' was called. Hiro knew Wasabi, Honey Lemon and GoGo were nicknames, but still. After the final remarks, the caps were thrown into the air. It was a bit of an issue trying to get Baymax's case, but he was able to rejoin his friends, Fred included.
With them was Cass and several people Hiro at first didn't know but after a few seconds recognized. One was a woman that looked exactly like GoGo, but minus the purple streak in her hair, a man that was dressed much like how GoGo usually dresses and popping gum just like her, clearly her father, a man that was pretty much like Honey Lemon in appearance with a woman that matched Honey in personality; Hiro concludes that they are Honey's parents. There was also a woman that looked very much like Wasabi with a man that seemed to be an even worse neat-freak than Wasabi, they are definitely Wasabi's parents. Honey and her mother were adamant about taking pictures of the graduates and their families. The trickiest ones to take were the ones that both Honey and her mother were in. After the last photo they all got into Wasabi's father's van for the real celebration.
They arrive at the Luck Cat Cafe in reasonable time, and Wasabi's parents go into the kitchen and begin making the dinner. The other parents helped with the set up, surprisingly even Fred was very helpful as the four graduates put on something more festive.
The party is nice but for Hiro something, no someone, is missing, Tadashi.
Normally Cass didn't serve alcohol, but this was one of the few times she broke out the sake, the Tanakas brought soju, the Miyazaki brought Ginjinha, Fred had Heathcliff bring over some beer and Mrs. Chief brought Moonshine, much to Wasabi and Mr. Chief's dismay. As the meal, feast rather, is being laid out, Hiro goes up to his room, leaving Baymax's case at the foot of the steps.
Hiro walked over to Tadashi's side of their room, or at least it use to be their room. Nothing had changed. Every so often he would look through his brother's old things and remember all of the memories they had created together, all the fun they had had and he would also recall all their fights and arguments, but Hiro could still feel Tadashi's love, because Tadashi cared enough about Hiro to be angry with him.
There was one box Hiro never looked at though. Written on the top of the box in black sharpie were the words Okasa to Otosan. Hiro took a shaky breath before lifting the lid off the box. Inside there were old family pictures, his mother's small, painted wooden jewelry box and his father's cufflinks. He pulled out a dusty book and set it on Tadashi's bed with a small smile. "The Silver and Ebon Brothers," he whispered. His eyes followed the neatly written Kanji across the worn pages, and the story slowly came back to him. He remembered the first time Tadashi had read it; the warm smile on his mother's face; the sparkle in his father's brown eyes.
A knock broke Hiro's focus. He closed the book and put it back in the box before putting the lid back on the box and turning to Cass.
"Hey, my college grad, you're missing the party," Cass said as she comes into his room, noticing the sad look in his eyes and frowned. "What's eating at ya?"
"I was just thinking about them not being here, so I came here to..." Hiro trailed off, unable to continue.
"Oh honey…" Cass sat next to him on the bed and rubbed his shoulder. "I miss them too, we all do," she said.
"I know, Aunt Cass. I just wish I had more to remember them by then some stupid book," he says.
"Isn't that the book he used to read to you?" she asks.
"Yeah, every night until he started high school. I had to read it by myself after that." Hiro remembers how his brother read it and did everything he could to keep Hiro's focus on the story, acting out some scenes and trying to get Hiro to act along.
Seeing the look on Hiro's face, Cass continues, "You stopped when you entered high school too, dear. After that it was cramming high school classes and sneaking out to bot fights."
"Yeah," he sighs, smiling a little at the memory of his short bot-fight career. He had to admit, he is most likely still San Fransokyo's best bot-fighter. Granted he hasn't fought since the night Tadashi took him to the 'Nerd Lab'. After the funeral to when Big Hero 6 formed, Hiro was too depressed to do anything really. After the battle with Callaghan, it was always school, homework, working on improving Baymax's abilities and Big Hero 6 duties. Since then San Fransokyo had lifted the bot-fighting betting ban and now there were tournaments for bot-fighting and of course bets on fights, but he never had time to compete.
Cass nods slowly and patted his shoulder. "You know, your father used to read it to you and Tadashi. The last time he read it was the night before..." Cass stops, her words suddenly caught in her throat. Her sister's death still hurt, although the wound was not as fresh as Tadashi's death, but some things never fully heal.
Not wanting to make this a moment to mourn the deaths of their family, Hiro gives his aunt a weak smile. "It's okay, I don't remember them anyway. We should probably get back down there," Hiro says.
"You're right. I can't wait to see how everyone's face melt when they eat my wings," Cass chuckles as she stood and left the room.
"Well... nii-san [4], I really miss you. I hope I've made you all proud today." Hiro says before following his aunt.
He chuckles as he hears Baymax activate downstairs, following ten distinct voices saying 'OW! OW! OW!'. Only one thing could cause that much pain, Aunt Cass' wings.
Elsewhere in the greater cosmos, among the stars of Genbu [5], two lights flash menacingly.
On a desalinate planet, two men dressed in armor from the Henian Period fight each other. One's armor is a reflective silver in color the other is pure ebony. Again and again their katanas meet, resulting in a flurry of glowing sparks that seem to dance in the air for a moment. They are silent except for their breathing, which becomes heavier and heavier by the second.
They collapse on to their backs in unison, their warm breaths puffing out white clouds in the cold. The one in ebon armor speaks first, his tone one of defeat and honest concern. "Why are we doing this, Kenuichio?" he asks the other man.
"I do not know anymore. It has been so long that I know not anything but the need for victory, Kioshi," Kenuichio answers.
The two just stare into the starlit galaxy around them, at loss for words. After a few long minutes, Kenuichio turned his head to look at his brother. "It was because of our brother's marriage to that… that Chon [6] serving girl," he spat in disgust.
"Yes, I remember now," Kioshi agrees. "But, if you don't mind me asking, what did you have against her anyway? So what if she was a serving girl? It wasn't like Hiro was going to be more than a peddler, so they were of equal status, and he still ranked above father. As for us, we became warriors by dumb happenstance. So what if she was from Korea? What if she was from China? What if she was Ainu? Would it had made a difference to him? I doubt it, so why should you or I have cared?" he asks his argent [7] brother.
"What about our family's honour?" Kenuichio calls out in fury only to start a bout of coughing.
"And trying to kill him over the matter was worthy of honour?" Kioshi asks rhetorically. "Kenuichio, this has been a war of a thousand years over stupidity. Let us agree that we disagreed on our brother's marriage and that right now the whole argument is mute."
Mulling it over, Kenuichio had to concede with his ebon twin. "Alright. So what happens now?" he asks.
"You two take me back to Earth," says an ancient voice, deeper than the void between worlds and older than the universe.
The brothers struggle to get back to their feet and take on defensive poses. "Mikaboshi!" the brothers growl.
They took a step back back as they saw the dark body of the rogue star god manifest in front of them. It is obvious that he was nowhere near as strong as he once was. If it had been 800 years prior, the brothers would have faced Mikaboshi right then without a second thought or doubt about their victory. But they knew that they could not face him here and now, they are to weary from their thousand year clash, they need help, and there was only one place could they get that help. Back on Earth. The two turn to Earth and using the chi begin to run across the stars. At the end of their path, unbeknownst to them, is the city of San Fransokyo.
Mikaboshi chuckles as he watches the two brothers flee, knowing that it has enabled him to start his return to Earth. "Run. Run as fast as you can, fools. You only make it easier for me to follow," Mikaboshi says to himself and starts his own track to Earth.
Back on Earth, in the Lucky Cat Cafe, the party had mostly wrapped up. The graduates, Fred and Baymax were cleaning up as Mr. Chief offers everyone a ride, Fred said he has it covered for him, Wasabi, GoGo and Honey, this was the first time Hiro learned that the three live in the same apartment complex, one the same floor, Wasabi across the hall from the Honey and GoGo. Hiro feels a little shame, he actually knows so little about the four people closest to him. Not only does not know their real names, he doesn't even know where they live. After everything was cleaned, and the other parents have left.
"Alright kids, you all can do what you want until midnight. Here are the ground rules, 1) you break it you buy it, 2) More than 75% of the alcohol has to be untouched, 3) Hiro, you are allowed only one girl in your room for the entire night 4) If Baymax is activated, you four are banned from the Lucky Cat for the next year and Hiro, you'll be cleaning everything, from the roof, to kitchen sink, to the tub, and everything inbetween for the entire year, and no you will not be a payed employee, and 5) Wasabi, you are in charge, you can make all other calls as long as they don't conflict with the previous 4," Cass says to the five human members of Big Hero 6.
Stocked at the third of Cass' ground rules, "Wait, hold on, what do you mean by me having a girl in my room?" Hiro asks in bewilderment.
Seeing the confusion on her nephew's face, Cass rolled her eyes. "You're 17, there are two attractive young women here and you are going to be drinking alcohol." She answers.
"But..." Hiro starts.
"You get a pass on drinking tonight and I am not pressing charges of statutory rape for the next," she squinted at a clock, "16 hours. Good night." She starts towards her room, but stopped and opened a drawer before tossing something to Hiro. "Don't use them all if you can help it. Last hug." Cass then hugs a confused Hiro as he looks at what he caught, a box of Trojan 'Her Pleasure' condoms.
"Um... Aunt Cass..." Hiro wonders why his aunt has these.
"I am seeing someone, you haven't met him. Good night." Cass says quickly before turning away.
"Wow... and you guys act like my collection of Kaiju and comics is weird." Fred says stoically.
"Okay now that Cass put me in charge, show of hands who will actually obey that rule?" Wasabi asks.
Fred throws his hand into the air and looks around at the other four Big Hero 6 members staring at him. "What? Is there something on my face?" he asks. He puts his hand down to scrub at his face.
"You're okay with taking orders from me?" Wasabi asks slowly.
"Well duh, you are the oldest of us, you are most responsible of us, and if anyone is going look over the rest of us and make sure we don't get into trouble, it's you. Besides if I get banned from here, I am going to get banned from your parents' restaurant, GoGo's dad's shop and Honey's mom's lab. Also I think my dad will give Heathcliff a month off and I'll have to take care of everything." Everyone just blinked at Fred, surprised that he even knew what responsibility was.
"Looks like I'm in," Honey Lemon says raising her hand sheepishly.
Hiro also raises his free hand while trying to hide the box behind his back, it's not hard to understand why, he doesn't want to clean everything for a year.
"GoGo?" Wasabi asks. She reluctantly raises her hand and pops her gum.
"Alright. So how about a drinking game?" Wasabi asks, clapping his hands together.
"Never Have I Ever is not fair, we know too much about each other," Honey points out, while the statement is true it is not entirely accurate.
"I ain't doing Truth or Dare," GoGo says bluntly and pops her pink gum again.
"We could spin the bottle," Hiro suggests sheepishly as he holds an empty sake bottle up. No one has a better alternative.
"Alright here are the rules, you spin the bottle, whoever it lands on you have to kiss on the lips, the person can 'dodge' a kiss by taking a shot. You can dodge up to five kisses, but you have to take additional shot per kissed dodged. The spinner can re-spin five times a turn but has to take an additional shot per re-spin. Now if you land on the same person two rounds in a row you have to kiss on the neck, three rounds in a row, the clavichord. I am going to referee, so I am out of the game," Wasabi tells the group.
"Why... oh yeah it's your night to be DD," Fred says.
Not familiar with what Fred means, Hiro asks, "DD?"
"Designated Driver, you see when a group goes drinking, it's customary to have someone who doesn't drink anything alcoholic to drive. Also I don't trust GoGo behind the wheel of my car since she totaled my last one," Wasabi informs Hiro.
"It's been three years, woman up and get over it." GoGo states a little irritated. "I'm spinning first."
GoGo takes the bottle and spins it. It lands on Honey Lemon.
"Hit me," GoGo says and takes the shot Wasabi hands to her.
She spins it again and it lands on Fred. "Hit me," she groans before throwing back both shots and shaking her head at the burn in her throat.
She spins again and it lands on Hiro. She rolls her eyes before grabbing Hiro by his shirt and after giving him a quick peck on his lips, she he effectively throwing him back.
"Spin the bottle, dofus," She orders Hiro.
Hiro has a small smile on his flushed face as he spins the bottle. It is going to be a long night…
Hours later: "But Gingie-kun, I don't want to go," Honey Lemon whines as Wasabi carries her to his car. "Just one more round. Please? I'll be good."
"Not on my watch. Fred stay right there I will get you next." Wasabi calls over his shoulder as he places Honey in the front passenger's seat and buckles her in. She drunkenly tugs at the seat belt but was unable to get it off.
"I kissed a girl and I liked it-"
Wasabi shut the door on Honey, pinching the bridge of his nose. "It's a good thing I confiscated anything she can take a picture with. Alright Freddie, you're next," Wasabi says as he heads back in. He opens his arms when he sees Fred stumbling towards him.
"Ha! You are no match for Fredzilla's Super Jump!" Fred jumps but Wasabi steps to the side. "Fredzilla fell hard." Fred mutters into the ground "Can Fredzilla get a hand up?" he asks the still sober plasma expert.
"Here we go, big guy." Wasabi picks Fred up almost without effort and throws him over his shoulder.
"My hero," Fred whispers in awe, stroking Wasabi's back.
"I've bench pressed dumbbells heavier than you." He puts Fred into the back set behind Honey and buckles him in as he joins Honey in the same song. Wasabi shuts the door with a groan. "I am going to be stuck with that all the way home." He says looking at the sky.
He goes back in to get GoGo but instead finds a note on the kitchen table. "Well that's just great."
He leaves with the two drunk singing Big Hero 6 members in his car. "Alright, that's it! GoGo is the next DD," he says to himself as the two start singing 'Fred's Angels'.
Back in the Lucky Cat Cafe, as Wasabi is carrying Honey Lemon to his van, GoGo helps a clearly drunk Hiro to his room, she too is drunk, but she seems to have a little more control.
"Alright, nerd, let's get you to bed," GoGo says and then laughs, "Get you to bed. Never thought I say that. But you drank a lot."
"No more than you," Hiro pointed out as he somehow manages to open the door to his room.
"Exactly my point..." GoGo says and starts laughing. "How much did I drink?"
"No idea, but I know how we might find out. I am Healthcare, your personal Baymax companion."
The two can't stop laughing as a drunken Hiro impersonates a low battery Baymax. "I scan you now... complete scan… Baymax..."
GoGo lets Hiro fall onto his bed as he continues the impersonation. He gets back to his feet. "Shhshs... we jumped out a window." Hiro whispers.
GoGo too falls on to the bed and goes into a ball as people do when they laugh too much.
After a short laughing bout, the two are on the bed looking straight into each other's eyes. Slowly both take their free hands and place them on the other's check. "You are the most beautiful person in the world," Hiro says tenderly. "Wow, I never thought I could ever say that."
GoGo can tell that Hiro meant what said, "You know, where my mom is from, Korea, there is a belief that when you are drunk you show your true self," GoGo says as she brings her hand into Hiro's hair.
"Well if that is true, I must really love you, not as if your my nee-san [8],but like I want you in my life forever and not like a friend, like that I need you with me," Hiro says.
Why is my heart racing, why do feel this… thing, I've never cared about what other's thought about me before. GoGo's thoughts flood her mind, this is a new sensation, a new frontier for her, part of her wants to back away but another part wants to go forward.
"Hiro..." GoGo whispers and the two pull each other closer and closer and closer and…

Author's Notes:
First and foremost, I admire that in Big Hero 6 there is no romance drama and that everyone of the main cast are true friends or have a sibling-like relationship. That being said, I am shameless HirGo shipper, another couple I do ship would have to be Wasabi and Honey Lemon (not sure what that ship is called) Not saying anything against Fred or Tadashi and those who ship them with anyone (with the exception of Hiro x Tadashi... sorry but incest is a no-go), it's simply not my cup of tea. You have your ship, I have my ship, let's agree to let Disney decide which gets the cannon (pun intended)
[1] I am using the Marvel Comic names as the real names of the characters, 'Hamada' is Cass' name and Hiro and Tadashi take it on for most purposes, but Hiro's legal surname is Takachiho.
[2] Okasa is one of the Japanese words for 'Mother'
[3] Otosan is one of the Japanese words for 'Father'
[4] Nii-san (pronounced with only one long 'I') means older brother
[5] Genbu is the Japanese term of Xuan Wu, or Black Tortoise (the more accurate translation is 'Dark or Mysterious Warrior') and is a major constellation of the Northern sky as constellations are understood in that area of the world
[6] 'Chon' is a derogatory term for Korean in Japanese, it's most likely a short form of 'Chosenjin'. 'Chosenjin' literary means 'Person/People of Korea' and was originally a matter-of-factual neutral statement. Today both terms are often used to insult the people of Korea, especially in Japan. I have no love of insulting people and the use of 'Chon' here does not reflect in away way my feelings for the Korean people. This is solely meant to establish the falling out between Kenuichio and Kioshi. Now Kioshi may use 'Chosenjin', but will have no idea that it too is an insult and will mean it in it's original way. As to why Kenuichio uses 'Chon' it is meant to show him as the 'bad' brother, as to why he is the 'bad' one of the two, well in the original comics the Silver Samurai was for a time a villain and he did kill Kioshi, who was a police man at the time, who comes back for justice for his murder as the Ebon Samurai
[7] argent is a fancy way to say 'silver' and is based on the Latin word for 'silver' which gives silver it's symbol of 'Ag' on the periodic table
[8] Nee-san (pronounced with only one long 'e') means older sister, this refers to the fact that GoGo takes on a big sister type role for Hiro in the movie. Since GoGo is of Korean descent, Hiro probably should have said Noona (it means the same thing, but let's give Hiro a little slack, he's drunk after all)
