'Tadashi is dead.

And it is the truth that will not change.'

Hiro thought that he had gotten over his brother's death. But somehow, nightmares would visit him. Hiro had dreamt a lot about his lost brother. Most of them was the last day Hiro saw him, the last moment of his life before the fire consumed everything and he woke up with shaking legs and teary eyes.

A year had passed since his brother died. Hiro told himself he had to get over it. He had to move on. Tadashi's lab was now his, and he would continue his brother's work. He's going to upgrade Baymax and made sure that not only he had Baymax, but also others.

Fred had joined his project after he's satisfied with his superhero's things. He wanted to help as well. And with Fred's supports, the contract had signed and Baymax had a chance to test his abilities with volunteers and some patients in the hospital that was owned by Fred's uncle.

"Tadashi would be proud."

Gogo said to him the day Hiro and Fred told the rest of the team Baymax was going to be tested in the real hospital. Everyone was excited and there was great celebration at Aunt Cass's café. [Aunt Cass was not going to let this success passed without a great celebration.]

"Go rest bud, tomorrow is your big day." Hiro said to Baymax who followed him into his room after the party. "I'm satisfied with my care."

When the robot had shut down, Hiro sat down on his bed. He sighed and smiled, taking Tadashi's photo in his hand.

"He is going to help a lot of people." Hiro smiled to the photo in his hand. "He will make you proud. I promise."

The boy who just had turned fifteen sighed and put his brother's picture to his chest. He laid down, staring at the wall.

"I wish I knew what you would say." Hiro said. "Oh, please don't be just," He said in Tadashi's accent and voice. ", 'I'm proud of you'. I know you have things to say more than that."

Hiro tried some different words and ended up laughing at his silly act. He put the photo back to his nightstand and gave a long sigh.

"I really wish you're here."

Hiro said, this time without a smile. Heaviness in his heart could be forgotten when he's with friends, Aunt Cass and Baymax. But when he's alone, his brother's death and the fire were still there. He was just a good actor to be able to hide it from everyone for so long.

"He is amazing."

Fred's uncle, Mr. Forest, was very impressed with Baymax's abilities and capabilities. He was also impressed in Baymax's cute appearance. The children and their parents liked him a lot. Although all Baymax did was walking around, scanning people who came into the hospital and suggested where they should register or what might help improved their health. His present was still comforting and it helped distracting children from their fear of doctors.

"Likes what I have told you uncle." Fred said with a huge smiled on his face. "He is amazing, so, what do you say?"

"Oh, I would say." Fred's uncle gave both Hiro and Fred a big smile. "Your robot will have three months of testing here. And if his performance passed, I will sign the contract and have you develop him for permanent use in my hospital. And I'm sure that if he got a job here, other hospitals would want him as well."

"Thank you! Thank you so much!"

Both Fred and Hiro beamed.

He was still woken up by nightmares. It's not every night he had to wake up sweating and felt his heart constricted with pain and sorrow.

His room was simple and plain. It made him missed his past a bit, missed the room he once shared with his little brother. He missed the mess they sometimes made together.

The alarm clock rang and he touched it gently to shut off the alarm. He yawned and got up. His messy hair made itself known when he saw his reflection on the mirror in his small bathroom. He did what he always did every day for nearly two years. Brushed his teeth, cleaned his face along with sleepiness, changed into something warmer than his pyjamas when he went for his 'before morning' run.

He went down stairs. The guard dogs let him passed through the main hall to the back entrance of the house. Their watchful eyes followed him until he was on the other side of the fence. The dogs were more watchful when he first arrived. He guessed they accepted him to be less threat to their pack. He hoped some days they would accept him as one of their pack members. It's awkward to be the only one that didn't get any face-licked when coming home.

The air was cool as always. It's 4am and himself in the past would still be under the cover at this time. But many attacks usually took place when humans were at their sleepiest time, 4 am. It took ten times of being thrown out of the cover at 4 am that made himautomatically woke up before 4 am. But he still had his alarm set at 4 am in case he was too tired to wake up.

The before morning run helped his brain to fully wake up. He ran around the abandoned area he used to run, using the dimmed light from the sky. He wasn't allowed to carry any lights so he had to remember the paths he ran each day. His first week of before morning run gave him numerous wounds from falling since he couldn't remember all of the paths yet and ended up stumbled into bushes and rocks.

After making 8.6 mile in one hour, he was back. The kitchen's lights were on. Someone had already woken up.

He went through the back entrance as always. The dogs watched him made his way up stairs to his room. He threw his clothes into the basket and grabbed his towel. His room had warm shower but he preferred coldness since it could strip the heaviness on his eyelids away better than gallons of coffee.

After the cold shower, he carried himself to his wardrobe. The clothes he owned now were also plain. If it's not white, it's black, dark blue or grey. He missed his mint-colored sneakers. He sighed and put his clothes on. But before he put his shirt on, he put on his gears, his hidden blades, first. After that he finished with his long sleeves plain white V-neck T-shirt.

His dark blue sweater and black blazer were waiting on his chair and his dress. He grabbed them both in one swift move and realized how much he missed his green blazer.

The kitchen was already crowded when he was down stairs. He nodded to the cooker and grabbed his plate, made his way to the other room where they ate and chatted.

The tables were already packed with people. They're all chattering and enjoying their time. He mentally sighed, he missed a time liked this with his brother. Each day he had to drag himself from his sorrow to face people and yet he still could force his smile out.

"Hey!"

The tall man waved for him to join them at the table near a giant window which showed them the magnificent view of the garden. He smiled at them and walked to sit with him.

"Good morning" The girl with long blond hair said to him while sipping her coffee. "I've heard yesterday you took them out in 2 minutes. 8 people in 2 minutes!"

"That's fascinating man." The tall man said. His eyes shone with excitement. "You're still a novice but I would be lying if I said your performance is novice."

"Well, I'm still a novice." He shrugged. "And I still have much to learn."

"Oh, so humble and gentle." The girl smiled before got up. "See you around. I've got some meetings to attend."

"See you around Mara."

He and the tall man waved her goodbye. Before the tall man turned to him.

"How is the mission yesterday? Is it easy, hard?"

"Normal" He sighed, couldn't bring himself to care what he had done. "I got in and I got out with the information. That's all. How is yours?"

"Freakin' disaster." The tall man groaned. "Those fuckin' Templar guards were much more than what we had expected. Two novices I got with me barely made it out alive. The recovery will take weeks. Bob wasn't in any better shape. He was still in bed."

"I noticed his absence." He nodded, digging into his meal. "Is the mission accomplished?"

"Yes" The tall man smiled. "We had killed that bastards and destroyed his weapon factory. Will take years for them to rebuild it. But we still had what we could take out before we bombed it. Oh, I'm going to be late, see you around."

"See you around Dave"

He nodded and the tall man bid him goodbye. He ate in silence and return the plate when he finished. It's 6:15 AM and he had works to do.

He went to the library that was at the far ended of the house. He had been assigned to finish three books today. He had finished two, better finished the last chapter of the third book before 8:00 AM.

After he exited the library he made his way to the lab underground. He spent times there building things they would need or repair gears that were needed to be repaired. After his shift in the lab was over, he went to the training ground for novices. He trained until 1:00 PM that he was allowed to eat. Then it's his lab time and back to training. He didn't like to train in both his sweater and his blazer, but sometime he had to fight in these clothes and he better got used to it.

His mentor called him in after dinner. And he was there in time to see the old man cursing under his breath when his favorite reality show announced that next week guest would be a celebrity the old man didn't like at all.

"You called for me?"

He asked and the old man nodded.

"Have a seat, son" The old man said, pointing his staff to the chair in front of him. When the younger one sat down, he continued. "I have seen that you have learnt and progressed so much in this two years. And I'm proud of you."

"Thank you mentor."

"That's not all." The old man smiled. "Now you can call me Mr. Norman. You no longer need to call me mentor."

The news shocked him. He knew what this meant. He was now no longer a novice.

"You mean?"

"You're no longer a novice." The old man chuckled. "And I, head of this Assassin's bureau, would like to announce that you're now an assassin. I have the grand master's permission to grant you your new rank. Welcome to the club, boy."

He was stunned but he nodded and stood up before kneeling on his knee. Mr. Norman touched his shoulder firmly and said what he had said to others before him.

"We work in the dark, to serve the light. We are Assassins."

"Nothing is true, everything is permitted."

Tadashi Hamada stood up after he the hand on his shoulder was gone. He looked into his former mentor's eyes and smiled. Mr. Norman smiled back and grabbed the file on his table before handed it to Tadashi.

"Your job tomorrow." Mr. Norman said, still smiling. "Have fun hunting."

"Yes sir"

Tadashi nodded and left. His heart sank. He had never wanted to kill, but here, killing was to save everyone. And killing was his job now.

He's now an assassin.

"Congratulation! Baymax's performance is fascinating and I'm happy to announce that he can permanently works here if you wish him to."

"Yes!"

Hiro jumped up and down in excitement after 3 months of Baymax working in the hospital. Now Fred's uncle had granted the health care robot a permanent job at his hospital.

"Thank you so much!" Hiro smiled, his brightest smile he hadn't smiled in years. "I, I don't know what to say. He's going to be very happy, right Baymax?"

"I'm a robot. I don't have emotions." Baymax said and Hiro's face doomed down. The robot quickly added. "But if being 'happy' improves your moods, yes, I'm happy."

"No! You're not just happy. You're very happy!"

"Yes" Baymax nodded to Hiro and turned to Fred's uncle. "I'm very happy to work here."

"Excellent" Mr. Forest smiled to Baymax. "I will see you around soon, . Hiro! I'm very amazed by your work. He is likes no other! Your idea is amazing."

"Oh, well" Hiro tried to keep his smile but failed. "Actually, Baymax is the project my brother started, but he passed away, so…"

"I'm sorry." Mr. Forest said. He put his hand on Hiro's shoulder in an attempt to comfort him. "But I can guarantee that your brother's idea didn't die with him. Your robot is going to help a lot of people. And I'm looking for the upgrades your might add to him in the future. You're a talent kid. I'm sure after Baymax, you're going to create innovations that will help so many people."

"Thank you Mr. Forest" Hiro smiled. The bitter memories of his brother wasn't gone. He just pushed it aside. "I might add more knowledge about conversations into Baymax. I want him to be able to create more conversations with the little kids. Someone told me that talking helps reducing stress."

"I agree." Mr. Forest smiled. "But nonetheless! He's working here now. And that's what we should celebrate. I'll call Fred and let him knows he has to throw a party. Get ready for a party young man!"

"They're really relatives."

Hiro said to Baymax while watching Mr. Forest danced out of the room to grab his phone and call his nephew. Baymax turned to him.

"They're absolutely related. Their DNA and physical appearances are 90% matched, also their blood-group."

Baymax exclaimed and Hiro rolled his eyes, but he smiled nonetheless.

It's been months after he became an assassin. Tadashi didn't feel better much. When you're an assassin, you have to kill more than the novice had. He tried to subdue every guards he got passed than stabbed them in the chest. But he still had to eliminate his target, which meant he still had to kill.

He was sobering under the large tree in the garden after he had reported to Mr. Norman about his latest mission. He had killed one of the Templar's supporter, made it looked like a car accident. He was still sobering when Mara approached him.

"How is your day?"

"Normal"

Tadashi smiled at his friend. But the more time had passed, the more faked his smile was. He never appreciated killing to solve problems. But now killing was not solving the problems either, it's just what he had to do.

"You looked tired." Mara said, shifting her weight to another leg before continued. "You should have more rest. Dave told me you got up before 4am for a run every day. You don't have to push yourself that much."

"I'm used to it."

Tadashi said nonchalantly. He didn't want to imply what he's used to, his lack of sleep? His nightmares? Or his pain?

Mara seemed to be thinking for a while before she said.

"Hey, you're not staying here forever you know?"

"I know." Tadashi nodded. "And if they're going to send me somewhere, I hope it is Berlin. I haven't been to Germany before. Paris is okay but I…"

"Actually" Mara interrupted. "They're sending you, me, Dave and Bob to Rome. The bureau there spotted some Templars and they need reinforcement."

"Aren't Rome bureau has the highest number of assassins working there."

"Not anymore" Mara answered. Her face showed both concerns and distress. She was raised as an assassin. Her bond to her sisters and brothers ran deep than his. "Last month we had to pull our main force from Rome to help aid our brothers and sisters in Spain. You've completed every of your tasks perfectly since you became an assassin. They're sure to send you there now."

"I guess I'm good enough then." Tadashi chuckled lightly. Excitement flushed his body and he felt more alive than before. "When do we leave?"

"In three hours" Mara said, looking at her watch. "Bob had already started packing his things. I'm on my way to tell Dave. See you in three hours."

"Sure"

Tadashi waved at her and went straight to his room. At least he had things to do to keep him from losing his sanity.

The Assassin's Creed was ancient, as far as Tadashi could tell. The creed was created to stop another organization, the Templars. The Templars had been trying to conquer the world for hundreds of years and the Assassins would try their best to stop them. The war between the Templars and the Assassins started since the Roman era, until now. Tadashi didn't think that the war would end soon. It seemed liked the Assassins and the Templars were balancing each other. One was seeking for mighty power to control and rearrange the world, and one was seeking ways to free the captured minds.

Tadashi packed up his gears and his clothes. Everything he owned now was given from the Creed. His old life died with him in the fire.

Mara and Dave were very happy to have him joining their group while Bob and he shared a mutual respect. Their trip to Rome was quiet and peaceful. But when they arrived at Rome, the chaos began.
