A high school girl is transported to another world, in a typical fashion.

However, her destination is inside a spaceship about to be engulfed by a white dwarf. There's no magic or swords, but with a Kansai-dialect-speaking AI, Osaka, as her partner, she travels through space, fueled by 'magic power.'

She's targeted by space pirates and ends up being pursued by the Imperial Army.

She rescues a princess with a past whom she picked up along the way, then, aiming for the colony ruled by the grandparents of the princess's mother (the Empress), she survives with the motto of 'never give up, never die.' Apparently, she also finds herself embroiled in a royal family power struggle.

The climax is a fleet battle!!
