I think it's one of the more tougher manga to predict, simply because it seems like Guts is against an impossible task. He does still have his Behelit, and Miura has all but hit us over the head with a sledgehammer regarding him losing his humanity, to the point where it's a bit too obvious. Maybe Griffith will surprise us. I've felt more and more that maybe the thing Guts will have to sacrifice for the greater good is his vengeance. And maybe Casca will be the turning point for that.
I don't think this series will end without Griffith x guts fight on a different scale at least once..too many stuff like how berserker armor is raring to let all out and how griffith is supposedly planning to invade elfhelm since it's based around a spirit tree which he has destroyed many over the land of midland for the "light tree" to spread out...
But..I guess he could come over his vengeance when he as i think if griffith is part of their child and they team up against the other 4 Godhands...i wouldn't mind that as well..
Or maybe Guts' Behelit isn't even his in the first place, which opens a whole bunch of other possibilities...
Didn't he pick up that behelit from the father apostle who tried saving his daughter in Black swordsmen arc.(stolen by the old doctor).it's technically isn't his but he can use it though if he has a sacrifice and put some blood on it right?..
Who do u think Guts will sacrifice if he needed to use behelit?..it has to be someone close to him right?..(i know it's a stupid question to ask but still)
