Princess Arthur is an otome visual novel video game developed and published by Idea Factory.


One king left this world.

In this realm, where kings have traditionally been chosen by the Holy Sword, it came time to hold a new Choosing.

Out of the many people who sought to draw the Sword, only one succeeded.

A peasant girl, neither knight nor royalty.

The girl remains confused about everything, but the legendary wizard Merlin persuades her to take up the crown. Then she meets the Knights of the Round Table.

The girl sets out to battle for the first time in her life.

She grips the Sword tightly in hand, still not knowing why it chose her. Tears are in her eyes.

The girl learns what love truly is.

The threads of fate twist around her, but through it all, she holds love dear in her heart for one man.

The girl takes up the Sword…

…the Sword that will allow her to cut a path for her beloved’s destiny.
