Any ideas or facts about how Kikashi obtained MS? This has been bugging me since it was first revealed.....Personally, i thin he had obtained the pre-requisites some how, upon Obito's death and after Rin implanted his eye. If Obito was his best friend, as well as Rin, i think he obtained the pre-requisites through their deaths and later unlocked it after Itachi trashed him in Konoha, having fully learned that it existed through that fight..(could be wrong there, maybe he already had knowledge of it beforehand i cant remember)
