Tsuna's secret

The sky is cursed

After the incident involving Hibari, Reborn didn't dare mess with Tsuna or Hibari and he only watched them from a distance as he (unsuccessfully) trained Ieyasu to be the Vongola boss. Ieyasu had a bad attitude and no guardians, and the guardians Reborn set him up with were all rejected. Some even joined Tsuna who took them in with kindness and no question. Reborn was starting to think that Iemitsu chose the wrong son, A few minutes later his thoughts were correct as nothing happened when he shot Ieyasu with the dying will bullet.

"Uh is he okay?" Yamamoto asked, staring at the seemingly dead Ieyasu on the ground.

"*sigh* He'll be up in a minute, also Reborn please don't do that again." Tsuna said, giving Reborn a hard stare.

"Why-?"

"REBORN! I will kill Tsuna with my dying will!!!!" Ieyasu shouted jumping up with a severely tainted sky flame on his forehead and charging towards Tsuna who stopped him with a finger on his forehead. Ieyasu kept failing his arms around trying to hit Tsuna while everyone else stared in confusion.

"Reborn can I borrow Leon?" Tsuna asked and Reborn handed him the chameleon. Leon changed into the ten ton reversal hammer and Tsuna brought it down on Ieyasu's head, knocking him out and extinguishing the flame.

"As for your earlier question and the reason why the sky flame is so tainted is that he's cursed." Tsuna said.

"Why is he cursed?" Reborn asked and Tsuna sighed.

"You should know who after all that pacifier..." He trailed off but Reborn understood.

"Ok I get it but how can I train him to become Decimo at this rate?" Reborn questioned.

"Just give him the lessons, he will be reunited with his guardians on his own. Once that happens we can start on removing the curse, he will learn everything you teach him now but he is trapped in his mind so it won't show until we get rid of the curse." Tsuna explained and Reborn sighed.

"I guess I can't make you Decimo instead then." Reborn stated disappointedly.

"No, after all I have my own Famigila and most of them don't take kindly to humans." Tsuna stated before leaving. Reborn had a million questions just from that statement but he knew he wasn't going to get an answer so he solemnly kicked his student awake.

"What happened!?!" Ieyasu screeched when he woke up.

"Training incident." Was what Reborn said before pulling him into another training session. Tsuna smiled sadly before vanishing before Reborn's eyes.

'...' Reborn had nothing to say to that as he pulled down his fedora and turned his attention to the idiot in front of him.
