- "Cell Burst!"
- ―Finisher announcement[src]
The Birth Driver (バースドライバー Bāsu Doraibā) is a belt that enables the transformation into Kamen Rider Birth, created by Doctor Maki as part of the Kougami Foundation's Medal System. After a single Cell Medal is inserted into the Birth Slot (バースロット Bāsu Surotto), and the Grap Accelerator (グラップアクセラレーター Gurappu Akuserarētā) knob is twisted, the belt's Receptacle Orb's Trancer Shield (トランサーシールド Toransā Shīrudo) is opened, encasing the user in the energy-based Cell Reactor (セルリアクター Seru Riakutā) as the Kamen Rider Birth armor forms around him. After inserting another Cell Medal and turning the Grap Accelerator again, Kamen Rider Birth can summon one of the Birth CLAWs units. By inserting two more Cell Medals into the belt, Kamen Rider Birth can initiate a Cell Burst (セルバースト Seru Bāsuto) attack.
