I don’t think we’re going to see Tserri for 40 days and 40 nights or until 9 days left in the contest.We just got three chapters from his pov he’s an inverted Christ so these are his three days alive whereas he ‘dies’ and is forgotten at the end we even see him die in the last chapter.

I think it would be an amazing Christ parallel aswell as serving to give meaning to 9 being one of his lucky numbers 

The number 9 can also symbolise divine completion and the end of a cycle in Christian faiths.The number nine comes up in the fulfilment of God’s plans aswell as Jesus dying on the cross at the ninth hour of the day.

Tseridnich going down to tier two is the same as Jesus wandering into the Judaean desert and starving himself I think Tserri is going to detach himself from his luxury and even food/water/sleep in this time persisting off of just aura

I think he’s going to reach his Zetsu target,Aswell as practicing Ten,Ren and Gyo (what he knows) and luckily for him (he constantly gets lucky) stumble upon Ken,Ko and Ryu from this practice 

I also think a devil is going to start tempting and dissuading him a little bit into this exile in the form of Benjamin I think again Tserri gets lucky and Benjamin’s nen beast not only gets first dibs but picks him due to Tserri best representating what Kakin is 

Now I don’t think we get nothing on Tserri I think we’re going to get mentions of him here or there but in the form of the ‘masked man’ terrorising tier 2 and the Xi Yu family which is literally Tserri getting practical experience against nen users 

I also think he’s going to remain in the masked get up for the entire 40 days with him taking it off symbolising his completion 

As for what happens on tier one and two during the forty days I think shit is going to very soon hit the fan.As soon as Benjamin dies and martial law ends with him likely having murdered or caused the deaths of every single higher ranked prince but ultimately failed the place is going to erupt I think the plots of the Heil Ly/Mafia factions,Hisoka vs the troupe,The lower levels rioting and Beyond’s escape are all going to happen all at the same time during the 40 days like a really big and long palace invasion arc just back to back to back all at once and Tserri is going to be forgotten and then when things start dying down and the coast is clear he’ll luckily be an extremely formidable nen user/one man army aswell as the clear favourite to win the succession war when he returns to tier one but I also think his ego returns which is ultimately what gets him killed 

Where I think Tserri and the overall arc is going to go from here
