 Hiro admires Hatsuharu as a brother figure, even calling him Haru-nii ("big brother Haru"), but also believes that Haru is too nice to everybody for his own good.Hatsuharu has a bad sense of direction, and once becomes lost for three days in another town while looking for Kyo in order to challenge him.He likes to tease Kyo in a deadpan way; Kyo in turn calls him "downright lewd" for saying Momiji should keep wearing the girls' uniform until he gets bigger.
