This might be sappy... but this manga, aside from being well drawn and written, might be one of the most motivational things I've read.
Just like the MC I feel silly for saying it, but watching him crawl out of the depths of his own personal despair via the motivation he derives from wanting to better these villagers their lives; I in turn feel a similair motivation vicariously through him..
This, far from the more common shallow escapism many fantasy manga offer, begets confrontation with oneself..
At least, for those who resonate with the MC's state of mind..
