Astronomical Namesake: Capricorn Place of Origin: Boston, Massachusetts, USA Birthdate: January 12, 1909 Age: 19 Height: 162 cm (5'4") Weight: 42 kg Blood Type: AB Fenics Unit: AT-05D "Silent-Star" Height: 4m Weight: 4,5t Color: Baby Blue Weapon: 2-Barrel Chemical Launcher x2 A frail young doctor who wears glasses and is sometimes confined to a wheelchair. In the beginning of the game, she serves as Shinjiro's comfort when he's feeling troubled. The group learns that Diana is Sunnyside's niece and that Diana is slowly dying. Diana's spiritual power is so great that it is physically damaging to her body, which is the cause of her poor health, made worse by her already frail body. Because of this, Diana decides that she cannot fight the inevitable and wastes the rest of her life waiting on death. Diana extends this philosophy to the lives of others as well; her spiritual power allows her to sense when people (and animals, such as her beloved birds) will die, and she believes that nothing can be done to change this fate. It is not until Shinjiro and the others show her that she can fight her fate that she decides to walk and help the Hoshigumi. She even decides to undergo surgery to save her life at the end of the game (which, as she shows up in the OVA, is successful).
