I am the first living being to create a fanfiction of these two shows. This is a crossover pairing too! So enjoy!
Crossover: Happy tree friends + Katekyo hitman reborn
Crossover pairing: Hidden pairing
Version: anime (obviously)
Tsuna opened his dark caramel eyes, which have not yet adjusted to the light. Once they focused he saw trees and noticed he was lying on a pile of leaves.
This wasn't right, obviously this wasn't right! He stood up and looked at his surroundings.
"Am I in Namimori forest!? Tsuna yelled.
How did he get here? It was obvious that reborn had to do with this. Tsuna found a note that read: Here Dame-Tsuna, I Have dropped you off at Namimori forest. There is a nearby town outside of it. Find your way there and two of your guardians will be there. Good Luck!
Reborn
"Of course." Tsuna said annoyed. Tsuna started walking and looking around. He has gone here before, but none of it was familiar. After about a half an hour Tsuna found a sign that read: town ahead, full of joy and happiness known as happy tree town population: 21, Cute by day dark by night
"Was this the town reborn was talking about?" Tsuna asked himself.
He then walked towards the direction the sign was pointing. About five minuets later Tsuna arrived at the town. Buildings were colorful and hardly any people were out.
Tsuna walked down the hill only to slip and roll down. "Ow." He said.
Tsuna stood up only to be confronted by a flying teen with blue hair wearing a tracksuit. "Where did you come from?" he asked.
Tsuna thought for a while. "The woods." Tsuna replied.
The boy chuckled. "Ok, my names splendid how about you?" he asked.
"Tsunayoshi Sawada, but you can call me Tsuna." He explained. "Ok, Tsuna let me show you around happy tree town. Oh and if you saw the sign, there are more than 21 people here." Splendid explained.
"That explains a lot." Tsuna told himself.
Splendid motioned for Tsuna to follow him. It was really a small town. It only took an hour to tour.
"Let's go meet some friends" splendid said happily. Tsuna smiled and nodded.
Splendid took flight. "Try and catch up with me!" he said before flying away at full speed. Tsuna chuckled. "Oh I will!" he yelled back.
He reached into his pocket and luckily he had his dying will pills and X-gloves. He put a pill into his mouth and swallowed. His chocolate eyes turned orange and his sky flame above his head.
Tsuna never used this for games and races but this guy had powers. Tsuna flew up and caught up to Splendid in less than a second. Splendid looked behind him and saw nobody and laughed.
He then looked to his lest and saw Tsuna smiling at him. "How did you and you look different!" splendid yelled. Tsuna just chuckled.
"Not to mention your voice is deeper." Splendid added. "We land here!" splendid yelled.
HDW Tsuna nodded and they landed. The brunette's landing was swift as he left HDW mode. Tsuna put his gloves into his pocket.
"You just quickly changed from adorable to awesome, that was friggen awesome!" splendid yelled.
"t-thank you." Tsuna turned a tint of red. Splendid blushed from the cuteness overload.
Tsuna looked at the house that looked like an army base. Splendid knocked on the door and it opened. It revealed a teen with green hair wearing a camo plus a matching hat.
"Oh hey splendid what's up?" he asked.
"Flippy I want you to meet someone. He is cool and has powers!" splendid yelled startling the veteran.
"Hey Tsuna come in and meet Flippy." Splendid said getting Tsuna's attention. "Geez everyone here has a weird name and not to mention splendid yells too much." Tsuna told himself.
"Hi my name is Flippy." He said smiling. "Oh you guys can come in if you like I don't mind and I have company over." Flippy said.
"N-no its fine." Tsuna said.
"I forgot to ask how old are you?" splendid asked.
"I'm 14." Tsuna replied.
"Oh I'm 16 and Flippy's older than me he is 17." Splendid said.
Splendid and Tsuna walked in with Flippy behind them. Tsuna saw 3 people one with a rabbit sweater and yellow hair, one with a purple sweater and purple hair with freckles across his face and one with a yellow and green sweater that had mismatched eyes.
"Who is that?" the one with the light green hair asked smiling. He was ignored instead.
"Tsuna this is toothy." Splendid pointed to the boy with freckles. "And that's cuddles the one with the yellow hair and that's nutty." Splendid said.
"16, 17, and 15 in that order." Flippy said.
'Hi splendid!" toothy yelled. "Oh hey toothy." Splendid said. "Guys this is Tsuna."
Cuddles got up and walked to Tsuna. "What's up Tsuna I am cuddles." He said putting an arm around Tsuna's shoulders. Nutty ran up to him and smiled. "I love your eyes, they remind me of caramel!" nutty said. Tsuna smiled.
Tsuna noticed that Nutty's eyes were mismatched one was a nice green and the other was dark yellow. He decided to brush it off. Tsuna felt a hand on his shoulder. "This place isn't so bad as long as you don't die and meet everyone." Toothy told Tsuna.
'Don't die?" Tsuna asked confused. "It's a long story, don't think about it much." He added. Tsuna nodded.
"Hey have you heard of those people going around asking where their boss is? Flippy asked splendid. "Hm? Oh yeah I have seen them the short one got up in my face yelling tenth in Japanese. Jyuudaime I think." Splendid replied.
Tsuna over heard this and walked towards the two. "Wait what did those two look like?" Tsuna asked.
"Hmm one had short silver hair and is short tempered and one had black hair that was cheerful. Both of them are taller than you." Splendid said.
Tsuna face palmed himself. "Let's go find them." Tsuna said annoyed. Splendid nodded. Tsuna went into HDW mode and they flew out.
"Crap Flippy!" cuddled yelled. Flippy stared at the fire until his vision went black. Cuddles covered his eyes. Flippy was breathing heavily showing that he was changing.
Toothy also ran up to him. "Calm down flips don't let it get to you." He said.
Flippy's eyes turned back from yellow to lime green. "We have to tell Tsuna about this or he will never know." Toothy told cuddles. Cuddles nodded.
Splendid and Tsuna were flying over town and there was no sign of them. "Hey Tsuna do you know who those two are!?" splendid asked.
Tsuna nodded.
"They are my friends, or as my tutor say my guardians." "Oh." He replied.
Tsuna then spotted Gokudera and Yamamoto. He then flew down at full
Speed.
"Tsuna wait that's too fast!" splendid yelled.
Tsuna didn't hear and quickly went out of HDW mode. He ran into Gokudera and dragged him down and against the floor.
"What the hell that hurt why the hell did you do tha-Jyuudaime!" Gokudera yelled happily. "Hi Gokudera-kun!" Tsuna said smiling. He got up and helped Gokudera.
"Yo Tsuna!" Yamamoto said. "Hi yamamoto." Tsuna said.
Splendid landed and saw Tsuna with his friends. Though he felt odd. Seeing Tsuna with his friends made him feel weird. It's like he doesn't want Tsuna with them. But why?
"Hey Tsuna I am going to talk to a friend, you guys meet me at my house, here is the map." Splendid said giving them the map and flying away.
