Though Naoto initially comes off as a rather impassive and indifferent person he cares for his friends and Starlight School. He is shown to be mature and wise as he commonly gives advice to Ichigo and her friends. He is kind, empathic, sensible, and down-to-earth, but can have a temper at times. He has stated to not be interested in any of the students at Starlight School due to them being kids to him. He is also very blunt and straightforward and doesn't hesitate to say his thoughts; even if no one's around to hear them. He's also highly perceptive and is very good at discerning other people's feelings and situations.
