A/N: Okay, I've been wondering for a while, and I don't know if there is a story out there since I rarely scans all the stories in the archive of KHR, about the tenth generation being the parents of the first generation! So here is some short one shots (or stories, depending on the mood). So I hope you like this one!

Chapter 1: I want a pet!

Sawada Tsunayoshi, or Tsuna as how his friends tend to call him, is your average college professor that has Botany as his major subject and belongs to the department of College of Science in Trinisette Academy. His subject needs a lot of explanation and some of his co-workers are out of this world.

For example, Verde their chemist professor doesn't care about his students actually. He just wants a success in each experiment and if a student manages to gain his interest…well…let's pray for that poor soul whoever it will be.

Another chemist teacher is Gokudera Hayato, one of Tsuna's best friend, he is temperamental and will throw bombs if he gets angry or one learner manage to irritate him. But when it comes to Tsuna, Hayato become a total different person. A obedient one if you will say.

Their mathematician and computer experts were what you call 'opposites do attract'. It's not in a romantic way but in a friendship way, Shoichi Irie and Spanner.

Shoichi is friendly but gets stomach ache when he was really nervous. He is a genius but sometimes has a low self confidence and during those times Spanner comes to the rescue.

Spanner is very quiet and anti social to a point. No one knows how Shoichi manage to befriend him but the blond really likes his company especially when they debate about certain principles. Tsuna remembers one time when he freaked out when he saw a robot cleaning their faculty. He found out the Spanner created it with the help of a certain red hair in building it.

Another person that can send you to the point of hysteria was the two terror Physics professors, Byakuran and Reborn. Now this two are like magnets of the same side that causes them to repel each other. In other words they hate the presence of one another. Byakuran, the marshmallow lover, always wear a smirk and tends to be kind and cruel at the same time. Reborn…well… he is just a pure sadist. See? They repel each other because they were so alike.

Enough about the teachers and let's go back to our real subject in hand in here shall we?

Now Sawada Tsunayoshi is a single father of a five year old son. Giotto, his little angel, is very adorable, kind and everything you could asked for a child…though he can easily be scared and a bit of clumsy…well that could be attributed to his father.

Speaking of the said child…

"Tenth, aren't you going to pick up Giotto?" Gokudera asked as he leaned on his chair backward in order to see the face of his friend beside him.

Just in time Tsuna gaze up on the clock that is hanging on the wall of his right side and true enough it was time of the children to go home. He saved the file he was currently working with about the next test of his students on Meristems and Ground Tissues of the plants.

"Thanks for reminding me Gokudera" Tsuna smiled at him and Hayato returned the gesture.

"No problem Tenth, I'm going to pick up also my own brat." Gokudera muttered the last part and had Tsuna laughed wakwardly. He does not know it why but all of his friends were single fathers just like him.

"Then shall we?" with that they leave the academy and head to the pre-school just a few blocks away from their work.

Just what they expect the school is full of littering kids running towards their parents. Some are chatting while some are playing. He looked around trying to see his son but a sudden tackle made him to fall on the ground.

"Ugh…" was all he muttered as he tried to regain his balanced but didn't manage it as a little bundle clung on his waist.

"Papa!" the little child exclaimed with a sunshine smile.

"Giotto," Tsuna smiled back, "Don't tackle me next time, okay?" he slightly scold the little blond.

"Okay!" Giotto beamed and made his father to sigh, there was no way his son will stop in tackling him.

"Well…we will go ahead first Gokudera-kun." Tsuna said to his friend.

"No problem, Tenth!" Hayato gave him a thumb up. "I'll wait for my own brat."

"Uncle Hayato! G is talking to the teacher right now!" Giotto said with a smile, not understanding what was the meaning inside his sentence.

"That brat…" a dark scowl appeared on Hayato's face as he walked inside the school, "What did he do this time?"

Tsuna sweat drop a little.

"Let's go shall we?" Tsuna clasped Giotto's hand.

The way home was not spend in silence.

"Papa…"

"Hmm?"

"I want a pet." Giotto brought the topic suddenly.

"Eh?" Tsuna think about it for a moment, "Sure, what do you want? A dog?"

Giotto shook his head.

"No? Perhaps a cat?" he asked again.

Another shook of his head.

"A…bird?"

A third motion of no was made.

"Then what do you want?"

Giotto smiled happily at him.

But then…

"I want a pet LION Papa!"

Tsuna stood frozen right on the spot…. Where did Giotto pick up this weird habits of his?

A/N: Don't know! I just made this out of the blue :D !
