German Tanteidan MarinGumi: Maruhi Jigomar Sousa File

German Tanteidan MarinGumi: Maruhi Jigomar Sousa File (also known as Jaaman Tanteidan: Matonarikumi) is an adventure game from Bandai that uses the license of a TV show that was also the basis of Bandai's earlier action game Omoikkiri Tanteidan Haado Gumi: Matenrou no Chousenjou. Both games feature teams of schoolchildren detectives as they hunt down an elusive thief in a mask and cape.

The game follows a sub-genre of Japanese adventure games that include a top-down RPG style world map to walk around on, rather than simply selecting destinations from a menu. Otherwise the game is similar to other NES Portopia/Tantei Club-derived detective adventure games; the player must search for clues, talk to witnesses and suspects and solve inventory-based puzzles in order to proceed.
