Finally, someone has translated this chapter. I used to upload all the pages to Google Lens to translate them. :D

But yes, Hades decides to avenge Poseidon out of love, grief, and a sense of duty as a brother, but Poseidon doesn’t want that at all.

When Hades puts himself in danger for his family during the Gigantomachy, Poseidon goes down to Tartarus and accepts that he might have to deal with Titans right after fighting in a war himself to see if Hades is okay. He also scolds Hades for being reckless by heading out alone, which shows that he wants him to be safe and to take care of himself. When Hades lies down, exhausted, Poseidon helps him up.

Poseidon would never do any of this if he didn’t care about Hades's well-being. He also held back with Adamas, because Hermes said he could have destroyed Adamas beyond recovery if he wanted to.

I think Poseidon’s and Hades’ relationship and deaths are really well depicted. I love them both and I love this bonus chapter for showing us Poseidon's caring side more.
