Sorry, my bad. I should edit charsheet to say his eyes are now dark green. So far it's unkwon that he does have true red eyes. It's suspected he likely manifests red eyes (the lesser kind) but it's uncertain. He does have the chakra network suitable for it but his gate has not yet been opened completely.<br/><br/>Maki indeed may know several Mibu clan techniques and Mibu clan has kind of disgruntled attitude about it but they do not mind it so long Maki keeps her discoveries to herself and to her own private research than publicly announce detailed records how their techniques work.<br/><br/>Anyways the style what we talked about is one master and one apprentice transfered technique (not neccesary by blood). But consider shinobi wars some kenjutsu master may had seen the style and mimicked or even branched it to different direction and renamed it something different. Knowing like D or C level techniques but developed own B and A class techniques (kind side branched style from the main true one).<br/><br/>Indeed, also Sharingan user may have catched the techniques and taught them to someone but consider it is indeed one apprentice and one master deal the chances to see it in action has been rare.
