^ unironically tho. i would've loved to have seen hisoka in the chimera ant arc rather than greed island or chairman arcs. it would've been interesting to see his reaction to the royal guard and seeing gon unleash his potential under the circumstances that he did. chrollo is right there with him, it's a shame we probably won't see how their rivalry ends.
mureum was the most developed which is pretty impressive considering he was only around for a single arc. not that character development is the be all end all for what makes or break a character. in fact, i generally prefer yu yu hakusho's characters even if they're written more simply.
