No matter where we went, Shigeru shone like a beacon, and I was hidden in his shadow, overlooked by everyone else. It used to hurt, but I've gotten used to it. I know what people think of me. Just because I'm a girl, they don't say it to my face, but I know what they really think of me anyway. I can see it in their eyes when they look at me. They call me "dame-Tsuna", because in comparison to my brilliant brother, I wasn't anything. And I knew that.

Chapter 1.

"Tsu-chan, you came home in the middle of class again," Mom chided. "That's not nice."

Tsuna hummed nonchalantly.

"I'm not saying that you have to get into a top college, but you should live a life with more...hmmm... fulfilment! You could learn to be more like your brother."

The bushy haired girl let out an inaudible sigh.

"…but Shi-kun's grades haven't been looking very good lately…"

There she goes again, Tsuna thought. She had long learned to tune out her mother's voice especially when she was rambling about her twin. Her mother was always happy to talk about Shigeru, and all Tsuna had to do was listen, or at least she pretended to. It was better that her mother was talking about Shigeru than missing Dad.

"…there was this interesting flyer in the mailbox…"

Now, where did Mom keep those chocolates? Tsuna rummaged gently through the contents of her fridge. Ah, there they are.

"…and a home tutor's coming today!"

Tsuna looked up and almost dropped the packet of chocolates. That took her by surprise. She shut the the fridge and turned to look at her mother.

"The flyer promised to 'raise your kid to become the new leader of the next generation'! Doesn't it sound great!" Nana's face was just shining with excitement.

It sounds like a scam, Tsuna glanced worriedly at the flyer in her mother's hands. Her mother could be quite gullible sometimes.

Then, the door clicked open, and her bushy-haired brother breezed in.

"I'm home!" He yelled, and shook off his shoes.

"Oh, Shi-chan, aren't you early!" Nana waved with the flyer she was holding. "I was just telling Tsu-chan that I called a home tutor today."

"Say Mom," her brother went on, as though Nana had not said anything, "what's this kid doing here?"

Tsuna peered over her mother's shoulder. Sure enough, there was a little kid in their house. No, he wasn't just a kid, he was a baby, and he even had a pacifier around his neck. No matter what, the kid was definitely a baby, he had the dewy skin of babies, and their huge round eyes. But why didn't he feel like a baby? He was standing so confidently, holding a mini suitcase, dressed in a black suit and even wearing a fedora hat, as though he were an adult. Something's off about this baby.

"Ciaossu!" He greeted in a high preppy voice. He tilted his head up to look at Shigeru, then turned his gaze to her.

Tsuna immediately lowered her gaze to the floor and slowly inched back to the kitchen. Her skin was feeling all tingly. She could still feel the baby's gaze on her. What is with that baby? Then he spoke, not blubbering nonsense like anyone would expect from a regular baby. His words came out in a perfectly intelligent manner. To say Tsuna felt mildly disturbed, would not be accurate. She was definitely more than mildly disturbed.

"I arrived 3 hours early, but as a service, I'll evaluate you now," the baby was saying. "My name is Reborn, the home tutor."

Shigeru burst out laughing, "What is this kid saying!"

"So you're Shigeru," the baby said. Tsuna heard a yell, and when looked up, Shigeru was rolling on the floor grabbing his knee. Nana just stood there looking stunned, and they could only watch as Reborn began to drag her brother up the stairs.

"That hurt dammit! Don't think I would forgive you so easily just because you're a baby!" She heard Shigeru yell. A loud thud followed. Mom's eyes grew as wide as saucers, but other than that, she seemed to have frozen.

Then, her mother broke into a wide smile. "Isn't that lovely? They're getting along wonderfully," she said and went back to washing the dishes. "Trust your brother to be so good with handling children too."

Tsuna just stared at the back of her mother, then she heard another thud from upstairs and winced. She had better check on her brother.

Tsuna's hand paused just an inch from the door of her brother's room. She just heard something strange. Something about the Mafia. What was she doing? Curiosity got the better of her. She should not poke her nose into other people's business. This Reborn obviously had no business with her. Like everyone else, he wanted her brother. And like always, she should fade into the background, where she belonged. Her brother would be fine, he always was. Besides, this could be some practical joke, after all, how could a baby possibly be a tutor?

He'll be gone by tomorrow, and it'll be like nothing ever happened. Maybe Mom will learn a lesson and stop trusting such weird flyers.

"Good Morning Tsu-chan!"

Tsuna yawned in response, she hardly slept last night, dreaming dream after dream about strange babies, about men dressed in black with guns, and about fedora hats with legs and tails. Yes, she was weird like that.

"Ciaossu!"

Tsuna froze. The baby was still here, and he was staring at her. She nodded nervously to the baby, quickly wolfed down her toast, and dashed out.

Normally, Tsuna liked babies just fine. They were cute, they were innocent and they usually liked her. Tsuna was only afraid of babies when they start crying, which was the same as most people. That baby at home though, is on a completely different scale.

When is he going to go home? Won't his mom worry? She thought, as she walked along the familiar path to school.

Tsuna loved the walk to school, it gave her time to collect her thoughts. It was the only time when she was completely alone. At home, her mother would always be around. Moreovoer, now that the baby was there, she definitely could not feel at ease. In school, she got so self-conscious, it was suffocating. If only she could be more confident of herself. If only she could be like Sasagawa Kyoko, the prettiest girl in her class.

Sasagawa Kyoko was practically the perfect girl. She was pretty, smart, athletic and everyone liked her. Even her brother liked Sasagawa Kyoko, and he was the kind of guy that used to have only two loves in his life – food and soccer. He was the kind of guy that would wake up at 4.30am in the morning for soccer practice (like he probably did today), and stay up to 3am or some other insane hour, to catch the world cup. Before Sasagawa Kyoko, Shigeru never expressed any interest in girls.

It was only a matter of time before they get together. In fact, the whole school was just waiting for it to happen. Tsuna knew that everyone thought her brother and Sasagawa Kyoko would look like an adorable couple, some even labelled them "the perfect couple". Off course, some people think Sasagawa Kyoko would look cute with Yamamoto-kun too, or maybe even cuter. In her opinion, Yamamoto-kun is definitely cuter than her brother.

"Ciaossu!"

Tsuna yelped in surprise, the baby was behind her. The baby had followed her! Tsuna stared at the baby, Doesn't he have school?

"Since you're Shigeru's twin, I decided to explain a few things to you," the baby said, "there are some things you should know."

Frankly speaking, even though she heard him speak yesterday, Tsuna still could not get used to the fact that a baby was talking to her with such perfect grammar and with such a commanding tone. If his voice were not so high-pitched, she would have mistaken him for an adult!

"I'm here to trai- "

WAIT, was that Sasagawa Kyoko? With Shigeru? Tsuna scrambled back a few steps and hurriedly hid behind a tree. Discreetly, she peered around the tree, sure enough, it was her brother, and he was walking Sasagawa Kyoko to school. They did look pretty sweet together, there is going to be such a fuss in school later. Maybe she could skip school today amidst all the drama?

"Kyaaa~ How cute!" Tsuna's forehead smacked against the tree; she left the baby back there.

"Ciaossu." Sasagawa Kyoko had crouched down and was talking to the baby.

"Why are you wearing a suit?" That, was honestly a very good question. It was summer, it had to be pure torture for anyone, much less a baby, to wear a suit in this heat.

"Because I'm in the mafia." Tsuna banged her head against the tree again, say what?

"How cool!" Sasagawa Kyoko gave a cute giggle, and Tsuna noticed her brother unabashedly staring at the pretty brunette. "Well, we have to go to school now, bye-bye!"

Tsuna waited until they turned around the next corner, before she came out of her hiding spot. Crap, she was going to be late for school, maybe she should just skip. After all, no one would probably notice her absence. With that decided, she turned around..

"Isn't school that way?"

Her feet jolted to a stop. Seriously, she should stop forgetting about the baby. She turned around and looked at him. He just looked back at her. His eyes unblinking, and so serious. His gaze was too serious for a little baby. Tsuna sighed, she hated confrontation, even if it was just with a baby. So she turned back and shuffled towards the direction of Namimori Junior High.
