There are no 'hard' bosses in most rpg games... a simple way of beating most of them is just to train yourself to the maximum level and they can all be taken down easily...
As to Soul Blazer... i know nothing about Jap and i had the Jap version of it (it's called Soul Blader there)... i had to play through the whole game without any game guides, only the instruction manual . It took me A LONG TIME to beat the game but i'm pretty sure i beat(and found) the first boss on my first time playing it.
Ehh.... no hard bosses is RPG games my ass... anybody here played Dragon Warrior (NES) It's damn near impossible to get above lvl 60, and even then killing the Dragonlord was a total bitch.
