The Spectral Mink could be considered to have two high class affinities in both Space and Wind. They were well known for their speed. But, their offensive output was enough to make anyone go numb as well. Very few who had ever seen their Wind Spectral Scythes had ever lived to tell the tale.
Ryu immediately crossed this possibility off of the list. His spatial affinity was only average, and that was just considering his overwhelming comprehension abilities and sensitivity to energy. Objectively, if these things were ignored, his spatial affinity was nearly nothing.
This wasn't entirely true, considering every Heavenly Pupils wielder had a modicum of spatial qi affinity due to their Inner Worlds. But, compared to Ryu's other talents, he saw it as nothing even if it would be enough for a lower class genius to brag about for their entire lifetime.
