Inintionaly, Reborn was eager to tormen-oh he meant tutor his new student in subjects. 

But right now, he didn't know whether to be impressed or irritated..

Because Tsuna seemed to be aceing every question he threw at her. Right now he was trying to stump her at Pre-Algebra.

R: 2n + 9 =25?

T: 8

R: -2x + 1 = 5?

T: -2

R:-7 - 8d =17?

T: -3. .......Are you sure your eye is ok? It's twitching.

Reborn had dynamite in the room, for a question she would get wrong. But he didn't have her stumped. Even if he didn't show it, he would be pouting that her brain was taking the fun out of this.

"Reborn? There's a kid on the tree outside." Tsuna got his attention.

"Ignore him." Reborn quickly quipped as he gathered the dynamite to be put away, and silently thought of how to train her since she finished their study section earlier than he thought. 

"Here I am, Reborn! It's me Lambo!" A five-year-old boy in a cow print suit yelled only to be ignored by the hitman. Tsuna on the other hand decided to intervene before things went too far. 

"Hello, I'm Tsuna, you said you're Lambo right?" she asked picking the child up.

Lambo was quickly taken with Tsuna as she let him play with her and ignoring Reborn. 

----------------------------

The next day Tsuna had to head over the school to teach the cooking club how to make treacle tarts. But on the way, she encountered a pink-haired woman on a mommy bike. 

Her 'alarm bell' went off again. This woman's dangerous.

The point was further proven when the woman apparently poisoned a can of soda to kill her. 

"Jyuu-hime, is something wrong?" Hayato asked as he, Takashi and Tsuna were all on the rooftop as they were having lunch.

"Well, a woman nearly tried to kill me with poisoned soda-" Tsuna started as she sat down then Hayato looked frightened all of a sudden.

"Did she have pink hair, and looked foreign?!" He franticly asked.

"Yes, do you know her?" Tsuna asked.

"He does. And I do too." Reborn said from out of nowhere. "And I know you're there. Come out, Bianchi." Reborn said to a nearby door.

And as Tsuna thought, it was the woman from before.

"Sis!" Hayato said before he crumpled to the floor.

'Wait. Sister? Not that I get a better look, they have the same eyes and somewhat similar bone structure in the face.' Tsuna thought.

 "Reborn! I've come to take you back Reborn. This is no place for you. The dark, dangerous, and thrilling realm of the underworld is where you belong." 'Bianchi' said with a blush. 

"I told you Bianchi, I have a job of raising Tsuna. I can't disobey the Ninth's request." Reborn said simply.

"Poor Reborn! If she doesn't die in an accident, Reborn will never be free!" Bianchi whined in despair, pointing accusingly at Tsuna.

'I knew it. She tried to kill me to get Reborn, or she may even think I'm stealing him.' 

Bianchi then left saying she would come back for him if Tsuna died.

In the infirmary, Hayato confessed that he had a deep-seated fear of his own sister since he was six when she baked cookies for him. But it was at that time she gained the ability to do poison cooking which pretty self-explanatory. He also gave a piano recital, but people commented that it was excellent and ever since, his father had him eat Bianchi's cookies before every recital. 

Tsuna looked with a deadpan look and said; "Hayato, didn't you ever think that maybe they just said that so they didn't earn your dad's wrath or something? He's a mafia boss too, right?" From the look on Hayato's face, he didn't.

Then she turned to Reborn. "What about you?"

"Bianchi's a fellow hitman. A freelancer if you may. She's known as 'Poison Scorpian' Bianchi. She's also my fourth lover." Reborn plainly said, even holding up 4 fingers.

".....I don't even want to know how that happens." 'Even if he's a man-child.' 

---------------------------------------------------------

Then her 'alarm bell' went off as she saw Bianchi in the school on the way to the cooking class. She was going to sabotage the cakes being made in there!

Quickly, Tsuna jumped Bianchi by stopping her, but she unconsciously her magic had the door kept lock to not let Bianchi in, but would let the others out when they are done.

"Bianchi. Mind if I have a talk with you? Alone?" Tsuna requested in a firm, and slightly angry tone. 

The female assassin flinched at this change in the girl's attitude. She did know that the newest student was a female and thought that Reborn would get seduced by her. But she didn't count on the girl being a Sky.

"I know you came all the way to kill me but. You do know what would happen if you did? Reborn's contract would've been breached and he would have to answer to it. His rep would have gotten a big blotch. No one would be able to trust him if you killed off the last Vongola heir. Not only that, you would be putting your father and your Familiga in danger and making an enemy out of all of Vongola's allies. And there's a chance that your poison cooking will be useless against those who know ways around it. Not even Vendicare would spare any mercy. Did you even think about these sorts of consequences?" Tsuna said, not even knowing that some sky flame aura was coming out of her, her green eyes glinting with an orange tint.

Bianchi never felt this intimidated in her career as a hitman and felt she had to back down. She didn't even consider how Reborn's rep would've been ruined because of her. Plus it would've wrecked her family's alliance with Vongola, and she would've gotten a one-way ticket to Vendicare. Not even Reborn could've saved her from them.

From a nearby hiding place, Reborn smirked. His student was exceeding far better than he thought. Who knows, maybe his job will be over before he knows it.

-------------------------------------------------

Although, Bianchi decided she would be better off sticking around for Reborn, plus she even offered to teach Tsuna cooking and art, much to Hayato's dismay. (Though Tsuna politely refused. She didn't want to poison her favorite treacle tart.

Tsuna had a feeling that more will be coming along the way.

---------------------------------------------------

I know that people are asking for some unusual pairings, and I had a friend that said she thinks that Verde should get Tsuna. They said that the scientist doesn't get enough love and that he would be over the moon if he learned that magic is real and the two of them would bond over learning about magic and tech from the other and how to improve it. 

Then another friend said it should be Skull, because they would bond over being an underdog, or not dying when they should've.

Then there's the subject of Xanxus, and the two of them could bond over being adopted and not knowing about it for a long time, despite their different ways of handling it. Xanxus being frozen by the Ninth, and Tsuna knowing her adoptive parents died for her to live on.

Anyone else want to share their idea of a pairing before I decide? It will take a while though, so plz comment and tell me why this pairing could work!

Thank you all and stay safe during these tough times!
