Riki Naoe lost both parents around age ten, resulting in depression and a concurrent narcolepsy diagnosis causing uncontrollable loss of consciousness. Kyousuke Natsume invited him to join the Little Busters, a group formed to "preserve justice" and "fight the enemy," helping him emerge from depression and befriend Rin Natsume, Masato Inohara, and Kengo Miyazawa. Physically, Riki possesses a weak build and girlish appearance, standing 166 cm tall and weighing 54 kg, making him the weakest original member. Despite this, he demonstrates straightforwardness, common sense, compassion, and dependability, often supporting friends through personal difficulties. His narcolepsy frequently manifests after mentioning it, impacting daily life and limiting opportunities. Within the Little Busters, Riki serves as a unifying figure, successfully recruiting new members for their baseball team when others fail. This involves deepening bonds with female classmates by assisting them during personal crises, uncovering their stories, and earning their trust. His intelligence and reflective nature allow him to contemplate philosophical concepts, including the "secret of the world" referenced in mysterious notes Rin receives. Experiencing repeated cycles in a constructed world designed to strengthen him and Rin, his combat statistics and attributes gradually increase with each replay, eventually surpassing other members. During these cycles, he sometimes perceives world abnormalities, like time stoppages or unnatural events influenced by Kyousuke, though the world's true nature remains hidden. In the Refrain scenario, Riki reforms the Little Busters after Kyousuke's harsh methods psychologically damage Rin. He heals Rin's trauma, uncovers the personal struggles of Masato and Kengo, and draws Kyousuke out of depression, reuniting the group. This reveals the "secret of the world": the constructed reality mimics the semester leading to a fatal bus crash, created by Kyousuke and the others to help Riki and Rin gain strength to cope with the impending tragedy. Learning of the accident, Riki resolves to protect everyone, using intelligence and collectedness to alter events in the real world. In later timelines, he becomes Rin's boyfriend, with their relationship evolving romantically after a proposal. A future scenario depicts him fathering a daughter, Kaya Naoe, with Kudryavka Noumi. His physical capabilities include transitioning into a W-sitting position. *Citations:*
