I'm talking about those moments in the series when his eyes become golden and Battousai-like like when he managed to stab Heathcliff, cut through all of those Guardians protecting the World Tree with that blue aura move and when he beat Death Gun with Double Circular. I don't believe this is ever explained. In fact, I've read that Asuna has done something similar in the 1st Progressive novel, only her eyes became red.
