Natsuhiko is a seemingly shallow individual, although he is not unfriendly. His motives are rather dubious, and it appears that he works with Tsukasa and Sakura simply because he has a crush on Sakura. He was willing to trick Nene and put her in potential danger but doesn't seem to have any ill will towards her. He is rather reckless and perhaps not too bright. He is loyal, or perhaps obsessive, to a fault, since he continues to have a crush on and pursue Sakura ⁠— despite her outwardly cold demeanor.
