Assasination class x Katekyo hitman reborn fanfic

Yellow Octopus

"Ahhhh! REBORN!" Sawada Tsunayoshi screamed. His tutor, Reborn, had told him a very shocking news. "You want me to transfer!" Tsuna looked at Reborn in disbelieve. "Yes. Now don't interrupt me when I'm speaking. You will be there for a year and your guardians will transfer there one by one so stop your shrieking." Reborn stated.

Ding dong. Went the bell. "Oh! Looks like he's here." Reborn said with an evil glint in his eyes. "Who is i-" Tsuna asked before he was cut off by a voice he dreaded to hear.

"Tsu-chan! Reborn-chan! I'm here!" Said a albino with wings who came barging into Tsuna's room. "Byakuran!" Tsuna exclaimed with his eyes wide open, shocked.

When one speaks about Byakuran, it leads to the word or two, 'parallel world' and this was waht Tsuna's H.I. was warning him about.

Reborn smirked and took a bag feom who knows where and dumped it into Tsuna's arms. He proceeds to kicking Tsuna backwards which Byakuran then created a portal that pulls Tsuna in.

"HIEEEE!" Tsuna screamed as he landed inside the blackhole and fall through the gate of the parallel world.

"Oufff" Tsuna said as he landed on his butt. A letter from above came floating down from the air as Tsuna picked it up. It read:

Dear Dame-Tsuna,
If you are reading this, it means that you made it there alive- "Wait, so I was used as a guinea pig?!"- You are now in a parallel world where the moon had became a cresent and will remain so forever. You are to attend Kunugigaoka high for your transfer school and your class is 3-E. It is all the way up the mountains so don't be shocked. Hope you won't die, Ciao
-Reborn

"EHHH?!" Tsuna shouted, shocked by Reborn's note. He took a deep breath, turn his face towards the sky and shouted, "REBORRRRN!"

Next day...
Sizzle went the frying pan. Tsuna was cooking his breakfast. Yesterday, Tsuna found the address Reborn gave him to stay but... It was a mansion! He cooked the favourite breakfast, sausage with eggs and bacon and went to school.

Tsuna found this unusual because he wouldn't wake up so early but he had came to realised that he had grown an inner Reborn.

Flasback...

"Zzz" Tsuna snored as he had been searching his house the whole night and was very exhausted. 'Wake up!' Said a squeaky voice in his brain.

"Ah! I'm up reborn, don't shoot- Eh, Reborn?" Tsuna said. He suddenly heard the voice again, 'if you don't start changing in 10 sec...' the voice said with the unheard threat.

Tsuna hurried and change and thought, Reborn finally got himself drilled into my brain... he sighed.

End flashback.

It was a tragic thing to have a Spartan tutor from hell to ne drilled in your head. It's like a speaking H.I. with threats mixed in it.

As he walked while feeling a bit lost, he bumped into a blue haired boy. "Ah! I'm sorry, are you ok?" Tsuna hurriedly asked, standing and stretching his hand for the boy to hold as support.

"I'm fine. Are you new here? I don't think I've seen you before..." the boy replied.

"Ah... I'm new here, what's your name? I'm Sawada Tsunayoshi."

"I'm Nagisa, nice to meet you!" Nagisa replied.

"I'm a bit lost, can you tell me where this place is?" Tsuna asked again.

"Oh! That's where I'm going, follow me." Nagisa answered. Tsuna nodded his head and thought, This world doesn't seem too bad.

When they reached, Tsuna was surprised by the school's size. It was one of those prestigious schools. "I guess i'm going to the counter to register, thanks for leading the way Nagisa-kun!" Tsuna thanked the bluenette.

Nagisa smiled and waved a goodbye but after Tsuna left, he frowned with his bangs covering his eyes. There goes my first friend from the upper class, he will soon be like the others, belittling E class. Ah well.

--------------->--------->Afterwards
Nagisa POV

"Settle down class. Today, we will be having a new transfer student." Koro-sensei said. It had been a day since he came into our classroom and announced that it was he who destroyed the moon. He was really very fast. Even with all of us shooting him with BB-pellets at one shot, he can still dodge them.

I wonder whether the new student is going to be a assasin.

Third person POV

As Nagisa thought, Koro-sensei invited the new transfer student in. A confused brunette stared at Koro-sensei and walked into the class.

He structure showed that he was feeble and weak. It screamed that he needed to be protected. His big doe honey brown eyes make everyone think that he is an angel.

"I'm Sawada Tsunayoshi, nice to meet you errr-" The brunette spoke in his enchanting voice... while staring at Koro-sensei. "Nufufufu, you can call me Koro-sensei like everyone does. I am the one who destroyed the moon on March and I am your homeroom teacher. You are to try to find anyway to assasinate me." The yellow octopus said. "Karasuma-sensei will brief you the rest later."

...................Silence..................

"EHHHHHHHHH!" Tsuna shouted. This must be the real reason why Reborn brought me here!

"Well let me repeat myself," Tsuna said, flustered," I am Sawada Tsunayoshi but you can call me Tsuna, I'll be in your care." Tsuna said as he bowed.

"Nufufufu, you can calm yourself quite fast. You will sit next to Nagisa-kun." Koro-sensei briefed.

Tsuna's eves lit up when he heard Nagisa's name so did Nagisa's. He waved towards him as he took a sit next to him.

"Ok, let's start lesson, guns away." Koro-sensei said. The class groaned at their failure this morning while Tsuna flinched at the word,'gun'.

This was how Tsuna met Koro-sensei.
