Something readers should take away from this part of Ishikawa's story is how a persons environment has a direct affect on their character. Some will argue that one must rise above such things but the reality is that most do not and in all honesty shouldn't be expected to. The existence of such oppression is what matters. Life shouldn't be a series of trial by fire. Are we not evolved past this? Are we all still primal beasts unable to transmogrify our society?
