Was "doing the best one can" working? No. God no. But it was slowing the bleed, and that was all that little people like Sho and Hiesin were able to do. Even if Shosuke gained complete control over the Yamamoto, they were one family amongst hundreds within the village system, and far more were playing selfish games for their own short-term gains than were trying to help others.
Hiesin was right, even if he hadn't said it out loud. Every year, more people turned to banditry or criminality because they had to, because more and more money that should be given to the people was taken by the rich. The world was rotting and falling apart, but there were still things that people could do to help others.
If believing that one could still help even in the modern world was idealism? Well, call Sho an idealist.
That said, that idealism and desire to help others was being tested here, as he turned the corner and looked at the mass of people bullying the smaller, more fragile-looking one. Even though he had never seen it directly before, he still recognised the Ryujin symbol from the warnings that he had been given by his family.
Medical caravans ransacked, doctors assaulted, supplies stolen, and all for the benefit of this one family. Now, standing before him, they were bullying someone who just wanted to sell their wares to the village? Sho wanted to throw himself head first at them, but he worried that doing so might get the person they were harassing caught in the crossfire. God knows that none of his techniques were particularly discerning.
Still, that didn't mean that standing back and letting it happen was acceptable. Instead, more mundane methods were called for in this instance. Taking a second to look around, Sho found what he was looking for - a small, sizeable rock, laying on the side of the road. It looked like it had once been part of a boundary wall or some other construction but had long since been left behind or fallen off of a cart.
Picking it up and taking a moment to test its heft for himself in his hand, he then turned around without warning and used the best of his strength to throw it, hard, at the back of one of the Ryujin's heads. Not hard enough to crack the bone or kill the man, but definitely hard enough to hurt, like a softball cracking into the back of their cranium.
"Hey, dumbasses! The fuck you think you're playing at? Leave the kid alone or I'll rip your throats out with my teeth!"
Sho's voice had drastically changed from the way that he had sounded earlier, speaking with Hiesin. The intellectual, scholarly tone was dropped, and instead it was an approximation of a thug's. Rough, coarse, deep, with a believable, threatening sneer in it. It was hard to believe in that moment that this guy was a doctor or had been speaking so feverishly about the need to help others, it was more believable that he was some sort of lowlife.
"Unless you wanna make a fight out of it, ya dumb bastards."
Sorry Hiesin, it seemed he didn't take the time to pen out their approach.
