Fnia After Hours 'link'
The "Anime" units were a failed experiment by a rival entertainment company (Afton Robotics' competitor, "Dream Weaver Inc."). These units were designed to be companions for terminally ill children, using anime personas to grant final wishes. However, the project was defunded. The units were left in "After Hours Mode"—a limbo where they still believe they are fulfilling their original purpose.
