Gyokushin Ryu

The second ninjutsu ryu in the Bujinkan system was founded by Sasaki Goemon Teruyoshi in the mid 1500. Not much is known of this ryu except that it is an Iga ninja school and concentrated more on the espionage side of ninjutsu, rather than the fighting side. It is also known for its use of sutemi (sacrifice) throws.
