The Climax Cellphone K-Taros (クライマックス携帯ケータロス Kuraimakkusu Keitai Kētarosu) is a special cellphone that was formed from the sandy remains of the Tarōs upon reacting to Ryotaro Nogami's emotions connecting to the Taros in the afterlife. Each of the buttons on the keypad correlate to a phrase that allows Ryotaro to call up one of Tarōs. Once attached to the Den-O Belt and the code 3-6-9-# is entered, Den-O can transform into Climax Form. The K-Taros can also summon the DenKamen Sword to evoke Liner Form. It can also be used as a normal cell phone, often being used to communicate with the Den-Liner crew.
