A girl with a brown with long hair that's up to her waist was sleeping comfortably. Her face was so peaceful and she's smiling. Her happy dream was disturbed by the sound of alarm clock. The girl opened her eyes revealing her big hazel eyes. She yawned. She was wearing a blue pajama that was way too big for her. She looked at the alarm clock.

"HIEEEEEEE!" The girl, Tsukasa shouted. It's already 7:20. She's going to be late. She quickly got up and rushed to the bathroom. After taking a quick bath, she changed into her uniform, wore this big eye glasses that covered her hazel eyes. She was about to go down the stairs when she tripped. She fell, head first. She rubbed her face. She glanced in the kitchen. It was empty. She lives all alone in that house. Yes, she was all alone. She shook her head. She rushed outside and ran towards the school. She barely made it in time. The second she stepped inside the school ground, the bell rang. Tsukasa rushed to her classroom. While she was on her way, she saw one of her classmates. She has blue hair and pink eyes. The girl slapped one of the cowering girls.

"Don't you dare get close to Hayato and the others. They're mine only." Tsuna growled. She continued to beat up those girls. Suddenly, they heard someone shouting.

"Hime!" Gokudera shouted while running towards Tsuna. He was smiling. "What's wrong hime?" Gokudera asked.

Tsuna faked scared. "They were bullying me. They told me to not get close to you and the others." Tsuna said.

Gokudera being the loyal he was, even though Tsuna doesn't have a single bruise while the other girls are beat up, believes what Tsuna said. It was always like that. Tsuna was faking innocence in front of others but once someone did something she doesn't like, that person will surely meet hell. Tsuna was always the one favored because they believe that she's innocent. She was very famous. Every boys like her and no one dared to bully her or speak or think ill of her because of the fear to meet the wrath of the six most famous and most feared boys namely, Hibari, Mukuro, Ryohei, Yamamoto, Gokudera and Lambo. She's also rich. She also has two over protective brothers, Giotto and Dino. They were part of the mafia. Her uncle was the most famous assassin, Reborn. She also has connections with many other feared people so no one dared to mess with her. What she wants is what she gets no wonder why she became that kind of a bitch yet the others believed she kind hearted and really caring person. The one that knows the real her, those who have been bullied by her, doesn't have the courage to tell the other the truth due to the fear of being completely erased from this world.

"You'll all pay for what you did for jyuudaime." Gokudera brought out his dynamites. He don't care whether they were boys or girls as long as they did something bad to Tsuna, they will be punished.

Tsukasa sighed. She's tired of watching this happen again and again. She looked at her watch. It's already 8:00. 'The homeroom is over. I'm sure I'll get punished.' Tsukasa thought. Sure she's not a target of Tsuna's wrath but she's not favored here. Every little mistake of her is noticed and she's always punished 3 times harsher just because she's a poor student and the others were rich. She's always mistreated and treated like a slave. They called her no good-tsuka. They call her Tsuka as an abbreviation of her name Tsukasa. Tsukasa rushed to the classroom and found a furious teacher looking at her.

"Why were you late?" the teacher asked angrily.

'I see. He won't buy anything I tell him. It doesn't matter what my excuse was, I'll still be punished and 3 times much worst.' Tsukasa thought inwardly. "I woke up late." Tsukasa simply said.

The teacher became more furious. "Detention after class!" the teacher shouted.

Without saying anything, Tsukasa slowly walked towards her seat. She's used to that. She can hear the other students whispering to each other and giggling. They were saying something like, 'no good as always' or something like 'as expected of no good- Tsuka'. She sat down. After about 10 minutes, the door opened. Tsuna entered together with Gokudera and Yamamoto.

"I- I'm sorry for being late. I overslept and Gokudera and Yamamoto had to wait for me. If… if you're going to punish us for being tardy, please just punish me." Tsuna said with fake tears threatening to fall.

The teacher became nervous. "It's okay. You're a responsible person so you're excepted to detentions. I know you don't mean it." The teacher said.

'What a greedy teacher. He just wanted to have the favor of Tsuna so that he'll also have influence and he'll be respected and feared by others.' Tsukasa thought.

Tsuna looked up and smiled using her "angelic" smile. The entire boy population blushed while the girls looked in awe but of course Tsukasa didn't buy the lie. She can read Tsuna like a book.

'She's really a devil in angel's clothing. I can't believe they believed her. Even them. Why don't they notice her wrong doings? They're like a marionette that will obey what Tsuna said even if they knew it's a bad thing. I can't believe it.' She thought. She's really frustrated right now.

"You may go to your seat" the teacher said. The three returned to their seats. The classes ended without Tsukasa noticing. She's thinking about something since she already knew all the lessons being taught. She's just pretending to be no good but the truth is when it comes to ability, whether it's physical or mental, she's superior to others. She went to take her detention. Meanwhile, a mafia attacked the school when all the students except Tsuna and her guardians. When the detention was over, she was about to go home when she saw what's happening.

'What should I do? Should I help them? I don't want them to be hurt again. The enemies are too many. If this goes on, they'll lose.' Tsukasa thought. She doesn't know what to do. She has to remain unnoticed by them. She has to keep her true identity to them in order for them to be happy. They'll better without her. "I just have to keep unnoticed while I help them." Tsukasa muttered. Tsukasa began taking every man in black she encounters quietly. When the enemies are already few and she's sure that they can beat them, she went to the roof top. She watched Tsuna and her guardians or maybe only her guardians since Tsuna wasn't fighting. She's just standing watching them fight. Tsukasa saw the guardians fighting. She knew they're suffering. Though they're good at hiding it, she can see their pain. They're all beat up but in mafia world, if they show it, it will only become their weakness so they show no sign of exhaustion even though they really exhausted. She watched them with pain in her eyes. Every time she sees their serious faces, she can feel something in her heart. Her heart is getting heavier and heavier. She doesn't want them to suffer anymore. She won't let them. She will protect them no matter what. Gokudera and the others finished their last opponents. They ran toward Tsuna making sure she's alright. They were relief to know that Tsuna wasn't hurt. Gokudera and Yamamoto began their usual fight again and the same for Mukuro and Hibari. Lambo just smiled at them. Ryohei cheered while Chrome did her best to stop them from fighting.

- FLASHBACK -

Tsukasa watched while her friends bickered. They're faces was blurred. 'Even though they are always fighting, even though they are always loud and hot-headed, I love them I don't want them to change. I want them to stay like this. I know they really treat each other as friends. That's just their way of showing it.' A contented smile appeared on Tsukasa's lips. Its okay if their a bit selfish and childish. She doesn't want them to be filled with sadness and change. She still wants her childish, selfish and loyal friends not the mature, serious, and sad. She doesn't want them to carry the burden along with their duties. She doesn't want them to carry the burden of killing people.

- END OF FLASHBACK -

Her sight is getting blurred. She can't see clearly. She felt her cheeks become wet. She touched her face. She was crying. She said to herself to not cry anymore. Unknown to her, a certain arcobaleno was watching her since the start with a confused but thoughtful look in his face.

Author's note: It's confusing right? Tsuna is not the one he is in anime but there's a reason. It will be revealed in the later chapters so please just try reading it. If you're wondering if I made a mistake because Tsuna doesn't have that kind of hair and eyes, I didn't. He's not wearing contacts and wig. It's natural color. This story is mainly about Tsukasa's past and I think someone already know who Tsukasa is by reading this first chapter because it's obvious especially in the first paragraph. In this story, Tsukasa and Tsuna are 12 years old but in second year. Tsukasa is there because of her IQ but no one knew that she's 12 while Tsuna got there because of money. Gokudera and the other guardians except Ryohei, Hibari and Mukuro are 13. It means Lambo is 13 in this story. Hibari, Mukuro and Ryohei are 14. The arcobalenos are not infant they'll be in their adult form.
