Chapter 1: An Extreme Meeting

"EXTREEEEME PACKING UP‼!" Ryohei screamed as he started packing all of his important belongings in his small bag since according to him, a man should have as little as belongings as possible. As he was busy with his packing, his phone suddenly rang startling Ryohei a little bit. He looked at the caller ID and noticed that Shoichi was calling him. He then immediately answered the phone thinking that something important has happened.

"Hello to the EXTREME Shoichi!" Ryohei shouted making the person at the other side at the phone cringed at the loudness of the voice.

"Hello to you too, Sasagawa-san." Shoichi replied in his very timid and shy voice of his.

"What can I EXTREEMELY do to you Shoichi? Do you need some help?" Ryohei asked still in his loud voice.

"Well, it's just that I received some call that the Vongola branch in Gotham city is under attack by a villain name Joker." Shoichi said in a very worried tone since people inside the branch might get hurt.

"WHAT! I EXTREMELY DON'T UNDERSTAND! How could some clown-man EXTREMELY cause chaos on that branch? I thought that branch is one of those branches that are EXTREMELY tough since it has survived one the fights between Mukuro and Hibari? If they survived, then I'm sure that they could survive all the tricks of clown man." Ryohei said making Shoichi sighed in relief that Ryohei wasn't as extreme as he was when he was still a teen. Though the sun guardian still lacks understanding and needed more common sense as any of the guardians are. He is still an idiot after all.

"Well, that clown man is very dangerous, Sasagawa-san. He is a villain known in Gotham city and he might do something to the people there. Clown man might make the people there angry and we know what will happen if there might be another fight after what you had done?" Shoichi said making the sun guardian widened his eyes and shiver a bit at the thought when Tsuna saw another destroyed facility. No doubt he'll become angrier than before.

"What should I EXTREMELY do Shoichi? We had to stopped clown man before the people there declared war on him especially since that person hadn't fully recovered from the mental torturing Mukuro accidentally placed on him." Ryohei said in a concerned voice as he remembered some poor unfortunate victim which happened to be the boss in that branch. He got accidentally caught in one of the illusions that Mukuro made and was placed in at the mental asylum for 5 whole months. He just recently recovered and had the tendency to be insane and become a crazy maniac whenever he had a tantrum. All in all, he acts just like Xanxus though not as extreme as him.

"Well, we had to stop clown man before he does something he might regrets. He might be super villain. But, Alfero-san is very scary than any super villain if he gets very angry." Shoichi said referring to the boss of the Gotham Vongola branch. "You had to hurry up. A pilot is now waiting for you at the rooftop-Oh wait! I forgot that there is now no rooftop since you had destroyed it. Good thing that I placed my base underneath the mansion so deep that you won't destroy it as well." Shoichi said as he mentally whooped for joy. "Now let see," Shoichi added as he looked from his computer on the other side. "Oh! Here it is. He's waiting for you just outside the forest." Shoichi said as he gave a cheerful smile to Ryohei. "I had already packed your suitcase which contains the detailed information of your mission. Good luck, Sasagawa-san!" and with that, the line went dead as Shoichi disconnected the line.

"I really didn't understand the mission very much but it might be EXTREME!" Ryohei shouted as he quickens his packing more in order for him to get started on his mission already. He was really excited in meeting more strong people in the future. The fact that these people he was going to meet was Supers. When he was done with his packing, he ran hurriedly to the outside almost bumping Gokudera with his enthusiasm.

"Hey watch it you Turf-top!" Gokudera shouted as he proceeded his way to Giannini's room.

"Didn't see you there TO THE EXTREME, Octopus Head!" Ryohei shouted as he continued to run outside. When he had finally made it out outside, he then looked at the mansion for a while as if he was memorizing every detail of it but knowing him, he would definitely forgotten it. But at least he tried, after all, he wouldn't be seeing the mansion for a long time. Never mind the fact the he would be only gone for three whole months. Once he was done looking at the mansion, he then went to the plane that was waiting outside the forest just as Shoichi had said to him. The plane started and was now on the air. Ryohei, who only there kept his grin all the while thinking of the many strong people he would definitely meet.

'I have to recruit them to my unofficial boxing club! They would be an EXTREMELY good addition to it!
