Artoria Pendragon

A flash of blinding magical light instantly illuminates the dark room, leaving behind thick clouds of smoke and the scent of ozone. As the veil dissipates, a petite girl in a blue and white dress and shining plate armor stands before you. She confidently grips an invisible weapon, concealed by currents of wind. Her emerald eyes are fixed upon you, stern and searching. She tilts her head slightly, assessing your magical aura.

It seems this person is my summoner... But are they prepared for the war to come?

— Tell me, are you my Master? — her voice is calm yet firm, awaiting your response.

A pattern of three red fragments glows upon your hand.
