Chapter 0: The Dream

Tsuna was in a cavern of some kind, he knew this because the walls, the ceiling, and the floor were all dirt and rock. He also noted that he was not alone seeing a crowd of about one hundred veiled priests with bell ended staffs behind him and an empty aisle in the middle. He also saw his twin in front of him lying down on a six foot long slab of solid rock. "…K…ill…me…," said Giotto, Tsuna's identical twin, as he pulled Tsuna's hands down and wrapped them around his neck. He refused to actually follow through with his twin's wishes and struggled against him, resulting in Giotto being on top of Tsuna strangling him. Tsuna awoke with a start, this being the second time he had that dream this week. "I always wake up right before I get killed."

"Did you have that dream again?" Giotto asked looking at his brother who nodded at him. "I had the same dream. I wonder why we keep having that dream. Maybe we should go ask Sae what it's all about, she might know after all."

"I agree," said Tsuna as he started to look up directions on how to get to the forest in the Minakami area, which was not to far from Namimori Middle. "It's been so long since we last saw her. I wonder how she has been doing these past few months. She did say she wanted to see us again before August when she would become a "Crimson Butterfly", whatever that means."

"I personally think she is slightly insane but that's just me," said a chuckling Giotto. As he packed up his stuff expecting to stay a couple days, knowing Tsuna liked staying over when he could. "I wonder how Yae has been doing?"

"Hiiiiiiiiii!" Tsuna squealed as he was jolted from his thoughts by a knocking at the front door. Giotto chuckled as he went to get the door. Tsuna's such a chicken, Giotto thought to himself.

"HELP! It's Sae, she is in trouble! I don't know what to do!" cried Yae, as she flung herself towards Giotto.

"What did she do this time?" Tsuna asked.

"She wants to go through with the ritual but I can't do it! I tried to talk her out of it, but nothing I say seems to have any effect on her," Yae sobbed.

"What ritual are you talking about?" Giotto asked as Tsuna tried and failed at comforting Yae.

"I am talking about the ritual. The Crimson Sacrifice Ritual where one twin must strangle the other twin in the hellish abyss and turn them into a Crimson Butterfly. Poor Sae wants me to kill her! I can't do it though, I don't want to end up like Itsuki…"

"Did he dye his hair yet?" Tsuna joked. At this Yae burst into tears. "Did I say something wrong?" Tsuna asked with a tilt of his head and confused expression.

"Itsuki is dead. He hung himself after helping Sae and me to escape."

"Oh. I am really very sorry to hear that," said Tsuna and Giotto in perfect unison.

"Our father still wants to do the ritual as well, so we must hurry and get Sae out of there!" screamed Yae. "Follow me, we have to leave now!" she yelled as she started running out the door towards her home.
