Ryu- Hey readers, sorry for the delay. I was sorting out everything from the characters, time, to other. There will be three OC groups for the plot purposes, and it will be around three years after the future arc.

Also, I've changed things around so things have changed now. Pairings may be included if asked for. Examples are 10027, 1827, G27, 6927, etc.

Rise of the Blood Moon

It was a Sunday afternoon when Tsuna was interrupted from his studies by Reborn. This was a surprise to Reborn because Reborn never bothered him during his studies, only during most other times.

"Hey Tsuna, are you no longer surprised by the history of the Vongola?" Reborn said. "No, why do you ask?" Tsuna said.

"Well, are you aware that the rare, once in a couple centuries, red moon is going to rise tonight?" Reborn said. "Yeah, but what does that have to do with the history of the Vongola?" Tsuna said.

"It has everything to do with he Vongola. We call it the Blood Moon. You know why?" Reborn said. "No." Tsuna said. "We call it that because the Blood Moon unlocks the powers of Vampires, Werewolves, and Slayers." Reborn said.

Tsuna simply stared. Then he blinked, and then he finally spoke. "W-what!? You can't be serious." Tsuna said.

"Was it a surprise that you were the heir to the Vongola throne." Reborn said. This was what got Tsuna. "Fine, I'll half believe you for now, but if it's a trick, I'll make it hard for you to train me." Tsuna said.

Reborn just smirked. "Hmph, it's always hard to train no good- Tsuna." Reborn said, then he left. So Tsuna was left to his studies again, but this time, he was pondering Reborn's words.

Soon, hours had past and night was beginning to fall and Tsuna's hyper intuition was telling him that something was going to happen.

Then Reborn had suddenly appeared in front of him from out of no where. "HIIIII!" Tsuna cried in surprise.

It was then Tsuna noticed slight changes in Reborn, there were fangs sticking out of his mouth, his eyes seemed to have a red tinge, and Reborn's skin seemed to be very pale.

Tsuna also seemed to notice that Leon was no longer a chameleon, but a bat, who was now hanging from the edge of Reborn's hat.

"Tsuna, we're going to go out for a walk." Reborn said. "Okay." Tsuna said. So Tsuna got his shoes on and they both left.

While they walked, Tsuna noticed that the Blood Moon, as Reborn had called it, was high in the sky. Everything seemed normal, until a bat flew past Tsuna's head.

"HIIII!" Tsuna said as he fell. When Tsuna recovered, he stood back up only to notice that the bat had suddenly turned into a person.

"HIII! What happened to the bat." Tsuna said it was then Tsuna received a kick to the head by Reborn. "Now do you believe me?" Reborn said. "Fine, I believe you, but why isn't anyone panicking?" Tsuna said.

"It's because no one is aware. Those who have weak flames are controlled by the instincts of their blood." Reborn said. "So how come I haven't changed?" Tsuna asked. "I don't know, but we're going to meet your guardians, they should be at the school by now." Reborn said.

"You called everyone together, wait, what school?" Tsuna said. "Namimori High School of course." Reborn said. "What, why!" Tsuna said. "You're forgetting about Hibari. It was hard enough to get him to come, the school is good enough." Reborn said as he suddenly grew bat wings and flew away.

"Hey, wait for me!" Tsuna said as he ran after Reborn.

Soon, they had reached the gates of Namimori. It had been a while since he had been here, so it was nostalgic. Tsuna was suddenly thrown out of his memories when Reborn kicked him. "Don't daydream, let's just go in." Reborn said. "Reborn, it's night. So I wouldn't be daydreaming." Tsuna said.

"Yes, but to us creatures, it's day. So hurry up and get inside, we're losing daylight." Reborn said. Tsuna sighed and walked inside the building.

Since it was night, all the halls and rooms were dark, but Tsuna had been here at night before during the Ring Battles. So it was no surprise.

Soon, they had reached the door of the reception room, and already, Tsuna could hear shouting inside. Tsuna sighed, and then opened the door, what he saw surprised him very much.

Tsuna could see some furry creatures, that looked like dogs. Also, Tsuna swore that most of the others had glowing red eyes.

It was then Gokudera noticed Tsuna. "Tenth!" He said as he ran over to Tsuna. "Oh good, you're not affected." Gokudera said.

"What?" Tsuna said. "Tsuna, you're forgetting about what I said." Reborn said. It was then everyone turned their attention to Reborn.

"I guess I have to explain everything. So listen closely, tonight is the night that the Blood Moon rose. This moon is able to unlock your power hidden in your blood. So your form is either that of a werewolf, vampire, or slayer." Reborn said.

Everyone nodded at the new information, even though it sounded ridiculous.

"Tsuna, you might want to take in account which guardian is what creature." Reborn said, and Tsuna nodded.

So Tsuna looked over his guardians. He saw that Gokudera didn't seem too different, but the fangs that were sticking out when Gokudera was smiling immediately told Tsuna, vampire.

Hibari only had slight physical changes as well, but his blood lust seemed to be far greater than normal, so Tsuna guessed vampire.

Yamamoto and Ryohei were the "dogs" that Tsuna had seen earlier, so Tsuna guessed werewolf.

Lambo didn't seem any different at all, but Lambo's will to kill Reborn was even stronger now, so Tsuna had guessed slayer.

Finally, Chrome seemed to be normal, but Tsuna saw the glint of her fang slightly sticking out of her mouth, so he guessed vampire.

"Well, it seems you have at least one of each in your family." Reborn said. "But what about Tenth, he doesn't seemed to be affected at all, maybe he doesn't have any power." Gokudera said.

This both made Tsuna happy, and bad at the same time. The good part was that Tsuna might not be anything, but the way Gokudera had said it, well, seemed to have a different meaning.

"Don't worry, we're going to figure that out by calling our Familiars." Reborn said. "Familiars?" Tsuna said. (1)

"Yes, all creatures have Familiars. Now light your flame on your Vongola ring and let a single drop of your blood fall into the flame. We'll start one by one." Reborn said.

It was then Mukuro had suddenly appeared and decided to go first. He explained with the 'excuse' "Chrome doesn't like blood that much." So he pricked his finger on one of his fangs and let the blood drip into the flame. The flame flickered, and then it suddenly flew off his ring and then turned into a black reddish bat.

Yamamoto went next, because he thought that the 'trick' was cool. So he did the same thing, and a pitch black wolf appeared.

Lambo didn't want to do it because he said it would hurt, so he used his 10-year-bazooka and TYL Lambo appeared. He did what Lambo couldn't do and a black white striped dog appeared.

Gokudera went after saying that his Familiar would be better. A gray bat appeared, but what was weird was that it seemed to act like a cat. (2)

Hibari was next, but he said "Hibird will do just fine for me." So it was left at that.

Ryohei went after and when the blood made contact with the flame, it flickered violently and then a big gray wolf appeared.

Tsuna was last. Tsuna hesitated a little, but decided that doing it would get things done quicker. So when the drop of blood fell, he was surprised when the flame hovered off his ring and began to grow larger.

Then it formed into a figure that seemed familiar. Soon, it solidified. It was-

-To Be Continued-

1. I'm capitalizing it so that I won't confuse it with the other word.

2. I read some where that Gokudera has a thing with cats. So I thought it would be funny.

Ryu- Oo, I'm bad. Not telling you what Tsuna's Familiar will be. Though I did leave a hint, I hoped you noticed. Oh, and don't forget to say whether or not you want pairings.
