Summary
As the youngest of George Miyagusuku’s three adopted children, Riku is the younger brother of Kai and Saya. He is characterized by his kindness and intelligence, with a particular passion for cooking. His gentle demeanor has a notable influence on the reclusive Hagi, who is coaxed out of his isolation when Riku offers him a plate of food and invites him to join the group. In return for this kindness, Hagi teaches Riku to play the cello and later saves him from severe injury after Riku falls from a moving train.
