I have a theory: Hiro’s father is the actual hero of this series.
Let’s look at the problems this village has: It is populated entirely by wolf creatures masquerading in human form. They can normally get along quite well, but when they come into contact with humans, they can go a bit bonkers — this is because humans give off a pheromone that drives the wolves into fits of sexual madness, which most likely will end with the poor human being eaten from head to toe, because food and sex go hand-in-hand. (Plus, if there is anything “Little Red Riding Hood” has taught us, it is that wolves like eating humans. Old, young, doesn’t matter. They are delicious.)
For whatever reason, Hiro gives off a pheromone that is a hundred times stronger than the average human — he is sort of like the Char Aznable of Ookamikakushi, except Hiro makes the wolves’ eyes glow red instead of a Gundam. Anyway, the village is split into two camps regarding these events: One side — apparently led by Nemuru’s uncle — wants to find a way to leave peacefully with the humans through finding a cure (or, at least, a suppressant) to the wolves’ condition. The other side wants to kill the fuck out of Hiro and continue on as if nothing ever happened.
These are the facts.
