tbh I don't see Guts going berserk because if he did, in his rampage he'd damage the ship and it would sink and everyone would drown which would be the shittiest way the manga can end. Unless Farnese brings him back before he does too much damage? But there is a lag, and without Schierke to guide her she has no idea what to do, so unlikely. He's probably still catatonic and is just letting himself be lead by the Kushan because what's the point anymore. Or plot twist, he actually knows Kushan and had a nice chat and knows they're tight with Rickert.
i still have alot of questions about the setting. do they live in like a survivor city or some shit? if so where is everyone? so far, we've only probably seen about a just dozen people in total. are they a part of the government? if not, where are is the government? how did they manage to get such advanced gear? and why are they super cautious against zombies. two "professional" zombie killers (her dad and uncle) were literally hiding from a single zombie in the first chapter and had to kill it with a drone
im seeing a lot of support actually that gojo shouldn't have died, not slander. the gojo fanbase is strong and for him to go out with some bs ending dialogue like this is insane bc he was working sukuna all fight.
