These are pretty cool animoose, I suppose

Well Shu's character was a metaphor for... Well, people who essentially do exactly what he was doing when presented with such brutality as the various themes in the setting. He was meant to be unchanging, and naive, until that moment with the kendo stick (which is where that metaphor, as well, comes to fruition).

That's how I see it at least. His character was intended to be a tool to cultivate a certain outlook, and pitch it into the mess that is the setting.
