Hisoka X Chrollo

Yeah, but as it goes with the contracts there must be something he gives up as a sacrifice. And we don't know what he gave up if he went that route.

The way he did it fits in line with the way Sun and Moon retained functionality after the Elder's death.And in Hisoka's case, it only worked due to the nature of his nen.

My point of reference to this is how Pitou's Nen reactivated after her death, probably as a failsafe she set up just in case

Hisoka's was probably something like "yo imma bout to die but in return do all this cool shit to make me come back"

Yeah, that's pretty much how it went.

Moments before the boom, he enshrouded his heart and lungs with the rubber nen and gave instructions or "conditions" to simulate CPR to retain oxygen and blood flow after some time.

>togashi brings back the concept of nen getting stronger after death in CA and DC
Do you think he's been using it in interesting ways?

CA and DC?

While I do think there are some overexaggeration in the theory, the fight does have some clue here and there that something happened behind the scene that was never explained at face value.

What "clues"? The fight is already explained. There's nothing more to it, Chrollo won and Hisoka lost in a fair 1v1 match.

I always thought nen after death would act on its own accord based on user's strong feelings and there was no need for a user to specifically command his nen to act. It's unpredictable that way.

Now that Hisoka has shown to have explicit command over his nen after death, there's no reason why any nen user shouldn't be able to invoke nen after death use it to their advantage. Togashi fucked up

Did this fight confirm that Silva and Zeno would also fuck up Hisoka?

Well, very few people have nen that can fix lethal wounds, even after death. Hisoka is pretty much the only one because of his rubber nen. But before that, even Pitou's nen acted up after her death against Gon.
