Holly Joestar-Kira

A world-renowned opthamologist from T.H. Medical University Hospital, associate professor at Morioh's T.G. University, the mother of Yoshikage Kira, and direct descendant of Johnny Joestar, Yasuho and Jousuke believe she is the key to discovering the truth about his past. Yasuho manages to find her in Morioh hospital's patient wards, but the nature of Holly's stay is not clear. After Yasuho's presence and lack of any relationship to Holly is discovered by security, Yasuho is removed from the hospital but not before Holly recognizes that Yasuho has developed a Stand that she believes will help her son. She shares her name with Part 3 Stardust Crusaders character Holly Kuujo (née Joestar), mother of protagonist Joutarou Kuujo.
