Here's a summary of the episode: We see the flying apostles attacking Ganishka, passing above the group and getting fried as if they were meaningless. They all get killed seemingly effortlessly by a huge lightning attack that hits everything, the burning head of one of them falling right next to the group. Some thunder barely misses Serpico so Guts tells him to get away (sensing that the situation's turning bad), Serpico is hesitating but eventually does. After that Guts thinks to himself that he'll end up as a piece of charred meat if he sticks around too long. Then Zodd arrives. He lands on a roof near the group (and Farnese recognises him from Albion, like Casca apparently) and watches Ganishka...
And suddenly propulses himself at high speed towards him! Ganishka casts lightning at him and hits him directly, but Zodd takes the hit without slowing down and flies right through him! That's inefficient however and the fog figure instantly reforms itself, with Daiba commenting. That doesn't stop Zodd though (although it visibly hurts him) and he attacks again while taking Ganishka's lightning, finally rushing him together with a bunch of other apostles. Ganishka then morphs into a huge cloud with the apostles inside and electrocutes them once again, killing them all (save for Zodd obviously) and sending a burning Zodd flying and crashing on Guts (and into the sea).
Next episode will be released on July 28.
