If you look around the reddit, the last of three great youkai is Ootakemaru, the oni who want to marrying Suzuka: http://yokai.com/ootakemaru/

Basically Sutoku listed as three great youkai of japan is wrong since in the original/old source (japanese) its mentioned Ootakemaru. Sutoku have his own group called three great onryo of japan (http://yokai.com/onryou/) alongside Taira no Masakado and Sugawara no Michizane.
