The Nega Den-O Belt (ネガデンオウベルト Nega Den'ō Beruto) is Kamen Rider Nega Den-O's transformation belt. It is affixed with a device known as the SetTouch (セタッチ Setacchi) in the Terminal Buckle (ターミナルバックル Tāminaru Bakkuru), which can read a Rider Pass (ライダーパス Raidā Pasu) and the Imagin contained on it. When the Rider Pass is swiped across the SetTouch, a transformation can occur. The belt has four buttons (red, blue, yellow, purple), but these are not used as the SetTouch is already a shade of red. It is also used to activate the primary finisher, Full Charge (フルチャージ Furu Chāji). Unlike the voice on the original Den-O belt, this version has a distorted voice.
