day whisk her away from the clutches of
ennui, she whiles away the days until a
tidal wave sweeps in the opportunity to
make her dream a reality.

Trailer Teaser Text

This text only appears in the voiced trailer pop-up window.

The vast blue seas of Auguste have long been a
paradise to the lives beneath their waves.

But paradise isn't perfect—at least not to one
particularly bored denizen of the deep.

Believing that a Prince Charming will one day
whisk her away from the clutches of ennui, she
whiles away the days until a tidal wave sweeps in
the opportunity to make her dream a reality.

Next up in Granblue Fantasy,
Mermaid Princess and the Sea Legend

She has but one wish: to go on land and walk
side-by-side with her Prince Charming.
