rokugan- a doujutsu. it has the same power as the chakra armor in the naruto movie, it makes the user immune to ninjutsu and genjutsu. the only downsides are it doesn't make the user immune to taijutsu or bloodline traits and it makes the user unable to move or see for seven days and seven nights if it is overused. also, the user is immune to medical ninjutsu. it is sapphire blue with six black dots around the pupil. like the sharingan, it starts out with one mark and adds more as it gets stronger. the difference is it has six forms instead of three. also, after it is unlocked, it remains permanently active. it can only be gained by being almost killed by ninjutsu or genjutsu. it can also seal an opponents chakra and make them unable to fight. any genjutsu an opponent uses is reversed and any ninjutsu an opponent uses dissapates.
