Disappearance and Reappearance

Bang! Bang! Bang!

The sound of gunshots filled the air as the enemy famiglia kept on firing everywhere. Today was the Vongola Decimo's birthday, and a party which only had the Vongola and close friends invited since, the Decimo didn't want to hold a big part today. Everything had been going along smoothly however, right near the end of the party gunshots had started being heard and the enemy famiglia had started to attack. Everyone had scattered, of course after defeating those that had crashed the party directly. The attack wasn't a small scale one, and every corner of the Vongola mansion was being attacked.

"Fuck! Fuck! God damn it!" A young brown haired woman, of barely twenty yelled as she dodged bullets left and right, barely dodging some. "Of all times to show up! Damn it Tsuna! Where the hell are you!" Taking out one of her boxes, that Tsuna had given her as a gift when she had finally officially joined the Vongola, she summoned her lightning flames into her ring, and the box opened. It revealed two silver semi-automatic handguns. She then started to fire back as she simultaneously continuing to dodge. As she dodged and fired back she pushed onwards, never dropping her guard as enemies continued to fire.

"VOOOI! A loud voice yelled as a long silver haired man appeared slicing enemies with his hand sword. "What the hell do you think you're doing here Yume!?" The man yelled angrily as he continued to slice the rest of the enemies in the area that were left.

"What the fuck do you think I'm doing?! I'm killing these god damn fuckers as best as I can Squalo!" The now named young woman yelled at the silver haired man. "Ah, Crud!" She growled as more enemies appeared

"Well you're doing a piss poor job of it trash!"

Glaring she gritted her teeth as she down five of the oncoming enemies. and ran ahead. Not one to be left behind Squalo followed cutting down enemies as they approached. "I'm trying you crazy shark! It's not exactly easy when you're not the most skilled or experienced in a fight!" She yelled angrily as she took down another five leaving only scorched corpses. Her box weapons were special, they were modeled after the idea of Xanxus' own guns but instead of using bullets and flames hers allowed her to use her own flames in concentrated amounts. This benefited her as she didn't have to reload all the time, the only downside was that it drained on her flames and if she shot more than she could handle she knocked out for at least a week.

"Excuses! At your age trash, I already had more than a thousand kills and was a skilled assassin! He yelled as he finished off the last of the oncoming enemies.

"Tch. Well excuse me if we all can't be talented like you." She muttered the last part under her breath as she started moving on ahead again "Oi. Squalo have you seen Tsuna?" She asked as the man was muttering loudly as they moved on ahead.

"Che! That piece of scum was near the entrance of the mansion last I saw him."

Nodding, she headed that way, and faintly noted that Squalo wasn't following her. Not that it was surprising, he wouldn't go and help directly.

"VOOI! Scum tell that piece of trash we aren't helping because we want to! Only boss gets to kill Tsuna no one else got it!" He yelled from the back and turning her head she yelled back. "As if Xanxus will ever be boss!" Smiling slightly, she she then yelled. "But I'll pass on the message and thank you!"

As she neared the entrance, the sound of a battle increased once again and she tensed. Her training with Reborn and Lal Mirch had made her learn to instinctively become cautious whenever there was the sound of a fight. She shivered slightly at the thought of there trainings. 'Sadistic, spartan tutors.' She thought as she picked up her pace.

Once she neared the area of where Tsuna should be she saw Tsuna in Hyper Dying Will Mode finish off the enemy famiglia boss.

She frowned a bit knowing Tsuna didn't like doing this but it was unavoidable, he was head of the family after all. She snorted slightly, he didn't like that everyone had to do this and neither did she, but she made this decision. In order to protect her family and friends she would do what she had to. The same reason Tsuna finally stopped protesting about being boss.

Smiling slightly she saw that Gokudera, and Yamamoto who had been fighting off the other family members that would have interfered in the fight, ran towards Tsuna. She couldn't hear what they were saying but it must have been something serious. She then started moving towards them and halfways there she noticed movement out of the corner of her eyes.

A man. part of the enemy famiglia. had something small in his hands and seemed to be saying. "Damn you Vongola Decimo! But you will pay, boss thought this might happen so he had this made and gave me orders. Hahahah this shall be a bleak victory once you're gone!" He then through the object and without a second thought she sprinted towards Tsuna.

"Tsuna! Get out of the way!" She yelled as she shoved Tsuna aside and the object hit the back of her shoulder before a blinding bright light consumed her.

Tsuna's eyes widened in shock and horror! "Yume!" Gokudera had been quick in his actions and before the man could escape knocked him out unconscious. "Jyuudaime, don't worry we'll get him to talk once we get the chance!" He exclaimed, hoping that would lessen Tsuna's worry, horror, and fear.

"Yume….no Yume!" Tsuna choked out as he realized his friend that was like a sister to him was gone. Right before his eyes, protecting him. He had a painful feeling in his gut.

Upon waking Yume felt as if she taken a whole three weeks worth of Lal's training sessions in one day. 'Ugh! Everything hurts! Why?!' She whined mentally as she scanned her surroundings despite the pain and realized the unfamiliar room. It was somewhat rundown, with stains on the faded, yellow walls. These weren't the infirmary rooms used to heal the family members after a fight. Try explaining to the hospital and authorities for all those hospital visits if ever questioned. Yeah, it would not go well.

The appearance of her surroundings startled her and snapped her out of her mental whining. 'I can manage to whine and think about how everything hurts later. First off, I need to figure out where I am!" She thought as she looked around the room. ignoring the pain. and noticed that everything bigger than they should have. As she began to ponder on that fact she noticed her body felt weird and looked down and gasped as she finally realized why everything seemed bigger. 'What the!? My hands! My body! It's shrunk! What's going on here!?" She started to panic but forced herself to calm down. Reborn's words going through her mind.

Remember Bakayume, no matter what situation you're in you have to learn to stay calm and analyze everything.

'Right. Right. Stay calm. Don't freak out. Don't panic.' As she was lost in her thoughts trying to calm down she failed to notice that the closed door had opened and a woman had stepped in.

Clearing her throat the woman stepped towards Yume. At the noise Yume startled and was brought out of her thoughts as she looked at the woman in surprise. ' O Dio Mio! She's huge and so big!' Yume thought as she started straight up at the woman in front of her.

M:Hey Auzrebubble here. I hope you guys enjoyed the beginning of this fanfic. It's my first time writing this type of fan fiction officially and not just jotting it down on paper and never finish writing it because writing is too troublesome. I've had this idea of this type of fan fiction but never saw one on here for this crossover so I hope I didn't do a poor job at it. So I hope it was good and interesting. ^-^
