It’s been several months since Nina defended the Rostro Racers in court, and Fledge City residents eagerly anticipate the next season of the home-grown streaming show hit: the magical girl sensation, Valkyrie: Sacred Feathers!
But when an on-set lover’s tiff takes a dark turn, Nina Aquila is tasked with defending Millia Nordin, the lead actress, in a murder case that defies explanation, even by the defendant herself.
North of the city, dissent grows as the Bikers of the Wastes are vanishing without a trace. Seeking answers, a lone rider saddles up for the long journey south, seeking the one man who she knows can help her.
With Millia in custody, tension on the streets of Fledge City rises as each night brings with it unnatural, unexplainable events; disappearances, explosions, tales of monsters sighted in dark alleyways. Set on a journey where present fiction echoes the truth of the past, can Nina find the strength buried within herself to search for answers, and rise as the hero that Fledge City needs?
Lore meets the law for a war-between-worlds, with Fledge City’s courtroom as the fulcrum about which fate will turn!
Feathers will fly, wings unfurl, and light will shine amid the darkness… But before that, there’s gonna be magic, monsters and a whole load of sparkles.
Valkyrie… Transform!

- Content warning
- NINA AQUILA: LEGAL EAGLE, CHAPTER IV: SACRED FEATHERS contains some content that may not be considered appropriate for all ages, and in some cases may not be safe for work. The game involves murder investigations, and although there is no graphic violence or gore, we would like to forewarn audiences who are particularly averse to themes concerning crime and murder that these are present within the story. There is some mild nudity, typically framed in a humorous/cute manner. There are two heavily veiled shower scenes. Several images exist of a character in poses & outfits that some audiences may find sexy/provocative.
