有栖 梨奈

Yua's older sister who is a writer. She is often running around the town looking for interviews, mostly due to the strange events (the shooting star and the school being replaced) in the city. While she is very nice, Rina is actually a very huge fujoshi, and loves to pair Takaya up with Adam and sees everything around her through her "BL Vision", which is why Takaya has a hard time and trouble corresponding.
