Solty Rei (2005)

In a city blanketed by a surreal aurora-like force field, Roy Revant, a grizzled bounty hunter, haunts the streets with a heart hardened by a past consumed by the Blast Fall, a calamitous radiation disaster. Amid the spectral ruins of a class-divided world, Roy's life is a shadowed quest for his missing daughter Rose, a void filled with desolation and silence following the death of his wife due to radiation. Into this world of grey and despair, a bolt of light unexpectedly strikes – a young girl known as Solty, a robot with an erased past and an unmeasurable heart. As she crashes into Roy's life, his resolve to keep the world at arm's length starts to falter. Despite his initial reluctance, he adopts Solty, granting her a name, a home, and an unsuspecting place in his mission to find Rose, now entangled in the city's hidden web as a revolutionary outlaw. Their journey together unravels the city's veiled secrets, deeply entrenched in Solty's forgotten past and Rose's current rebellion. As the bond between Roy and Solty tightens, the stoic bounty hunter finds himself opening his heart to the devoted robot girl, who views him as more than just a guardian, but as a father. In this post-apocalyptic world, their paths are intertwined with mystery, rebellion, and the quest for familial reunion. Their lives, once marked by loss and oblivion, now pivot towards a future shaped by uncovered truths, the power of devotion, and the pursuit of redemption. What fate awaits Roy and Solty in their quest is a tale as enigmatic as the city they traverse.
