Holy Kujo

Holly Kujo (Horī Joestar ホリィ・ジョースター), is a minor character appearing in Part III: Stardust Crusaders.

Appearance/Personality
Holly's sweet charm is known by all. She believes in her son deeply, proud of the compassion that he has despite his hard shell. A woman who loves her family, she will deliberately lie about her illness so as to lessen their worry.

Stardust Crusaders
Holly is introduced as the loving mother of Jotaro Kujo. When he locks himself in jail, claiming to be possessed by an evil spirit, Holly calls her father, Joseph Joestar to see him. Joseph tells Jotaro and Holly that Dio Brando had acquired the body of Jonathan Joestar, and with it, had somehow developed a Stand ability. Because of this, all of Jonathan's descendants had also developed a stand, the "evil spirit" Jotaro mentioned. Holly eventually develops one too, but doesn't have the strength to support it and falls ill. Holly's ailing condition becomes the catalyst for Jotaro and company's quest to Egypt, as the defeat of Dio would stop Holly's stand of showing itself. At the end of the adventure we see her back on her feet and once more the loving person she was.

JoJoLion
Holly is the mother of Yoshikage Kira in the alternate universe, making Kira of the alternate universe a direct descendent of Johnny Joestar. Holly Joestar Kira is revealed to have been an ophthalmologist who worked at the T.H. Medical University Hospital from 1998-2008 and is currently a guest professor at T.G. University. As of 2011 in the alternate universe, she is shown to be a patient at a hospital.

Stand
While Dio was alive, she developed a Stand but was incapable of using it both due to her gentle nature and not having the need to battle or fight.

Trivia

 * Her Japanese name is "Seiko" (聖子), meaning "holy girl". This is derived from a transliteration of her English name "Holly".
 * Holly's Stand is the only one in the series to inadvertently cause harm to its user. Her stand is also one of the only 'Unnamed Stands' in the entire series and it has no obvious abilities (besides causing harm to its user).
 * At the beginning of chapter 120, Holly is seen singing to herself. The lyrics are likely from the Kylie Minogue song "The Loco-Motion"
