400 years into the past...Vongola HQ.

A lady bearing long wavy black hair continued to hum her newborn child within her arms to sleep, her brown eyes softened as she smiled lovingly towards the child, "My dear son, Michael."

"WAH!" A violent thump was heard behind the bushes of the grounds, the lady gripped the fan in her hand as she proceeded to see who was close by.

Holding Michael close to her, she quickly moved from her chair in the shades to the direction of the sound.

Peering to the bushes she found three unconcious teens wearing unfamiliar clothing lying on top.

"Who are these children?" The lady wondered until one of the male servants of Vongola HQ arrived, "Lady Serena! Are you okay?! I heard a sound from the distance!"

"I'm fine, Roland,...but can you help me get these three children inside my quarters. Make sure, Giotto and the others don't see them," Serena answered to the worried servant, "I need to make sure Michael goes to sleep."

"I'll make sure of it, Lady Serena." Roland bowed as he proceeded to get help from the other servants.

400 years into the present...Vongola HQ

"AHHHHHH! REBORN-SAN, WHAT DID YOU DO?!" Shoichi screeched while gripping his red hair.

"I passed the apple," Reborn nonchalantly responded holding a smirk on his face.

"THIS IS BAD! THIS IS BAD! THIS IS BAD!" Shoichi cried until Spanner slapped him in the face.

"Get a hold of yourself, Shoichi..."

"Thank you, Spanner..." Shoichi mumbled, "But this is really bad! We don't have any way of returning those three back to the present!"

Michael stepped in this time, "For now, you guys try to find a way to return them to the present. Dino will handle covering for their absences at home and preventing the guardians for looking for them. Reborn, you shouldn't have done that."

Reborn tipped his fedora, "This may be a good timing for those three to learn something from the past, also...why didn't you go?"

Michael clenched his fist as he muttered to himself, "I don't want to bear the pain of seeing those two again."

Reborn watched as Michael stepped out of the room to let off some steam, "But this may be one of the few chances you get to see them."

Past...

Mayuri opened her eyes slowly to find herself in a bed, but the furniture around her was more of an older style rather than the current styles of furniture.

She was beginning to panick, "W-Where am I?"

"Oh you're awake..." Mayuri's eyes buldged as she watched, Serena or rather Nadeshiko, walk into the room, "Thank goodness, you're alright. I found you fainted in the bushes along with two boys around your age. Are they your friends?"

It was weird, since Serena was speaking in Japanese to her.

"Yes, they're my friends," Mayuri responded, "Can I see them?"

"They're still resting, but if you insist on seeing them..." Serena ushered in two maids into the room, "You need to wear this."

It was a dark blue kimono covered in rose accented decorations. Did Serena knew I was Japanese?

Mayuri wondered as she nodded understanding what Serena meant. The maids helped Mayuri change into the kimono immediately, by the time they finished, and left Serena whispered to Mayuri's ear.

"You came from a different time didn't you?" Surprising Mayuri out of nowhere, "That ring your wearing is the same as mine. Where did you get that?"

"I-I..." Mayuri was beginning to fidget, until one of the servants entered the room.

"Lady Serena, the other two are awake now."

"Thank you, Roland." Serena spoke in Italian, before returning to her native tongue, "I expect an explanation once you return to your friends."

Oh no...she saw my ring. I don't have my weapons either. How are we going to get out of this time period?!

Mayuri was internally frantic as she followed Serena down the hallway.

By the time Mayuri reached Tsuna and Enma. She was surprised upon how they also changed outfits to a much more older styled suits.

"Mayu-san!" The HDWM duo spoke in surprise.

"You're okay?!" Tsuna had a concerned face on him as Mayuri waved off while whispering, "I'm fine Tsuna. The only problem is...Serena."

All three turned their gazes over to the lady talking to the servant in italian for doing a good job.

"She knows about the fact we're from a different time period along with the rings..." Mayuri spoke quickly as Tsuna's face went from being concerned to horrified.

When the servant left, Serena gave what looked like a warm smile until she asked, "So why do you have three have the rings of the Vongola and Shimon founders as well as my ring?"

"We're in a lot of trouble..." Tsuna mumbled.

Present

"Okay I think we're able to send back a rescue team into the past to prevent any more damage," Shoichi reported to Michael, "However, while I was trying to find the three on the monitor...it seems they encountered a presence."

"What presence?" Michael peered over to the screen. The colors showed the flame signals of the trio.

Orange for Tsuna.

Dark red for Enma.

White for Mayuri.

Except there was another person bearing a white flame signal in front of the trio.

This can only mean one thing.

Mayuri, Enma, and Tsuna...encountered one of original guardians.

Serena, the illusory Star Guardian of the Vongola of the first generation, was confronting her own descendant as well as her boss' and friend's.

Michael deadpanned, "We're screwed."

"They're screwed, Michael. Not us." Reborn reminded.

"Hopefully the star guardian didn't find out about the rings..."Shoichi hoped.

Reborn shook his head, "Nope. If it's Dame-Tsuna and Dame-Enma...there's no way the people of the past can't notice the rings."

"Tsk..." Michael looked over to Reborn, who beared an all-knowing face, "We're going in."

"About time, Michael. Just about time," Reborn chuckled as he hopped onto his shoulder.
