Ren Nanase is a 22-year-old nurse at St. Juliana Hospital who stands out for being both bright and friendly. She's the first person Ryuji meets in the series and welcomes him as a friend and colleague. Her love interest, Naoya Ohkawa, leads to her involvement in match fixing, which becomes a source of blackmail against her. Despite facing mistreatment, Ren develops Stockholm syndrome and forms an emotional bond with her abuser. She is easily recognizable by her long hair, usually styled in a ponytail.
