Riku has a bright and cheerful personality and is able to become friends with anybody. He is very athletic and has good motor skills but only has an average cardiovascular fitness. Riku has also been recruited for several other clubs (specifically basketball, volleyball and table tennis) in the school, more for his speed and agility rather than his ball skills. He has great acceleration and poor parkour skills because while he can jump and hurdle, he can never land safely.
