Aura Changer (オーラチェンジャー Ōra Chenjā): The two-piece transformation brace of the five Dairangers which also sparks their Chi. It is activated by extending a key from the right piece, called Aura Gather (オーラギャザー Ōra Gyazā) and inserting it into the left piece, called Aura Spreader (オーラスプレッダー Ōra Supureddā). After this, the Aura Gather sparks the energy that is concentrated and condensed into the Aura Spreader, immobilizing metallic ions in the air, materializing the Dairen Suits, and thus transforming the user into a Dairanger. The transformation call is "Chi-Power Tenshin, Aura Changer!" (気力転身! オーラチェンジャー Kiryoku Tenshin Ōra Chenjā). The left piece can also be used as a communication device. Whoever at the headquarters can communicate to the Aura Changers through a two-way talk radio.
