Oh he was pissed. Fuming. But of course he couldn't say anything unless he wanted a slap on the back of his head dealt out by that coach. Sure this kid was pretty much impervious to pain, but the fact that someone could push him around was dealing out damages to his pride. He couldn't very well go around fighting people here because a simple kick dealt from him was liable to snap a person from this world's back- it seemed as though their bones were weaker here or something. Not to mention he'd been deemed 'crazier than the coach' after having given his assistance with the training menu. Apparently his 'stats' from what Riko had said were off the charts and after seeing a few examples of his strength, she'd asked him to help with training her team, though with his non-life-threatening exercises. He had suggested running with 20kg shoes, which was how he had started out, she looked a bit dubious because she knew he was being dead serious, they had laughed and called him a cute little kid with a good imagination when he said he'd started using those when he was even younger than he was now. He'd just about thrown one of his yo-yos at them- 50kgs in itself. After the exercises he suggested handing out increased in levels from 'unreal', 'impossible', to 'this kid's insane' when they realized he was as serious as a heart attack, Riko had pretty much given up, and he was sent off to go take a walk around town at the promise of avoiding trouble.
As for the reason he was so upset... it wasn't because of the events with the team, no it was because every single piece of candy he owned had been taken from him. I bought it all with my own money, so what's the issue! Back where he was from, he could literally drink chocolate syrup and nobody looked twice, but here... oh here! Here he'd gotten it all confiscated! Riko, while she had sort of become a sibling figure that he he would take over all of his current ones- only two out of the four others actually- Kalluto and Alluka he enjoyed, but Milluki was always involved when torture as a punishment or as training was called for ( though he had gotten to the point of where he could sleep through most of it, mainly to spite him ) and while Illumi had been nice when the boy had stuck with the family business and remained at home, as soon as he left and made a friend, his older brother was threatening to kill his best friend. Though as long as Hisoka was interested in him, he figured Gon was safe from dying.
Arms crossed tightly over his chest, head hanging slightly, an obvious frown set on his face, and eyebrows furrowed, the ex-assassin pretty much stormed down the street. He didn't care where he was going or who was in his path as he traveled there, and expecting pretty much anyone to move out of his way like they would have back at his place if they knew what family was, he ended up coming across someone who didn't. The last time this had happened, though they had confronted him and wanted him to apologize, their heads had quite literally rolled. If he had removed this guy's head, it would have been done with near surgical precision thanks to his nails and after the reporters would jump on it like the nosy things they were made out to be, the brunette would be able to trace it back to him and who knew what she would do? Apparently their morals were really different here as well. So with this in mind, he restrained himself immensely, instead using an insult he normally saved for Leorio because his reactions were always the funniest.. "Watch where you're goin', old man!" He snapped even though the blond that had bumped into him looked to be maybe in his late teens. He certainly looked pissed, but his lip was trembling and honestly it looked like he was going to cry in a moment or two. Symptoms of candy ( mainly chocolate ) withdrawal gained from not having eaten any for the majority of the time he was here. He'd have used that as an excuse, but the brunette currently giving him a place to stay would have probably compared it to drug addiction.
