Just an idea that actually could never happen. This is the extremely shy son of Kinashi and Sakura. Ryouchi hardly ever speaks and clings to his mother more than his father. Even though Kinashi tries to get closer to his son Ryouchi ends up shrinking back as if he were possibly afraid of his father. Kinashi can't figure out why but he and Sakura are very concerned. Once again this is just an idea. The reason why this will never happen though is something you'll have to find out in the manga. *btw, Achiro was Kinashi's last name before it was changed to Eizokusei when his stepfather married his mother. He changed it back after he was 18.
