Secondary Rider ofKamen Rider Fourze. His real name isSakuta Ryusei, a member of the Anti-Zodiarts Union who also doubles as the rival and eventual friend ofKisaragi GentaroandKamen Rider Fourze. Unlike Fourze, his powers come from the M-BUSsatellitespace stationin Earth's orbit above Japan, which holds necessary energy for Meteor to transform. Cosmic Energy is received to complete Kamen Rider Meteor's transformation. However, if Ryusei is not exposed to this energy, he is not able to transform. After transforming into Kamen Rider Meteor, he says "Kamen Rider Meteor, your fate is mine to decide!", thoughYukiwill yell out "The Meteor is Here!" everytime Meteor arrives in his blue fireball form. His helmet is called the Star Face. By swapping the Meteor Storm Switch with the Meteor Switch in the Meteor Driver, then spin the fan on the Switch after activating it, he can transform into the stronger Kamen Rider Meteor Storm, gaining in both power and speed. After changing into Kamen Rider Meteor Storm, Ryusei says "Kamen Rider Meteor Storm, my fate will deliver a storm!". His helmet is upgraded into the "Starlight Face". In this form, he gain the access to a new weapon, the Meteor Storm Shaft, which is a gun rod-like weapon.
