Otherwise known as Denpa Ningen no RPG 2 in Japan (the sequel to the first game, The Denpa Men: They Came by Wave or Denpa Ningen no RPG).

I have tried looking for a rip of the soundtrack these past few days, but no luck, except for a few tracks that have been uploaded on Youtube. I'm not sure if there was an announcement regarding a release of the OST like they had done with the first game, but it would be great if anyone has heard of such a thing.

The game was localized and released in the US for the 3DS on May 30, 2013.

I'm not sure what the order of an official track list would be, but I'll go with what I can remember hearing in the game (using some of the names from the Youtube videos):


Title Theme
Banner
Digitown
Vs. Common Enemy
The Denpa Men House!
The Spirit Shrine
The Store!
The World of Denpa Men (Overworld)
Sailing the Sea (Overworld)
Sailing the Dark Sea (Overworld)
Boss Theme
Vs. Coliseum Participant
Evil Witch

There's probably a few that I missed, but part of the game reuses soundtracks from the first one in a few dungeons and other things (such as catching Denpa Men in the Radio Tower, clearing a dungeon, etc).
