>Next chapter: montage of them climbing the middle four levels and discussing the dungeon crawl, ends either as they start cracking the final door on the sixth floor, or when Arc Mage realizes she can’t finish the final key in time before they get overran

>Chapter after that: prolonged siege on the final door, ends either as Goblin Slayer pulls out the Gate scroll or after Arc Mage opens the door after the Goblins get flushed away

>Chapter after that: GS and Arc Mage go through the door, climb the final set of stairs to the roof, she gives farewells and vanishes, GS makes walk back to town, drinks an apple cider in the tavern in remembrance

>Chapter after that: Epilogue chapter of GS and Cow Girl packing up the stuff in Arc Mage’s cottage, going home, and unwinding together in anticipate for the next volume (if it ever comes)

I think we got 3-4 chapters left.Chapters 3-4 could be compressed into one with if the farewell scenes are cut down, but Goblin Slayer has used some very decompressed storytelling so far so I don’t anticipate that. The remaining fighting scenes have to be at least a couple chapters though, it’d be cheating us if they weren’t.
