Chapter 1: Watching Over You

Hiro's eyes fluttered open as the rays of sunlight entered his room telling him to wake up and get on with the day. He wanted more than anything to go back to sleep, but the day had other plans for him. He groggily rubbed his eyes and got out of bed, getting ready to just get on with the day. He approached his best friend's charging case.

"Good morning Baymax." He patted the top of the charging case and continued to get ready.

There was however, another person in the room. A person who Hiro didn't say good morning to because he wasn't even aware that the person was in the room. Tadashi sighed and smiled. "Good morning Otouto."

Hiro hadn't heard what his older brother had said because it wasn't exactly easy to communicate living in two different planes of existence. While Hiro was alive and well, Tadashi on the other hand, was a ghost. After he ran inside the flaming building, it exploded and he lost his life in it. Every day since then, Tadashi has been doing his best to look after Hiro and make sure that he didn't get into any trouble.

It was really hard at first for Hiro to cope with Tadashi's death and it was even harder for him to watch his little brother suffer because of a stupid mistake he had made. But with the help of Baymax and the rest of their friends, he was able to move on. Little did he know though, Tadashi never really left. He was just there in spirit form. He didn't really have anything better to do than to watch over Hiro, but even if he did, he would probably continue watching over him anyways.

After a while, the oldest brother had gotten used to Hiro not being able to see or hear him. As long as he was there to protect him, then it would be just fine. Of course he still wished that he could talk to him sometimes. Hiro had finished getting ready and approached the sleeping Baymax again.

"See you later buddy, I'll be back and maybe we could hang out later."

The prodigy gave the sleeping robot a smile and left the room. Tadashi couldn't help but smile.

"Hey knucklehead, wait for me."

The ghost stood up and followed his brother out of the room. Hiro could be a handful at times but at least now he could make sure he didn't do anything stupid, because he knew what his little brother was capable of. The good thing was that he hasn't gone bot fighting since the fire, so that was good. He did occasionally get into some trouble though and it was always Tadashi that secretly got him out of it, he just didn't know it.

Hiro walked out the door of the cafe with a quick goodbye to Aunt Cass. Tadashi gave his Aunt Cass a goodbye as well even though he knew she couldn't hear him. He followed Hiro as he walked down the sidewalk to an unspecified location. It didn't matter where he was going because Tadashi would always be with him. He just wished that Hiro knew how true that actually was.

Tadashi followed Hiro to a candy store, one they used to go to a lot before the fire. While inside, Hiro purchased some gummy bears as he always did. Years later, Tadashi still could not understand what was up with that kid and gummy bears.

While at the candy store, Tadashi noticed that Hiro also bought some vanilla covered nuts, his favorite. Hiro was allergic, so why would he go through all this trouble to buy nuts? Specifically Tadashi's favorite? Oh well, he would probably find out sooner or later.

The brothers walked out of the store, one behind the other and soon, Tadashi was following his brother into that stuffed animal store that specialized in making stuffed animals of people's design. Weird, Hiro went into the store the other day to have a stuffed animal made, but Tadashi never got a chance to see what it was.

"Uh, i'm here to pick up an order for Hamada."

The man at the front started looking behind the counter and pulled out a nice looking white box. "Here you go." Hiro pulled some money out of his pocket. He placed it on the counter and left with the box. Tadashi wondered what could possibly inside. Maybe Hiro liked a girl and he wanted to impress her with a stuffed animal. It was a possibility, but Tadashi didn't know for sure.

They eventually made it back to the cafe. Tadashi followed Hiro up the stairs back into their bedroom. "Ow." Within seconds, the giant adorable marshmallow robot activated and inflated to his full height. "Hello Hiro, are you in distress?"

"No Baymax, but, I got it." Hiro held the box up to show the robot. Now Tadashi could finally find out what was inside. Hiro sat the box on the floor, and once he opened it, he pulled out a cute stuffed Baymax about the size of an average teddy bear. Tadashi raised an eyebrow as he wondered what he could possibly need it for. Baymax blinked.

"Are you going to go tomorrow?" The robot asked.

"Uh, yeah, because, tomorrow is pretty special."

Go where? Why is tomorrow so special? Was is someone's birthday? Was it Christmas? No, that was a couple of months ago. What would possibly make tomorrow so special? Tadashi approached the calender and saw that tomorrow's date was circled with a big heart.

"February 14th. Valentine's Day."

That explained the candies and the stuffed Baymax, but who were they for? Tadashi figured that if Hiro did have a crush, then he would just have to be there to guide him through it.

Later that night, Hiro was getting ready for bed. He kept getting a lot sleepier lately, which was probably due to him not getting enough sleep in the first place. And of course, Tadashi would be watching over him while he slept, like he did every night. Even though he was a ghost, he could still sleep, he just preferred to look after Hiro while he slept since he didn't need sleep to run on anymore.

He knew that Hiro could be an absolute menace during the day, but while he slept, he just looked so peaceful. "Alright Aunt Cass, i'm going to bed now." Tadashi could hear Hiro call from all the way downstairs. Hiro opened up the door and continued to remain completely oblivious of Tadashi's presence. He turned and noticed that Baymax was still activated.

"Well, I've got a big day tomorrow so I guess i'd better get some sleep."

"I agree. Resting will help better improve your chances of attention and focus."

"Yeah, you always know what's best buddy." Hiro yawned, indicating that he was tired. "Well, good night Baymax. I'll see you in the morning."

"Good night Hiro." Baymax looked in Tadashi's direction for a few seconds before retreating into his charging case. The younger brother stretched his arms out, then slid underneath his covers.

Tadashi smiled. "Good night, bonehead." He bent down and gave him a kiss on the forehead and watched as the prodigy drifted off to sleep. Tadashi just thought that he looked so adorable while he slept.

When they were younger, Hiro would ask to sleep with him all the time, especially after he had nightmares. But then Hiro got older and they didn't really do it much anymore. Hiro really regretted it because now Tadashi was gone. Not entirely of course.

Tadashi smiled as he started stroking his brother's wild hair. Ruffling it always gave him great joy that he couldn't really explain. He often ruffled Hiro's hair for two reasons. One, it made him feel good inside, and two because it really annoyed Hiro. Maybe the second reason was the cause for the first reason. Tadashi never thought much about it, he just did it.

Hiro started mumbling something in his sleep. It sounded something like "Tadashi...stop...touching hair..." The older brother's smile grew wider.

"Good night Hiro. I love you."

Tadashi gave him another kiss on the cheek and continued to stroke him as he was already drifting inside his sleep.
