Regret, no Inari ever felt regret until this one. Its the regret of past mistakes, of making bad decisions and wonder of what if. Infiniari has never felt regret on the part of his decisions. Like all the other Inari he is selfish an self absorbed. This Inari actually felt love and affection for someone else. These two things makes him incompatible. As it would fill Infiniari with these emotions, it would likely destroy him.
