Why then is Mangekyou needed, if afterwards you don't even need eyes to manifest it? It seems to me that thus, other ways of manifesting Susanoo exist. It certainly seems logical to me that Susanoo is linked to Mangekyou (since the event is the same: the brain changes and creates a special chakra. This both activates the Susanoo KKG and the Mangekyou KKG). The question is: what is it that makes Susanoo require the Mangekyou?
