The Banzai Brothers.

Located near the dark, filthy botfighting alleys of San Fransokyo, a little restaurant named Tako Taco—known for serving both Japanese and Mexican cuisine—has just closed down for the day. Dominguez and Komeiji, known as the "Banzai Brothers", lived in an apartment behind the restaurant where they can see the dark, narrow alley outside their window.

Despite their nickname, neither of these two hotblooded men is actually blood-related. They first met when they're both members of an embarrassing and temporary mariachi band, and the two considered each other close as partners. Especially they both share common interests: botfighting and blowing things up.

Their salary as chefs couldn't help pay their rent but they discovered other ways to earn good cash. They have taken up botfighting and they're unbeatable in pair battles. However, they often get caught by the police or ended up brawling with the sore losers so much they decide to take an alternate and "safer" job when they're not so busy building battlebots or whipping up tostadas.

The Banzai Brothers set up a private website where the police couldn't trace it and they offer their services as secret hitmen who are skilled with explosives. They usually demand to see their client in person before they take a job and it so happens one night they received a visit from a mysterious man.

"Robert Callaghan," Dominguez, the older Banzai Brother, said as he watched him sat down the tattered couch across him. He puffed a cigarette. "It's unusual we have client at 2 in the morning, but now I can see why you wanted to see us at this late hour. Can't have a well-known college professor be seen going to a shady neighborhood while there's people still awake, huh?"

The grey-haired robotics professor narrowed his eyes around the living room of the apartment; it reeked of beer and cigarettes, and not to mention sweltering since the air conditioner is broken. The floor is filled with metallic objects and stacks of papers and magazines in sloppy piles, making it harder for anyone to navigate.

Callaghan hoped these men are more competent than they looked. He wanted to remove his black trench coat to cool off this suffocating heat but he chose not.

"I have only one request and I'm willing to pay you half the money right now, and the other half after you completed the job," he told them.

Komeiji belched rudely. He was leaning against a bookshelf with a beer bottle in hand. Dominguez gave his partner a look for being nasty before turning to Callaghan.

"So, what's the job?" he asked. He then stuffed his cigarette into an ashtray.

"In two weeks from now there'll be a science showcase held at SFIT's exhibition hall," Callaghan said. "One of the guests is Alistair Krei."

Komeiji spat out his beer in shock and started coughing.

"This is rather interesting," Dominguez smirked, leaning forward. "What did he do to deserve to blown up?"

"Let's say he ruined my daughter so much she might as well be dead because of him," Callaghan answered coldly. His eyes flashed with tranquil rage that it brought shivers down Dominguez's spine.

"You hate him that much, huh?" Dominguez muttered, rubbing his chin. "And you want us to help you destroy him. Well, I can recommend a Banzai Brother specialty: blow up an entire building until it's all in flames. By the time his body can be found, there won't be much of him left."

Callaghan thought about it and a cruel smirk formed in his lips. "Sounds perfect."

Komeiji laughed as he sat down next to his partner. "Name your price and we'll do it, old man."

Callaghan took out a checkbook and began to write something in it. After he's done, he gave a check to the Banzai Brothers, who looked at it and they both whistle in unison.

"This is only half the payment?" Komeiji cried, highly impressed. "Why don't you give us the other half now and we'll just bomb him at his home tomorrow instead?"

"No! It has to be at the showcase!" Callaghan growled. "I wanted to be there to see his face full of fear and helpless while he's waiting to die."

"Whoa, man, I was just kidding," Komeiji said, wide-eyed with fear.

"Besides, we're running low on supplies, especially our nitroglycerin," said Dominguez. "We need some time to prepare the stuff."

Callaghan wrote down the date of the showcase and gave them to the two men. Then he stood up, ready to leave. "Don't mess this up."

Dominguez chuckled darkly. "Trust us, Mister Callaghan. We're very good at our job."

Two weeks came and the two Banzai Brothers, disguised as janitors, arrived at the showcase earlier before anyone else that day to help Callaghan secretly set up the machines containing explosive chemicals around the building.

"These babies are triggered by heat," Komeiji said as he placed a hidden bomb near the entrance of the main lobby. "If you don't have anything to protect you from the blast, you'll be all over the place."

Dominguez looked around to make sure they're not being overhead.

"When you're ready," he said in a low voice, "you better figure out to start a fire or your plan will be wasted."

Callaghan checked his watch. He looked distant for some reason. "I'll see you two later tonight after the showcase." He then gave them the check of the other half their payment. The Banzai Brothers watch him walk away before the look at each other. They're wearing similar evil, shadowy expressions.

"You know, bro," Dominguez spoke in a low voice, laced with cruelty. "This building will still be full of people tomorrow night after the showcase ended."

"That's right, bro," Komeiji smirked. "And there'll still be people around when the fire breaks out."

"But imagine how much more fun…"

"The hot surprise it'll be for them…"

"… If we dismantle the fire alarm system," the two men finished in an ominous note.

Yuan and Yasuo.

Yuan, an SFIT student majoring in microbiology, was one of the last people to get out from the exhibit hall. He was in the second-floor bathroom when he heard the screaming and saw the flames. He didn't know why the fire alarms didn't set off earlier but he cursed his bad luck for attending a stupid showcase in the first place.

He looked back, staring in morbid awe as the smoke rise menacingly. He noticed Tadashi Hamada, a fellow student, running inside the building leaving behind a small boy—probably his brother-in front of the steps.

Is he crazy?! Yuan thought wildly. Why would he risk his life to run back inside? Was he trying to save someone?

Then the small boy moving forward up the stairs. Dashing over quickly, he managed to grab him by the back of his hoodie.

"What are you doing?!" he yelled as he struggled to pull Hiro back. "You're going to get yourself killed!"

"My brother is inside!" Hiro screamed, his voice filled with fear. He's clutching Tadashi's baseball cap. "Someone has to help him!"

"Just forget about him!" Yuan snapped. "Don't be an idiot!"

Hiro ignored him and pulled himself free, leaving behind his blue jacket hoodie in Yuan's hands as he disappeared inside the burning building. Yuan could feel the heat from the flames getting stronger and he cursed at both Hamada brothers' idiotic bravery.

A minute later, Tadashi came out. He was coughing and some parts of his clothes are a little signed but he was unharmed. Yuan, now frightened for the other boy, told Tadashi that he tried to stop Hiro from entering the building. He saw the look of horror on Tadashi's face. Before Tadashi could even turn back to retrieve Hiro, the explosion happened.

Yuan fell backwards from the shockwave. The jacket hoodie fell from his hands.

When he regained his senses, he saw Tadashi Hamada screaming and crying his little brother's name. The police and firemen were trying to hold him back, preventing him running inside. He saw Tadashi's aunt and his friends standing on the side, horrified and in disbelief of the situation.

"LET ME GO!" Tadashi roared. "MY BROTHER NEEDS ME! HIRO!"

Yuan could only silently return the jacket hoodie to Tadashi's aunt, who is now trying so hard not to crumple and cry like her broken nephew. And then he left the site without looking back.

Days afterwards, the fire accident and the deaths of Professor Callaghan was all over the news. Yuan found it strange that they didn't cover so much on Hiro Hamada's death but he believes it's because Callaghan is a famous scientist. He couldn't decide whether to be disgusted or not, but he did told the kid not to run inside the building.

"Serves him right," Yuan muttered as he finished his breakfast at his home.

He sensed his younger cousin Yasuo entering the room. He's holding a small bouquet of white chrysanthemums. He appeared to be distraught.

"Y-Yuan, since you're going to school, can you take these with you?" he asked in a small voice. He sniffled. "Th-they're for H-Hiro… Hiro Hamada's memorial."

Yuan looked at the flowers disapprovingly.

"What am I, a delivery boy?" he asked rudely. "The dead have no use for flowers."

"B-but I knew Hiro," Yasuo protested. He was on the verge of tears. "W-we're not even classmates in high school, but we've talked before and I liked him. W-when I heard he d-died, I…"

"Oh, shut your mewling. Why do you care so much for a nobody?" Yuan snapped loudly. He stood up and dumped his cereal bowl in the kitchen sink. He then snatched the chrysanthemum bouquet from Yasuo's arms.

"You should be focusing on fixing your robot for our next botfighting pair battle," he told Yasuo coldly as he threw the bouquet into the trash bin. "If you want to attend that botfighting tournament in Japan, you have to raise up enough cash to travel there." He walked off, muttering under his breath. "It's a shame your old man won't lend us the money..."

Yasuo stared at his feet sadly before he left home for school. He let the tears roll down his face as he continued to miss an old friend he barely knew but wished he could have gotten to know better.

Weeks later, both Yuan and the Banzai Brothers would later meet their karmic deaths at the hands of a grieving young man who never knew they're indirectly responsible for his little brother's presumed death.

Detective June Park.

Detective June Park stared directly at Hiro Hamada as he sat on a chair. Standing nearby are his friends and Aunt Cass. After Abigail was apprehended and taken to the hospital to be treated for her wounds, Park interrogated Hiro and his involvement with the criminal, and Hiro answered every question as honestly as he can.

"So, let me get this straight," Park slowly said as she rubbed her forehead. "Miss Callaghan kidnapped you and forced you to make miniature robots for her criminal purposes?"

"Microbots," Hiro corrected her. He looked so pale as though he had not been sleeping well and his eyes were heavy from constant crying.

"And would you care to explain why these microbots were found in the garage and being used by your missing brother?" Park asked, eyeing from Hiro to the others.

"Those were just extra microbots that I didn't bring to the showcase, not the same ones that were stolen by Abigail and the ones I made for her," Hiro explained. He and the others decided to change their stories a little under Gogo's suggestion to keep the Hamada family's record a little clean as possible.

"Are you aware that your brother Tadashi tried to attack me with them?" Park demanded. "He accused me for implying that he's a criminal."

"Tadashi… wasn't in a good place that time," Hiro said quietly. He thought of his brother and the image of him falling into the portal before it exploded flashed before his eyes. He fought back his tears. "I don't know what he was thinking, none of us knew what was going on with him. But I can assure you that he's not responsible for kidnapping the engineers or in cahoots with Abigail."

"He still fled and even attacked several officers," Park reminded him. "He still needs to pay for his reckless actions. I understand you're his brother and want to protect him…"

"Detective Park," Hiro choked out. Tears roll down his face. Aunt Cass walked over and placed a comforting hand on her nephew shoulders. "I missed my brother so much. When I heard what he did a few days ago, I was shocked. I didn't want to believe it. But I know he's still a good guy no matter how much he changed. I just… wished I could have been there to stop him."

Park felt pity for the young teenager. Maybe she was wrong that Tadashi isn't a criminal secretly working for Abigail and neither Hiro nor his friends knew where he had gone. Perhaps she can stop trying to hunt him down for a while... Her superiors didn't even believe her reports of a college student using nanobots to escape the city. And since he was wearing a dark visor helmet last time she saw him, she could protect his identity out of sympathy for the Hamada family. They've already suffered enough.

"Thank you for your time, Mr. Hamada," Park said gently. "This is the last time you'll hear from me. If your brother ever decides to show up, I still have to arrest him. It's my duty." She paused and gave him a small smile. "However, I will let you know so you can see him again."

Hiro smiled back even though he knew it was impossible for Tadashi to come back.

Park walked out from the Lucky Cat café and sat inside her car. Her minds is racing; Abigail already confessed her crimes and explained her father was responsible for the fire incident, so both cases were solved. She still needs to look into the mysterious murders of the Banzai Brothers and a young man named Yuan.

At first they don't seem to be related to the Callaghan case, though she remembered interviewing Yuan a week after the fire since he was one of the witnesses who saw Hiro running into the burning building before it exploded. She even found several explosive materials in both Abigail's and the Banzai Brothers' homes. According to the landlord owning the apartment where the Banzai Brothers lived, the man had seen Professor Callaghan and a woman (who fit Abigail's physical description) coming to visit the two men Brothers late at night.

Park assumed the two unrelated "brothers" and Yuan must be involved with the explosion and they were killed off by Abigail so they'll remain silent forever. However, Abigail told her that she never killed them, although she did say she went to see the Banzai Brothers after her father died because she wanted to learn how to build her own explosives. She even added that she has never seen or heard of Yuan. Park realized she reached a dead end with this case and she might as well give up much to her frustration.

"It looks like we'll never know who done in those three men," she said to herself as she drove away. Lying on the passenger's seat is a rolled up newspaper talking about the colorful superheroes named Big Hero 6's continued efforts stopping crime in the city. While she was grateful for their help, she couldn't help but feel jealous that they're doing a better job than her and the police force.

Project Silent Sparrow.

In a private room at San Fransokyo Hospital, Krei lightly knocked on the doorway to alert his presence.

"It's just me."

Abigail saw him and she sat upright in her bed. Her body and face are covered in bandages. There are some marks of faint bruises and burns left on her skin; she's slowly recovering each day.

"I thought you were the cops," she said. "I'm so tired of them hounding me with further questions which I've already answered."

Krei pulled up a chair and sat beside her.

"Candace decided not to come today," he told her. He's referring to his secretary.

"I don't blame her," Abigail sighed sadly. Despite wishing to see her friend again, she knew Krei's secretary has every right not to contact her. "I did use her and tried to blow her up. As well as our colleagues..."

She remembered the police telling her the engineers she kidnapped are still recovering though she was informed a couple of them are in critical condition. If they didn't survive, that's another few years added to her sentence...

Abigail is not looking forward being transferred to prison by the end of this week yet she must pay for her crimes. She hasn't forgotten what she had done and she wished she could take back all those things. She sent letter to apologize to Hiro and his friends, but she hasn't heard a reply from him. She believed Hiro isn't ready to forgive her yet but that's fine with her.

"What happened to Hiro's brother?" she asked Krei. "I haven't heard anything about what happened in Akuma Island since I got here."

Krei looked away from her, his expression turned somber.

"According to Hiro, his brother was pulled into the portal before it was destroyed along with the lab," he answered. "I was also informed the portal was unnatural since it just obliterated anything that was sucked into it. I don't think he survived. And if he did, by some miracle, he has disappeared without a trace. He could possibly never return home again..."

Abigail's face paled. However, she is secretly grateful that she didn't try to enter the portal herself.

"It's my fault," she said, staring down at her bed sheets. "The notes on my father's laptop said the dimensional-transportation portal would work..."

Her words got Krei interested. "Notes? Who wrote it?" he inquired.

"Someone named Dr. Ishioka," Abigail answered, shrugging lightly.

Krei became surprised and unnerved at the name. "I knew him," he said. "He's the grandson of the scientist who helped started the Akuma Island testing facilities. He, your father, and I go way back... In fact, Ishioka was the one who suggested the portal idea."

Abigail stared at him. "You said Project Silent Sparrow was your idea."

"I didn't know what came over me!" Krei suddenly protested. Guilt came crashing down on him. "It was an extraordinary idea but Ishioka wasn't going anywhere with it. So I decided to take the project as my own, without giving him credit."

Silence fell into the room.

"I tried to make it work before when Project Silent Sparrow was its early beginnings," Krei continued grimly and he avoided looking at Abigail. "It was difficult so I decided it's best to use it for convenience travel. But I guess since it wasn't my own research, I overlooked some possible bugs and other irregularities that could cause problems to the portals." He began to sweat. "I didn't know your father still had the old notes but I guess he kept them for some purpose he might use against me."

He rubbed his temples.

"I'm sorry for hiding this from you, Abigail," he apologized. "But I didn't want to satisfy your father's suspicions that I cut corners to get where I was today. I even tried to steal Hiro's microbot tech."

"But you didn't," Abigail stated. "You could have built copies of them and sell them on the market. You've stole someone's invention before, why is that one different?"

"Maybe because... Hiro's brother had stopped me," Krei replied after a pause. He remembered that day of the showcase. "I'm grateful he did because I don't know what new trouble I would have faced if I made my own microbots."

Abigail just looked at him. Her face is so difficult to read but Krei assumed she must be thinking of this revelation. He then saw her taking his hand into her own. Her lips formed into a small, regretful smile.

"I guess we're both thieves then," she said to him.
