Several adaptations of the manga have been released, including original video animations, light novels, and audio drama CDs.

In 2004, Central Park Media licensed the Finder series in English for North American distribution under its Be Beautiful Manga imprint.

[5][6] John O'Donnell, then manager of Central Park Media refused Libre's claims and felt that Biblos's original license agreements were still valid.

Finder was not listed among the assets, indicating Central Park Media no longer held the license.

[2][3][12][13] A light novel adaptation was written by Ai Satoko and published by Libre, with illustrations provided by Yamane.

A special anime adaptation of 'Target in the Finder' (ファインダーの標的) was recently released by ANiMix Project on February 29, 2012 - starring Japanese voice actors Tetsuya Kakihara as Akihito, Takaya Kuroda as Asami, and Nobuo Tobita as Feilong.
