Alter Ego

After unconsciously beating up those bullies, Tsuna wasted no time in returning to his classroom. No one from his class, including his teacher, asked why. It was a usual thing after all. It's no wonder why he was late; it's because he's always no good in whatever he do.

Plus, his classmates have a good idea on as to why he was late, it was probably because of those merciless bullies. But something at the back of their mind can't help but be suspicious on why dame-Tsuna hasn't a single scratch or bruise on his face or body?

It couldn't be because he defeated them. It's unthinkable. Never in a million years would that be true. So they just came to the conclusion that, it must be because of their Discipline committee. Maybe Hibari-San had caught the bullies red handed at their unforgivable actions. But if that was the case, then where are they?

His classmates immediately dismissed the thought, when did they started mingling their affairs with Dame-Tsuna? They shouldn't care on what happen to him.

Soon, his classmates focus their attention to the boring lecture of the teacher and the brunet quietly walked up to his chair.

Tsuna was sitting at the back near the window, his chin resting in his palm and his gaze far across the scene behind the window. His mind couldn't erase the memory of seeing those bullies in those type of situation. It was just so impossible. He clearly knows his capabilities so it's no way possible that their horrible state is caused by him. But, it could only be him, after all he is only the person staying there.

But if it is indeed him, why is it he doesn't have the memory of doing that? And how in the world did he do it? He doesn't know any skills and techniques that could possibly beat them. Heck, he doesn't even stood a chance in landing a hit on their gang leader.

He closed his eyes, maybe if he calms and relaxes his mind he will somehow remember.

"I've had enough of this."
"Damn you, dame-Tsuna"
"Tsk, I missed."
"M-Monster!"

He abruptly opened his beautiful caramel brown eyes. Mixed emotions that flashed in his eyes. Shock, guilt then fear. He was really taken a back of what he remembered and he felt guilty of what he did. But the emotion that he he felt greatly was fear, j-just who in the world was the person that beat them?

I-is it possible that I-it could be the malicious voice that spoke to him?

He bit the inside of his cheeks, trying to suppressed the the fear inside of him.

H-how is it possible for someone to be that strong and cruel? And to think that someone is i side of his head. W-what will happen if that voice suddenly took over him and did it again? What if next time, he doesn't even remember? Or what if he will forever manipulate his body? What if he wil-

"Stop overthinking, idiot."

With that simple sentence, the brunet's jumbled thoughts was immediately put to a stop.

What the brunet didn't know was that, he balled his fist, making his fingernails dig in to his right palm and he was starting to tremble. But with just that sentence, the voice managed to compose Tsuna's composure.

"If I was planning of taking your body, I would have done it years ago. And didn't I tell you before that I only defeated them for the sake of protecting you?" He could hear the voice sigh exasperatedly, "Do I have to spell that out for you, da-me Tsu-na?"

Tsuna was quiet for a while before the corner of his mouth tugged upward to a smile, he shyly mumbled in reply, "..no,"

"Hm, good. Don't overwork yourself for something stupid, it makes you even more pathetic, got it?"

"H-hai." Tsuna stuttered. He didn't expect the voice to be this kind to him. An sudden idea came to his mind before he hesitantly asked,

"B-by the way, do you p-possible have a n-name?"

The voice didn't reply.

"A-ah, I guess you don't ha-"

"Natsu."

"W-wha?"

The voice sighed yet again and repeated, "Natsu. That's my name."

"O-oh, it's beautiful."

"..Thanks" Maybe it was Tsuna's imagination but doesn't the voice seemed kind of flustered? As if, he was surprised and embarrassed of getting his name complimented? 'Nah, that's just impossible. Dont delude yourself Tsuna.'

And with that, Tsuna didn't think any further and tried his best to listen and take down notes from his teacher. Having the voice -no, Natsu, said that to him really did reassure him. Now he can finally be at ease.
