Earlier I was just thinking about the chapter where Hinrigh talked to "Hisoka" because I like the chapter, and in this new one we discover it was Bonolenof all along, he mimicked Hisoka's mannerisms so well that I didn't even suspect it.
Bonolenof is... emmiter isnt he? Sure there is a lot of transmutation there, but when he used that Jupiter ability, the fact he made an outside nen construct detached from himself shows more of a focus on the emissive type, but as he clearly is a strong nen user, he can do the other types well.
Edit: Just went to look at his wiki page, there he is categorized as a conjurer, which makes sense too, still a strong user with how he must make use of the other categories.
