This was such a great chapter, always been one of my faves. Sanakan really shows how much of a boss she is by taking out those two silicon life creatures, and you know it's Sanakan because she absored that launcher attack like she's been shown to do earlier in the story. Since she is an representative of the Administration, who was always helping Killy and Cibo from the beginning, I'm guessing she took away her safeguard status and became a higher position and now wants what the Admin's wanted which is to stop the continued creation of the city? Who knows, but I'm looking forward to more theory crafting lol
Also super sad seeing the builder just shut down like that. He really had the best intentions to protect Cibo, but he did a good job relaying the video of what happened to Killy.
