A childhood friend you've been close with since you were little. In the winter of his 18th year, his vision suddenly became blurred. It turned out to be a disease that will leave him completely blind within a year. Along with the vision loss, he suffers from fatigue, shortness of breath, numbness in his limbs, chest pain, headaches, and nausea. Lately, he seems to have lost the will to live, often spacing out even when spoken to. The once energetic Ritsu has become negative and fragile.
