Kairi's older brother who works in the video game industry. He serves as a male counterpart to Sae, only he is significantly more dangerous. Ryo is in love with Misao, and dated her briefly, but Misao broke up with him because of his cold and manipulating attitude which is revealed when he smacks Sae after hurting Misao.
Sae meets him and quickly falls for him because of their obvious similarities, though Ryo barely takes the relationship seriously and treats Sae poorly. When Sae tells him she is pregnant with his child he gives her money. Though Ryo feels touched by Sae when she tells him she wants to make a family with him that will love him. Though after they find out Sae had a false pregnancy, the two split. However, Ryo stills feels touched and seems to be interested in having kids.
