User blog comment:Gundam Legilis/Volume 1 Weapons In Depth- StormFlower/@comment-24994749-20140619233640

I will admit that, when compared to other weapons on the show, Storm Flower isn't very "impressive".

That said, it's not like we have seen Ren use them a lot. The blades might be transformable in some way we don't know or haven't been shown. It did look like he defeated King Taijitu almost completely with his aura and hand to hand.

My personal headcanon is that when he was on Lower Combat School and they told him he had to design and build a weapon to fight he came up with the quickest solution possible by modifying an existing weapon in the market because he isn't really one to fight with anything more than his aura and semblance.
