Chapter 2: Enter Adult Harry & Adult Takeshi!

Harry was having a calm conversation with Takeshi when suddenly a shadow appeared. "Lambo-san will kill you this time, Reborn!" Lambo exclaimed as he started tossing grenades at the baby hit-man, who simply knocked back towards Lambo.

They exploded in Lambo's face, make tears form in his eyes. "Hold. It. In." He whimpered, before failing to and pulled out the Ten Year Bazooka, and was about to use it on himself only for him to trip and it landed on Harry Takeshi, who were sitting next to each other talking.

POOF

A shirtless Takeshi & Harry appeared in Tsuna's bedroom. "AHHHHH!" The two men screamed as they stared at their friends younger selves. "Yamamoto, Harri?" Tsuna asked stunned as Reborn smirked at them, causing Harry to scowl at the baby.

"Hiya, Prim- I mean Tsu-kun."(1) Harry said excitedly as he pulled Tsuna in for a hug. "Lambo-san want's to know why you are shirtless?" Lambo asked innocently causing both of the 24 year-olds to blush slightly. "I know what they were doing, they were going to have sex." Bianchi said as she stepped into the room.

Gokudera collapsed after staring at her. "Lambo-san wants to know what sex is! Is it a type of candy cause if it is then Lambo-san wants some!" Lambo exclaimed happily, causing everybody but Reborn & Gokudera (But he's out cold right now so he doesn't count) to sweatdrop. "No it's not a type of candy, and we'll tell you when you're older, here eat this." Harry said as he handed Lambo a piece of grape candy.

"You carry grape candy on your person, Potter-kun?" Bianchi asked the man sounding amused. "Yeah." Was all Adult Takeshi said before pouting as Harry pulled on a shirt, he pulled out of thin air. "Ano, You two are married in ten years?" Tsuna asked awed at his friends strong relationship, while ignoring Bianchi's attempts to get him to eat her poisoned cooking.

"Yep, going on four years now." Harry said proudly, as Takeshi pulled his own shirt on. Harry pulled something out of his pocket and handed it to Tsuna. "Give this to my younger self, don't look at it." Tsuna nodded his head saying he understood.

Takeshi placed his finger on Tsuna's forehead and whispered; "Unlock!" (2)"Say Hi to Dino-kun for us." Harry exclaimed as they vanished.

POOF

The younger Harry & Takeshi blinked disoriented at the switch a little. "Here, Harri-kun. You're older self told me to give it to you." Tsuna said as he handed the package to Harry. "Thanks, Decimo-sama." Harry said blandly.

"Well what is it?" Gokudera asked annoyed after Bianchi left. "It's none of you're business Gokudera-san, we'll be leaving now Decimo-sama!" Harry said frowning as he & Takeshi stood up and started to leave the room. "We are leaving won't be back for a week.." Harry said shortly to his friends.

A week Later

Harry stared at his new bracelet. 'This thing is my new ring.' He thought to himself as he glanced at Takeshi who was now wearing a necklace. "Hahaha! I wonder how Tsuna-sama will react to us getting our Vongola Rings upgraded using penalty (3) from your future self, Harri-kun?" Takeshi said as he fingered his new box animal that was in with the stuff that Future Harry & Future Takeshi (4) placed in hiding for them.

"He'll be understanding we couldn't give them their rings from the future for obvious reasons. We are the only ones with the full Vongola Rings. Varia will confront us soon, you know." Harry said calmly. "Yes I do, and we only have Wind & Rain." Takeshi said referring to his necklace & Harry's bracelet.

"We need to get going, Tsuna might need our help." Harry pointed out to his boyfriend, who nodded his head in agreement. "Hahaha, crazy things tend to happen around him!" Takeshi agreed with his boyfriend.

"Ciaossu, Harri, Yamamoto." Reborn said smiling sightly. (5) "Yo, Reborn, Tsuna." Takeshi said as he sat at the table in Tsuna's kitchen. Harry smiled slightly as he ate breakfast with his new friends. "Ano, where did you two go?" Tsuna asked curiously causing the room to become silent.

"We went to retrieve some things of ours." Harry said calmly as he stared at Tsuna amused at the annoyance in the Decimo's eyes. "We now hold the Rain & Wind Vongola Gear, which is upgraded versions of the Wind & Rain Vongola Rings. Bracelet of the Wind Version X can only be used by me, while the Necklace of the Rain Version X can only be used by Takeshi." Harry said softly as Takeshi was rambling about baseball.

Ten Years Later

A twenty four year old Harry sighed as he relaxed in his husbands arms. A six year old boy with black hair was scolding a two year old boy with blonde hair about running with sharp objects. "Hahaha! Seth (6) is just like you, Harri." Takeshi said to the leader of the CEDEF and Tsuna's External Adviser, causing the slightly younger man to pout.

Dino smirked from where he was sitting down reading a book. "Be-careful what you say, Take-kun, he can poison our food." Dino said jokingly to his younger husband. "Yeah, well Ryu (7) is just like you, Keshi-koi." Harry said annoyed at his husband teasing him, this caused the swordsman to start laughing. "I don't deny that, love." Takeshi said happily as he eyed his family.

Harry rolled his eyes at both of his husbands antics. He now wore a silver trench coat with a hood that was pulled down. On his right hand he wore his Mist, Wind, Rain, Cloud, & Storm rings, which had chains wrapped around them, and his left hand he wore his wedding ring. Takeshi hadn't changed much over the course of ten years, but he now had a scar on the left side of his chin. He was still the same cheerful person he was when he was younger only now he also was married and had three sons.

Basil smiled at his three lovers, & three children. "Jianliangis (8) is a green eyed version of Basil." Both Takeshi & Dino said in unison, making Harry laugh at their antics. "Don't laugh at us, he started it! No You Did! No You Did!" The two men mock argued!
