Guardians undercover(Katekyo Hitman Reborn FanFic)

Chapter 1: Failed Experiment.

After what Reborn said Tsuna's head started to hurt a little bit more, but then as fast as it came it went away.

Once close to the school Tsuna slowly made his way over to Hibari to tell him to come over which almost ended up in getting bitten to death. Hibari agreed to come, because he wanted to fight the infant. As Tsuna walked away Hibari gave a small smile.

Tsuna, Gokudera, and Yamamoto made it to class just in time as the bell rang. Before going to their seats, Tsuna walked over to Chrome, and told her to come over. The same was told to Enma.

As the hours passed in class Tsuna tried to pay attention, but eventually gave up. Gokudera as usual just sat there with his feet up on his desk not paying attention. Yamamoto was sleeping.

After a long wait it was finally time for lunch, Tsuna Gokudera, Yamamoto, Chrome, and Enma all left the class to go look for Ryohei.

"Onii-san can you come over to my place after school?"

"Hmmm... I'LL EXTREMLY BE THERE. BUT I'LL PROBABLY NEED TO BRING KYOKO."

"Onii-san you can't bring her."

"WHY NOT SAWADA?"

"Reborn-san told us to only bring all the guardians. So of course it has to do with something mafia related stupid turf-top."

Rrohei said nothing for a while, "Okay... I'll ask Kyoko to go to Hana's house." Ryohei said in a serious low voice, which really shocked everyone since Ryohei was usualy never really this quiet.

"Boss, Mukuro-sama said he's coming." Chrome broke the silence.

Enma and Tsuna still couldn't really get over the fact that Chrome and Mukuro had some mental link to one another.

Tsuna nodded then began to unwrap his bento, which everyone followed suit too.

~After Lunch (Back in class)~

As Tsuna yawned, Nezu walked in and looked at the class, well more like glared at Tsuna and his friends.

Nezu cleared his throat, "As you all know tomorrow we will be having a math test. I know that you, well most of you will do perfectly well. But as a reminder those who do not pass the test will have to take supplementary classes."

Half of the class groaned. Tsuna paled knowing that he himself would be one of the unlucky ones to have to take supplementary classes. Even though he has gotten much better at his studies, Tsuna still had some troubles with his subjects especially math.

'If I fail Reborn's going to seriously kill me!' Tsuna mentally screamed, 'I wish Reborn has to go back to Italy just for now. Please, please.'

As if lady luck hated him, right after having his mental breakdown the door opened to reveal the last person that Tsuna had ever wanted to see as of this moment. Reborn, dressed in his Professor Borin costume.

Nezu turned to glare at the person who dared to interrupt his class, but his attitude took a complete 180 once he saw who it was.

"H-how may I help you Borin-sensei?" Nezu walked over to the small professor.

Borin coughed a bit, "It is to my understanding that you will be having a test soon. Correct."

"Yes."

"Very well. There are a select few who have been chosen from this class to be tutored by me for the time being. And will be excused from taking the test. I have already gotten permission from the principle as well."
