...but I don't think so, "KEI"(firefly) is a common kanji used in name. (may
for girl mostly)
an example: "KEIko yukimura"(Yuusuke Urameshi's girl friend) in
"Yuu-Yuu-Hakusho". but, she is a girl, do you think they are similer?
so, I don't think it has any deeper reason.
( BTW, in chinese or japanese, 'firefly' is the only meaning of
"KEI(kanji)"/"YING(chinese)" )
