Need Help identifying an old game.

I have this game in my memory from old old days. I’ve been looking for its title for over eight years now.

I know it was a Turnbased eastern RPG on the Dreamcast. I know it was 3D.

The only two clues I have in what it is are that there’s a recurring ‘super bad devil/evil Satanlike guy’ and each major boss fight was a different limb of this bad force. The bosses were named like, “>’s Eye” or “>’s Hand”. One of the cool things about those bosses were they weren’t of the same being, the Hand boss was mechanical/robotic and the Eye boss was straight up an organic eye.

That’s the biggest piece I have, but I know another plot/story thing. After a short way through the game, this wimpy kid you had in your party for a while ends up becoming the king of a small village. I think he had red hair.

Also, after a certain point on the story you learn a powerful magic/sword technique that splits the ground and does 999 damage to every enemy.

Any ideas? I’ve been dying to know, holy crap.
