Sonobe Sora

She has secretly been in love with Makio since they first met, but has refused to act on her feelings due to the age difference between them. Her aloof demeanor when interacting with him is due to embarrassment rather than dislike. She has tried many different things to attempt to overcome this longing, but they have all only resulted in her adoration deepening further. Her concern for her sister and Makio's well-beings eventually pushes her into uncovering Seiji's plot, and the actions she takes to protect them both drive much of the later parts of the story.
