That Kurapika reveal is awesome.
And that completes the Election Arc. I think it was the perfect way for Togashi to go after the Chimera Ant arc. That was a huge and draining arc. It's just great to have this shorter and quick paced arc, with some reappearances of old characters and more comedy. It's great that the arc is in two stories, the healing of Gon and the Chairman election. It never slows down and always keeps you guessing what will happen next. And the way these two stories play into each other is excellent.
The arc also introduces some of my favourite characters, Pariston, Ging and Alluka specifically. Pariston is such a lovable evil mastermind. The way he's more interested in the game rather than winning makes him really interesting. And most of the stuff with Ging is just hilarious. Somehow, he can be both a total douche and a pretty cool guy at the same time. I just love how it throws the readers expectation of him after being hyped for so long. His appearance actually reminds me a bit of the anticlimactic ending of the Three Kings Arc in Yu Yu Hakusho.
Killua is my favourite of the main characters so it's great to get more of him, and he really shines this arc. His relationship with Alluka is really so sweet. A lot of people in these past chapter discussions seem to be very confused over Alluka. I remember the initial fan translated chapters did keep changing calling her either a she or he constantly, and it was different with different chapters or different translators. But with the Viz translations, at least it's pretty straight forward and easy to understand. Killua calls her a she while the rest of the family calls her a he. I think it's pretty clear she's supposed to be a transgirl and that Killua is the only family member that accepts that. It fits perfectly with how Killua is the only one that accepts her overall. If so, it's great to see Togashi having improved in writing these kind of characters.
