A/N: I decided to recycle some OCs from Ghost of a Chance into this one. If you're not familiar with it, Shizuka is Tsuna's twin sister. So the mafia families are dark guilds in this universe, including Vongola. Getting ready to visit my step family so I decided to upload this before I leave. Enjoy!

Dying Will Wizards

"Reborn is going to kill us." Tsuna whimpered, Shizuka rolled her eyes. "You're the one that didn't want to join a dark guild. It's about time we did something that wasn't decided by grandfather." She huffed. Both siblings were raised as civilians and wanted nothing to do with the criminal world, so they decided to flee before they were branded with a Vongola tattoo.

Tsunayoshi was a Sky dying will wizard. It was a magic unique to those with Celestial ancestors, most dying will users stuck to dark guilds. His sister, Shizuka, was a Sky-Mist dying will wizard specializing in flame gates. He was proud, and terrified, that she got a contract with a Hibari. Tsuna wasn't without his own help, one Christmas he had gotten a ring that held a guardian spirit. Natsu, a cute Sky lion, has been a constant companion ever since.

"What guild would be crazy enough to take in two dying will users?" Shizuka wondered after they got kicked out of the sixth guild that day. Natsu had gotten a bit too excited and the lion familiar ended up setting a chair on fire, one that the interviewer himself was sitting in. In the lion's defense the man was full of himself and only wanted to accept Shizuka. The Pegasus Guild was too weird even for their tastes.

Something blue had caught the lion cub's eye and he scrambled out of Tsuna's arms. "Good grief, not again." Shizuka groaned. "Natsu!"

Happy was walking with Lucy and Natsu when he was barreled into by a mix of flames and fur. "Gao~" The cub mewled, playfully pawed at Happy's wings. "Get offa me! It's going to eat me!" Happy cried. Lucy chuckled. "I think it just wants to play." "Wonder where it came from." Natsu comments. "Natsu! Come on little guy, where are you?!" Happy and Lucy both snickered, the lion cub looked up. "Gao~" "I am not little, stop laughing!" The pink haired wizard yelled, Lucy and Happy just laughed harder.

Two teens ran over and the lion jumped into the arms of the boy. His female counterpart gave the lion a stern look. "Natsu, how many times have we told you not to run off? I told you he needed to go back in the ring." She says, the lion cub whined. "That little cutie is your familiar?" Lucy asks, her eyes glinting. "Yeah, Natsu is a Sky lion." Shizuka noticed the greedy look in the blonde's eyes and shot her a look. "Natsu is family, he's not for sale."

"Did you really have to name it Natsu?" Natsu grumbled, both siblings shared a confused look. "Why would that matter?" "I'm Natsu." He states, pointing at himself. "Huh, weird. Well I'm Tsuna and this is my sister Shizuka. We're both dying will wizards." Tsuna says, holding out his hand in greeting. Shizuka just waved nonchalantly. "I'm Lucy and this is Happy and Natsu. We're members of the Fairy Tail Guild!" Lucy says proudly. "Fairy Tail?!" "One of the strongest and most destructive guilds in the country?" The twin took both the wizards hands in unison, tears running down their faces. "Please take us with you!"

The Fairy Tail Guild was very similar to Vongola, especially with all the eccentric wizards that they drew in. There was a well endowed woman drinking beer out of a barrel and a man with such a wide build he could have easily passed as an easel. One thing that Shizuka didn't want to deal with was the teen that was currently stripping down to his underwear. A heavy blush covered her face as she hid her face with a scarf she had just created. Lucy glared at Gray, fire burning in the background behind her.

"Gray, put your pants back on! There are ladies present!" Lucy yells, punching the ice wizard in the head. As the blonde continued to chew out Gray, Shizuka found herself being pulled toward the bar. "Don't mind them doll, out of all the crazy things to happen here that is very tame." Loke comments. Shizuka deadpanned. "That's alright, Tsuna's tutor had him stripping all the time." She says with a shrug. "Shizuka! I thought we agreed not to discuss that!" Tsuna exclaimed.

Shizuka grinned mischievously. "What? Part of being a sister is embarrassing my adorable brother." There was a crash in the background, now Gray and Natsu were both brawling. Shizuka and Tsuna were both having flashbacks of Mukuro and Kyoya beating each other to a pulp. "Is anyone going to stop them?" Loke shrugged. "Normally Ezra would, but she's on an S rank mission. It'll die down eventually." Shizuka and Tsuna shared a look. That meant whoever had to foot the bill would be forced to intervene.

"I handle the shirtless one, you deal with Natsu?" Shizuka offered, noticing movement from the banister. Tsuna nodded as they both approached their targets. Tsuna absorbed Natsu's flames while Shizuka used Mist flames to coax Gray into falling asleep. A single finger with indigo flames touching his forehead and he was out for the count. Tsuna turned his attention to Natsu. "Couldn't you guys at least take your fight somewhere not filled with bystanders?" He asks calmly, Vongola's signature flame blazing on his forehead.

The Sawada siblings both heard slow clapping come from above gave both wizards a grin. "Good job, both of you. I take it you two are the ones that set Ichiya on fire." Shizuka let out a frustrated groan. "It wasn't our fault! He kept making my sister uncomfortable and Natsu didn't like it, he's usually well behaved!" Tsuna exclaimed. Everyone stared at Natsu, the wizard. "Not me, the cat!"

"I see, the two of you wanted to avoid being recruited into a dark guild. And you're looking for a guild to take you in." Mavis nodded to himself. Tsuna and Shizuka both fidgeted, distracted by the large stack of damage reports on the guild master's desk. "If you could rein in some of our more destructive members, you're more than welcome to join."

"Alright! And that Hibari bastard said we wouldn't find anyone crazy enough to put up with us!" Shizuka cheered, Tsuna deadpanned. "Please don't poke a bear with a stick sis." Shizuka gave him an innocent smile. "I'm not going to poke him with a stick, I'm hitting him in the head with a shinai."
