This is one of my favorite couples... even though we just get subtext in the anime
Well, Hunter x Hunter is definitely a classic, and the whole series is generally amazing in every aspect.
It's really mind-blowing how something with such a innocent style in the beginning can turn into... well, a rather serious and dark scenario.
I love it nonetheless, and being an action oriented weirdo I just love how Killua kicks ass (or picks "important parts" out of some certain nasty people, as in that training at the tower with the convicts 😉 )
About Killua x Gon pairing... well, It's actually almost canon, though I just can't help it but feel very sorry for Killua, as Gon tends to be a hard headed, egoistic and often rather insensitive ass. Poor Killu just needs some love and gentleness, and Gon keeps pushing him too far or treating him almost like his property, aiming only for his own goals. Killua has been shown to have way more human feelings, concern and gentleness, while Gon is the true psycho 🤔
By the way, After a long Hiatus, Togashi Sensei is drawing again, I've seen him recently post some work in progress hints on X as far as chapter 417 (the manga got stuck at 400).
P.S. Kurapika is also very cute. And Hisoka is cannonically a massive, murderous pervert, so keep him away from those boys 🤣
Killugon! Killua is absolutely the best, shame Gon will never know how much Killua really cared about him.
