Page "Ninja High School" Paragraph 3

The series plot started rather simply: Princess Asrial was sent to Earth to find Jeremy Feeple and marry him, an act that was described as required to ensure that their enemies do not lay claim to the planet.

Since Earth was a non-aligned world, anyone could claim it, and the Salusians were desperate to keep it from being used against them.

Ichi went to America to marry Jeremy as well, although her reason's for the trip were different, in order to become leader of her clan, her grandfather informed her that she had to marry the boy, the reason behind this is that Jeremy's mother was raised by this grandfather, and they wanted to be blood related.
