I am not familiar with anime,Jpop,Kpop .....no offense but that style of music doesnt appeal to me.
The closest example I can offer is Kate Bush having an upper midrange,at times hitting even lower treble vs. Stevie Nicks who has a warm sultry midrange vocal style,that rarely hits anything higher.
If your music vocals hit like Kate Bush does on this song,then you want to foucus on upper mids to lower highs
