Shows like Kamen Rider Kabuto

An alien species called Worms threatens the city after a meteorite crashed into Shibuya seven years ago. An organization called ZECT has been developing zecters that can turn its users into masked riders in order to fight the Worms. One of the riders is Tendou Souji who manages to be chosen by the Kabuto zecter and sworn to kill all Worms that otherwise threatens humanity.
