During the investigation of Petenshy's poison, the two found Mieterman peeking into his flat but he quickly runs away.


Mieterman acted very irritably toward Naruhodō and Petenshy. He wore bright yellow and looked out of place comparatively.


  • Mieterman's clothes seem to resemble a Bumblebee, combined with Mrs. Altamont's appearance, this would make him the worker bee to her queen bee.


  • The names of Mieterman and William Petenshy were not given during Dai Gyakuten Saiban: Naruhodō Ryūnosuke no Bōken. However, the title of "Mysterious Man B" was given to Mieterman in the game's artbook, while Petenshy was referred to as "Mysterious Man A".[1] He is named in Dai Gyakuten Saiban 2: Naruhodō Ryūnosuke no Kakugo.[2]
  • "Decargo" is a portmanteau of dekai, “big” (でかい) and ago, “chin” (顎). “Mieter” most likely comes from “meter” (in this case, either the gas meter, or the meter in poetry). It could also come from "Mitta man", which could mean either "man who saw it" or "saw it all".
