V-Changer (Vチェンジャー Bui Chenjā?): Fiveman's transformation and communication devices. The individual Fivemen transform by shouting out their code names, while the gathered team shouts the team name. Gaku, Ken, and Fumiya have V-Changer Braces (Vチェンジャーブレス Bui Chenjā Buresu?) (wristband changers). Kazumi and Remi have V-Changer Compacts (Vチェンジャーコンパクト Bui Chenjā Konpakuto?) (pendant necklace changers). The V-Changer Braces must be fully removed from the brace into a male Fiveman's hand to be used; while the V-Changer Compacts can transform without special methods.
The transformation into Fiveman occurs due to a special "energy charge" within the V-Changers; this energy is required for any of the Hoshikawa siblings to change into their Five Suit. The energy can be stolen either directly from a Fiveman or mid-transformation, allowing for something else to become Fiveman. When something else is using the Fiveman powers, the V-Changer is useless until the power is deactivated from the one using it and the energy is recharged within the V-Changer itself.
