FitGirl Repacks is a website distributing pirated video games.

The repacked games, usually limited to Microsoft Windows, are distributed using file hosting services and BitTorrent.

They are generally accompanied during installation by the song Tsuki Sayu Yoru by Hiromitsu Agatsuma.

The first one she shared was a repack of Geometry Wars 3: Dimensions on Russian trackers on July 6, 2016.

Her repacks grew in popularity; in 2020 TorrentFreak described her as "the best-known releaser on the internet".
