Mūn'ai

Mūn'ai is a Dojutsu, the only weakness to the bloodline is that it relise on the moon being out but once the moons out, one can cast a world wide Genjutsu on the world, even if the sun begins to rise the genjutsu stay's in effect until the user releases it.

While the Genjutsu is in'a effect; anything that happens does not happan in real life, for example: If you are killed by someone inside the Genjutsu, then when the effect is canceled, you will wake up as if it never happened in the first place. Also once the Genjutsu is active, the user 'If trained well' would only need a sliver of there chakra to maintane the Genjutsu.

It should also be known that the Eight diffrent cycles of the moon cast diffrent Genjutsu.
