Kiro activated lightning manipulation, people would've thought it impossible, but that turned his eyes bluer. He had bits of lightning zapping through out his entire body, making his brown skin more prominent.
Of course nobody could really see his skin, but the eyes, underneath that dark hood they shone brighter than a full moon on a dark night.
People had one thought in their minds, 'god of lightning.' Which was a bit of an exaggeration, but it was rare to get such an elemental manipulation in the game, so they weren't far off either.
It was a shame that he could only use his lightning skill in such a mediocre way. He could make himself faster, he could coat lightning with Ryu, he could turn foes to charcoal.
But lightning manipulation was much more than that. It had more to offer, and unless Kiro figured it out himself, the skill would stay hidden.
