"Okay, class.  That's it for school!  Have fun on your summer break!"
"YEEEAAAAAAAH!"
Tsuna sweatdropped slightly as he watched his students stampede out of his classroom; he heard a chuckle at his shoulder.
"Kids will be kids, Dame-Tsuna.  I bet you were like that when summer break came."
Tsuna gave an amused smile to the infant on his shoulder.
"Happy?  Yes.  But I didn't stampede out of the classroom like a herd of bulls."
Reborn tipped his fedora upwards and smirked.
"You ready?"
Tsuna ran a hand through his hair before giving a devilish smirk of his own.
"Ready as I'll ever be, Reborn."
~~
"Hieee....Reborn said he's gonna put us through hell in the next two months with training!"
"Don't worry, Juudaime!  I'll be there to support you!"
"Maa, don't forget about me!"
"Shut up, baseball-idiot!"
"Hahahaha!"
"G-Gokudera-kun!  Y-Yamamoto-kun!"
Three teens were happily chatting away in the Tachibana Household--Hayato yelling, Takeshi laughing, and Takehito panicking.
Ding-dong...
Hito blinked his eyes in surprise before stumbling out of the living room, heading towards the door.
'Wonder who it could be...Reborn always appears randomly, so it can't be him...'
Hito opened the door.
There, at the entrance, stood one brunet adult, waving merrily to the blonde teen.
Reborn was perched on the adult's shoulder, smirking mischievously.
"Konichiwa, Hito-kun!  May I come in?"
~~
Tsuna smiled cheerfully as he sipped the cup of green tea in his hands.
Hayato gave a suspicious scowl, Takeshi continued to smile brightly, and Hito fidgeted in his seat.
"S-Sawada-Sensei...why are you here?"
Tsuna blinked his eyes before tilting his head in Reborn's direction.
"Reborn invited me over."
Hito gapped and flickered his gaze to the smirking baby hitman.
"...D-Did he threaten you?"
"No~he only invited me over."
Suddenly, Hito felt wary of Tsuna--like the brunet had suddenly became another Reborn.
'Uwaaaaah!  What's this bad feeling I'm getting?!'
"Eh~?  You have a good Hyper Intuition."
Hito jolted out of his thoughts and looked at Tsuna with surprise.
"H-How--!?"
"Gomenasai, Hito-kun, but I should properly introduce myself to you now."
The brunet set his cup of tea down.
"I am an assassin," It wasn't a total lie--Tsuna had taken a few assassin missions before.
"And I'll be helping Reborn in tutoring you."
Thump!
Ah...poor Hito fainted.
