Yeah,
He looks quite happy go lucky. A little too cheery and innocent.
Kakashi can be cheery but you know there is nothing innocent about him, more like blatant disregard.
Whereas this Chichiri character appears a bit like Miroko from Inuyasha (not in looks but in the wide-eyed innocence that Miroko puts on at times)
Even his pissed off badass pic doesnt come close to kakashi's. Then again I havent seen the fushigi yugi anime so I guess I can't say much.
