Misa
Misa was a young girl hospitalized with an unknown, but serious, illness in episode 185. She was afraid to have surgery, because she didn't think she would survive it. Usagi, knowing that the girl was a big fan of the Three Lights, brought Kou Taiki to visit in an effort to cheer her up. Though Taiki was despairing that the message in their songs would reach their princess, he discovered that when Misa listened to the Three Lights' music she would see an image of the princess in her mind. Because of this, his own resolve was strengthened and he encouraged her to have the will to survive. Wikimoon
