Itō Ryūsuke (伊藤 隆佑) is the only person to both compete in and announce a SASUKE tournament. He competed only three times, making it to the Jumping Spider twice, both times failing to get his legs into the walls. In SASUKE 22, he went out on the Log Grip and also did not wear a number in the tournament.
In 2010, he was named as the #2 announcer for SASUKE 25, replacing Satō Fumiyasu, who moved up to the first announcer position since Ogasawara Wataru's was unable to attend.
Itō would return in SASUKE 31, replacing Ishii Tomohiro as the #2 announcer, who could not announce SASUKE for unknown reasons. Ironically however, he was replaced in the following tournament as well, by Sugiyama Shinya.
Itō was also the announcer in KUNOICHI 2018, replacing Sugiyama Shinya from the previous two tournaments, primarily from BLUE to Final Stage.
As a commentator for TBS, he has announced several Monster9 events, including the Pro Sportsman No. 1 2010 Monster Box special. After Sportsman ended, he later returned as the announcer in the reboot show Sports Danshi Grand Prix since the third tournament, a position which he has continued to present day.
