Misa was a hospitalized kid facing serious surgery she was terrified about—convinced she wouldn't make it through. Usagi, picking up on the fact that she was huge into the Three Lights, managed to get Kou Taiki to visit and lift her spirits. It turned out to be exactly what both of them needed. Taiki had been struggling with doubt about whether their music's message would ever actually reach their princess, but meeting Misa changed that. When she listened to their songs, she'd see the princess in her mind, and that simple connection reinvigorated Taiki's faith in what they were doing. He encouraged her to find the will to survive, and she got the strength to go through with the surgery.
