I agree with Toturi. Also, the Denarians' superior physical powerset would be fairly useless most of the time. The Toughness and Recovery powers get ignored by the Swords, and the Strength powers only matter if they can land a hit. Thanks to high Weapons, True Aim, Righteousness, and bucketloads of fate points, that should very rarely happen.
But I wasn't satisfied with that explanation, so I made a stronger version of Shiro. I wanted him to deserve the title of "world's greatest swordsman". So, here it is:
