User blog comment:Gundam Legilis/Volume 1 Weapons In Depth- StormFlower/@comment-24231452-20140621131627

I feel like Ren is a character who uses his own physical strength and aura and is much less dependent and caring of his tools. Hence, they are not as impressive as other weapons.

He is a polar opposite to Ruby in that sense, and Ren may have a stronger aura than we realise because of his lack of need for his weapons to be powerful.
