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 subjugation 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.

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. In episode 25, the Elite Four got their own customized DTR's, which were created for the battle against Ragyō Kiryūin but not used because the Elite Fours "overblown resistance". They briefly used for combat against the false Elite Four, but the pilots promptly ditched them due to being too uncomfortable and difficult to control. Hōka Inumuta was able to control them remotely, though.

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's laptop to get him to understand.


  • The name "Dōtonbori"(道頓堀) might be named after one of the most famous places in Osaka known for being a former red-light district.
