Olivia Highland (オリヴィア=ハイランド Orivu~ia = Hairando) is a character mentioned in the Mitou Shoukan://Blood Sign series. She was Kyousuke Shiroyama's previous vessel half a year before the events of the series.[1]


Olivia is described as a twelve-year-old girl with bright blonde hair.[1]


Not much is known about Olivia's personality, though she seems a cheery girl going by her last conversation with Kyousuke. According to Aika, Olivia ignored her and clung to Kyousuke's arm with an innocent smile while muttering ‘Onii-chan’ in her sleep.[1]


Half a year before the events of the series, Olivia lent her body to Kyousuke Shiroyama as a vessel to pay the investigation fee needed to search for the mother she had never known. The two worked together for a total of three weeks, but after that she safely returned to the sunlit normal world, though her parting words left Kyousuke troubled.[1]
