Ryuusei Shidou is a supporting character of the Blue Lock.

Shidou unlike most forwards has no concrete dream of becoming the world's best striker but rather seeks to enjoy life to the fullest by playing football.

Out of the original 300 forwards chosen to be apart of the Blue Lock Project, Ryuusei is an ideal candidate for the type of striker Ego strives to create and after the Japan U-20 match, Shidou is ranked as one of the top players in Blue Lock.
