Lots of people say that Haruko is young. But he only looks young, he hasn't changed looks since he was twenty, even though he is around thirty now. With very long black hair, and black eyes. With dark grey steel, and black capes, belts armor he is wearing daily.
He shows mercy for hes people, that deserve it and is against execution to people who don't choose it, he let's people live in prison, than get punished with death or pain.
This King loves Artillery, that's why he is mainly focusing on wood production in Kingdom.
