Ringo Oginome

The target the brothers are ordered to watch. She was born on the same day her older sister Momoka died, which caused her family to fall apart, and she now lives only with her mother. She possesses a diary that belonged to Momoka that foretells future events. She started to believe that by turning herself into Momoka she could bring her family back together, often going to extreme lengths to have what is written there fulfilled. Despite Ringo's claims that she and Tabuki are destined for each other, she is astonished when Yuri makes her realize that she started harboring feelings for Shouma instead.
