This article is about a/an ranger in Kanjani Sentai Eightranger, a show unrelated to Super Sentai or Power Rangers, but having similar traits.

Black Ranger (Yu Yokoyama): In the skits, he was previously the "Green Ranger", but his Ranger Color was changed and so was his name. His characteristic is "Friendly". He's known to sulk a lot. His strong point is the punchline, in which he uses this against the B.A.D Group's adlibs. In Kindergarten his nick name was "Kimi-kun".

In the film's more serious take on the Eightrangers' story, he has an gambling addiction. He is also the central figure in the film's version of the team as opposed to the Red Ranger.
