This a question I would like to ask does genjutsu including tsukuyomi have any efect on Sasori because tecnicaly sasori is a stump(that organ I don't know how's it called) atleast the live part of his body,so what do you think
yup yupI think it can, if the enemy has a brain and has chakra. Genjutsu manipulates the flow of chakra in the victim's brain, creating a problem in their senses.
