Tsuna meets Sasagawa Ryohei while running for school. He drags the other with him by mistake and he is dumbfounded by the fact that the other didn't smack his head as soon as they stopped. Instead Ryohei is thrilled, he sees Tsuna as a chosen person.
The chosen person for the boxing club. He asks -no, he demands Tsuna to join the club and he doesn't want to accept the other's refusal. Tsuna says no repeatedly but in vain. It's a miracle that Kyoko appears before things turn out worse.
But as helpful as Kyoko is, doesn't manage to make her brother give up on Tsuna. Because her brother is the type of person who doesn't give up. Not so easily. Not without a fight.
On the other hand, Tsuna feels frustrated. He considers Kyoko to be his friend. Well, maybe they don't hang out a lot, but since the incident with Mochida, things have turned out pretty well between them. And that is a problem. A huge problem , because how can he get rid of Ryohei without using his power? He narrows his eyebrows in deep concentration. He needs to find another solution. There is a voice inside his head that tells him that killing people is not a solution, but he pays no mind to it.
''How do you make someone accept your refusal?'' He doesn't believe that he is really asking Reborn about this. Seriously, the guy can't even accept Tsuna's refusal to be a mafia boss.
Reborn looks at him with a blank expression.
''It seems that my student is having a problem. Is your problem Sasagawa Ryohei?''
''How do you know?'' He wants to ask but instead nods his head. Can he hope that Reborn will help him?
''Why don't you settle your argument with a boxing match? I have told Ryohei about this and he found the idea great. He will be here in a minute.''
''You want me to solve my problems with violence?!''
''Sasagawa Ryohei is an extreme person. You won't be able to solve this in any other way.''
''Do not tempt me, Reborn.''
''Master Pao Pao, I am here! Sawada! Join the boxing club!'' Ryohei shouts as he enters Tsuna's room.
''No! And who is master Pao Pao?''
''It's me.'' Reborn states and Tsuna screams mentally.
''Alright! Let's settle this to the extreme! Let's have a boxing match!''
''No, thank you.''
''Breath Tsuna, breath. You have the control of your power, not the other way around. You can't make a mistake. It will break you.''
''Sawada! You are a guy who can be found only once in a hundred years. I cannot let your talent get extremely wasted.''
''Why don't you accept my refusal? What will I have to do in order to be heard? If only you weren't Kyoko's brother. I want you to go away, to leave me alone, to stop bothering me. I want you to...'' He bites his tongue hard to draw blood.
He will not curse Sasagawa Ryohei. He can control himself.
But he will be a liar if he says that he doesn't want to. Ah the thrilling moment when he is cursing,how he misses that. The adrenaline that he feels, the satisfaction. The agony, the pain, the nightmares. He misses all of them.
''What am I? A masochist?''
There is a bitter taste in his mouth and he isn't sure if it's from his blood or from his thoughts.
''You have to make him accept your refusal with your dying will.''
Reborn states calmly and shoots Tsuna.
It's the second time that things don't go as the sun arcobaleno had planned.
Yes, Tsuna gets up and for a moment he seems like he is ready to encounter Ryohei in a boxing match.
It happens in a second and Ryohei is lucky that Reborn has extremely good reflexes, otherwise Tsuna would have choke him.
Reborn stares as his student, feeling the murderous aura from him. He understands now, Tsuna's previous question. He grits his teeth. That's a second mistake.
''You are an enigma dame-Tsuna.''
The next day at school, Tsuna is surprised to hear Kyoko apologising. She says that her brother can be a little persistent about things but he's not a mean person. She promises that Ryohei will apologise later too. True to her words Ryohei appears after school.
''My sister says that I need to start listening to people.'' He starts talking, not looking extreme at all. ''I guess I'll have to listen to her. I'm extremely sorry Sawada!''
''It's fine.'' Tsuna says. ''I guess that I'm extremely sorry too.'' He continues looking at the marks at Ryohei's neck.
Silence fall between them.
''I have to go. It was nice talking to you. Let's meet tomorrow too. I still hope that one day you'll join the boxing club. You are really an extreme guy!'' Sasagawa waves his hand and leaves.
''He runs around the town every day. You should join him.'' Reborn appears in front of him.
''No thanks!''
''Let me rephrase my words. You'll definitely join him.''
''Absolutely not!'' Tsuna shouts and runs into his house. Reborn sighs and follows him.
''We need to discuss.'' The sun arcobaleno mentions, closing the door behind him. They go to Tsuna's room.
''It's about me almost killing Sasagawa-san right? I don't want to talk about it.''
''Answer me only one question.'' Reborn has to ask what's on his mind. He's been thinking about it since the moment he saw how Tsuna reacted on Sasagawa's persistence.
''Fine. But only one.'' Tsuna gives the green light and the hitman doesn't wait any longer.
''Considering the fact that I'm also persistent on you becoming a mafia boss, did you ever think and maybe even try to kill me too?''
Tsuna's eyes widen. ''What are you talking about? What happened with Sasagawa-san was accidental!''
''Tsuna'', the way the hitman is speaking is calm but it sents a chill down the boy's spine. ''Has anyone ever told you that you are a terrible liar?''
Tsuna tries to escape but fails miserably. Reborn holds him down and he curses his fate. He screams and tries to shove his tutor off of him. Eventually, he gives up and just lies there staring at Reborn.
''You can't blame me.'' He speaks in a silent voice. ''Yes, I thought of killing you. So what? I don't want to hear any lecturing from a professional hitman. And to think that I trusted you and asked for your advice.''
The hitman gets off of Tsuna because the boy doesn't resist anymore.
''You are a horrible tutor, Reborn.'' Tsuna speaks again and the sun arcobaleno feels that a wall is being built between them. A wall Tsuna builts with his own hands and has no intention of breaking it down.
