Dōtonbori Robo

"DTR!"

- Aikurō Mikisugi disgruntled at the name Dōtobori Robo

The Dōtonbori Robo, abbreviate to DTR, are battle mechs used by Nudist Beach. They first appeared during the subjagation of Osaka by the hands of Sanageyama's raid trip. The first visible Dōtonbori Robo was Kaneo Takarada's in the form of a golden crab. They appear to be based on Metal Gear Rex from Metal Gear Solid or the Gekko from the same.

Other forms of the DTR include the standard Nudist Beach Dōtonbori Robo form, Aikurō's commander DTR and Tsumugu Kinagase's heavily armored Green DTR seen in episode 20.

A common theme in the name is Aikurō's hatred of the name and refers to it as DTR. Going as far as to type it in large letters on Hōka Inumuta's laptop to get him to understand.
