This was probably one of the most important chapters we got in a while.
We pretty much know at this point SK=King Gaiseric. All thats left is just to explicitly state it in a chapter.
I am pretty sure this was where SK/King Gaiseric died. Guts says "That right now...was for sure...the end-" and looks at SK. Even Hanarr himself says "A blood memory that's seeped into the armor. What caused it's previous owner's life to be consumed by the Berserker."
I dont think the monsters that appear out of the tentacles are apostles. Miura has previously shown significant effort to make the apostles look distinct.
The highlight of the chapter was definitely the "old" god hand. Theres a lot of possibilities here. The most probable one is that this was the birth of Void as a god hand member. The way he stands before all the other members mirrors how Femto stood before all the other members when he was born. SK's condition also seems to mirror Guts' condition back then (Gedfring says "The memory seems to resonate with him").
If god hand members are born every 216 years, then maybe SK managed to kill 4 of them and Void "rebuilt" the god hand with Slan, Conrad, Ubik, etc. Or one by one, they just "retired" (for lack of a better word).
Now I dont think that lady is Slan. She bears more of a resemblance to Danann. That would also explain SK's connection to elves. Maybe she was just was Casca was to Guts.
But that raises the question of how Slan knew SK and even addressed him as "Your majesty".
I have a feeling the next chapter would be even more monumental than this one. This one raised a lot of questions but also answered some. Very excited for the next one.
Also, condolences for Miura's friend. The "so lonely" part hurt me a little...
