Huge SPOILERS. Proceed at your own risk.
This comic starts with Brunnhilde's inspiring speech.
Then, Jane tries to fight the Celestial. She struggles but luckily, new Valkyrie joins her. However, her help doesn't prevent Jane from being trapped in Celestial's corpse.
The Jane's visions inside the corpse try to tempt her. But she refuses.
Meanwhile, army of Valkyries that has just arrived try to severe the connection with All-Black. And they succeed.
And so, the souls are freed. Alta and Sentry too (not sure if you're happy with his send-off, @Mørningstar but I hope you won't complain).
To be continued in King in Black #5 (obviously).
This comic, as well as this entire series is great. It has a nice art and thrilling adventure style. The striking moral of this story is very moving. Though, my only nitpick is 'clickbait' cover. I won't complain about not knowing new Valkyrie's name as it will be revealed in Mighty Valkyries.
How about you? What did you think?
