Ninja Of War wrote: Genjutsu are mental jutsus. Meaning your mind is being affected. So for bringer of darkness (BoD), literally the signals of the target's brain to and from the eyes are being blocked. There is physically nothing wrong with the target's eyes, they just can't use them. IT was a visual genjutsu, but BoD isn't. I also initially thought that it would not affect dojutsu users, but it is described as guaranteed to have this effect. To say otherwise is to disregard facts. If it'd be so easy to block the enemy's doujutsu with the BoD, Hashirama wouldn't have to battle Madara 24 hours non-stop to bring him down, he'd just use the BoD to neutralise his EMS abilities and stun him with some powerfull jutsu afterwards. So it's reasonable to assume the BoD is actually ineffective against someone with MS or the doujutsu above it (namely the Rinnegan).
