Riki is the male protagonist of Little Busters! and is the role the player assumes in the game. He is the fifth member of the Little Busters, and of them, he is seen as the weakest due to his girlish appearance and physical build, but he is the only one that is straightforward and has common sense among them. His parents died when he was very young, and around the same time he was diagnosed with narcolepsy. The world Little Busters! takes place in is actually an artificial one made for Riki and Rin so that they may grow stronger; in the real world, most of the characters were in a bus accident and only Riki and Rin survived.
Riki is the weakest of the original five members, but his starting attribute values increase on each play through and can eventually match and outgrow Kyousuke's statistics. He also has above-average values on concentration and judgment attributes, so coupled with some agility and reflex enhancing accessories, he can be a force to be reckoned with during battle. The player can raise Riki's statistics faster by hitting the balls to Kyousuke during baseball practice, which is needed to prepare for Mask the Saitō's battle. It is not very useful during the baseball game, however, since he must play as a catcher. If Riki manages to get Mask the Saitō's mask accessory, it will raise all of his statistics by fifty during battle, making him almost invulnerable unless he gets a sub par weapon.
