I'm for the individual page. Nanika has a different background from Alluka, different personality and abilities as well as an autonomous identity. "All" they share is Alluka's body.

As for the pronouns, I am fairly sure Nanika regards herself as being female. She asks Killua if she had been a "good girl" after healing Tsubone. So, while she possibly does not have a sex, she has a gender.

I think it's Viz that uses "Bloster". I take it back, then, Nanika is fine.
