I put the difference in the origins of the power of the equipment. The soul weapons the heroes and sovereigns receive receive their strength from the divine power of the gods; they merely have to unlock its strength by progressing through their Psalms and even at their base strength they're already Legendary ranked equipment.

Kichi's weapons, though, grow in strength in relation to his own. As long as he gets stronger, his weapons will too.
