Yamamoto walked into his room, well, more or less his and Gokudera's room. It had been a long day for the laid back and carefree Japanese man. He managed to take off his tie, suit, and shoes and put on a t-shirt before collapsing onto the bed, nothing on his mind but sleep. It had been several days, no, weeks, since he's had some decent sleep. He began to drift off as soon as he felt the comfort of the bed only to be awoken by Gokudera's yelling.

"Damn it! You two are too damn reckless!" yelled Gokudera from the kitchen. Two tall, scared figures disappeared through the door as Yamamoto made his way to the kitchen. He wandered in to find his precious Italian squatting down to pick up the shattered glass all littered across the kitchen floor. Kneeling down to help him, Yamamoto chuckled to himself.

"Those two never stop, do they?" Yamamoto asked, smiling as usual. Looking up from the ground, his gaze met with Gokudera's piercing glare.

"Of course they don't. They act just like you. Always so carefree and reckless," snapped the angry Italian. He never liked the way Yamamoto took everything like it was some sort of joke, but over the years, he's learned to deal with it. Two heads poked around the door and checked to see if the storm had died down.

"Umiko, Hiko, please apologize to your mother," Yamamoto said ever so calmly. It aggravated Gokudera so much right now because his two children had just broken an expensive tea set. The two young Vongola guardians-to-be made their way over to their parents.

"It was an accident! We swear!" Umiko spat out as quickly as she could. Her twin brother, Hiko, gave a small nod and turned his head to the side. "We're sorry, Mom. We really are. Right, Hiko?" Her brother gave no reply, and she shoved an elbow into his side. Hiko curled over in pain. "Uh... Y-yeah. Sorry, Mom!" He shot his sister a deadly glare.

"Tch. You two need to be more careful next time! You should be glad your father was here. Otherwise, you two wouldn't be off the hook so easily!" Gokudera warned. Even though he knew it was an accident, he couldn't help but be angry because the tea set was a gift from his sister Bianchi.

"Alright, now that that's settled, how about we-" Yamamoto stopped mid-sentence when he saw Umiko disappear into a cloud of pink smoke. Gokudera looked at Yamamoto, shock and fear painted on his face. Their daughter had just been sent into the future by the ten-year bazooka. "Oh no."

The smoke started to disperse and coughing could be heard. A tall shadow could be seen in the cloud. As the cloud finally cleared, a girl stood before them, covered in blood with a sword and gun in her hands. Fear was clearly visible on her face as she looked at both Yamamoto and Gokudera before she collapsed on the floor. Yamamoto immediately went to help her or at least try to tend to the wounds. Hiko stood there flabbergasted as he looked down at his sister from the future.

"Hayato, go get the first aid kit!" Yamamoto said as he ripped the sleeve of his shirt to tie the wound on Umiko's arm. Gokudera nodded and ran off to do as he was told. "Fuck…" muttered Yamamoto as he saw the blood gushing from various wounds. "Hiko put some pressure on her thigh." Hiko did as he was told and put both hands on his sister's thigh to stop some of the bleeding as his father ripped another piece of his shirt to tie around the leg wound. Gokudera had returned within moments with the kit and helped tend to his daughter's wounds.

"How the fuck did she end up like this?" Gokudera choked out, obvious that he was trying so hard not to cry.

"I don't know, but we'll find out when she wakes up," Yamamoto said as he picked her up and took her to her room. Even though his daughter lay in his arms injured, his mind was focused on something else. Something that made him feel sick to his stomach. Hiko followed them to Umiko's room, still trying to let his mind process everything that just happened.

The next day…

Umiko woke up, unaware of where she was. She attempted to sit up but failed as she felt the pain surge throughout her entire body. Shifting slightly, she looked around to try and figure out where she was. Feeling the movement, Yamamoto, who had fallen asleep at the foot of the bed, woke up. He saw that Umiko was awake and relief radiated off of him.

"D-Dad?" Umiko stammered. She was absolutely confused beyond imagination. All she remembered was she was in Italy helping out Undicesimo's friends, and now she was here. The door to the room opened with a loud thud. Gokudera rushed in and stood next to Yamamoto. He got the feeling that Umiko had woken up, and now he knew that his maternal instincts hadn't failed him. "M-Mom?"

Sighs of relief came from both Yamamoto and Gokudera. "Umiko, what the hell were you doing that got you wounded? You were hit by the ten-year bazooka, and then you show up covered in blood! What the hell!" Gokudera shouted, shaking with tears in his eyes. "Hayato…" Yamamoto wrapped an arm around him, pulling him into a hug. Gokudera buried his face in Yamamoto's chest.

Umiko was shocked by Gokudera's sudden outburst. Her mother had never done anything like that in the future. However, now that he mentioned her brother, she burst into tears. It never occurred to her that she was ten years in the past until her mother had mentioned it. Now that she knew, all of the things that happened in the future hit her hard. "Mom, Dad, I'm… I'm sorry… I'm so sorry…"

"Ma, ma, you two! Please don't cry!" begged a worried Yamamoto. "Umiko, what's wrong? And why are you apologizing?" He wiped away her tears with his free hand. Gokudera turned to face Umiko when he heard her cry. "H-Hey! Umiko, please don't cry. I… I didn't mean what I said. I really didn't!"

"N-No… It's not y-you, Mom… It's H-Hiko… A-And...every...everyone... else..." Umiko said between sobs. Hiko, who had been outside of the room, heard his name and leaned closer to the door. "I'm sorry I couldn't… that I couldn't stop e-everything t-that...h-happened. I promised that I would keep them s-safe. But I…" She was cut off by Yamamoto holding up his hand.

"Umiko, calm down, breathe, and explain." Yamamoto could tell this was going to be a long, difficult story. Hiko sat down next to the door. He hated eavesdropping, but he got the feeling that this was going to be something important. Not only that, but he had a feeling Umiko wasn't quite ready to see him so he remained outside as he waited for his sister to begin her story.
