I wonder how they are going to handle this arc. I doubt many anime-onlies are going to remember Nat and Shiggy explaining the birthday death disease and Kiyui getting taken to the pharmacy ship in season 1, which is basically what kicks off the surface side story.

>How are you somewhere 1
Shows Riko's dog which highlights the mystery of Reg's name and introduces Mio. Would be great to see it animated but is ultimately inconsequential to this arc, until Reg meets his sister.

>How are you somewhere 2
Already partially adapted randomly in season 1, excluding the part about the praying skeletons. Leads directly into Juiro's visit to Ozen.

>How are you somewhere 3
Furthers the birthday death disease phenomenon. Ties it together with the praying skeletons and the 2000 year cycle. Leads into Ozen and Jiuro's visit to the Orth Slums.

>Museum Twins Extras
Acts as a red herring in the Sherumenae mystery. Ultimately proved to be inconsequential.

>How are you somewhere 4
Am I blind or does how are you somewhere 4 not exist? Neither of Faputa's extras have a chapter title and neither does Ozen's trip to the slums.

>Volumes 11-14 with the chapter 63 flashback mixed in with all of this

>Ozen's Trip to the Slums
Furthers this storyline, namedrops "The Breath" in relation to the 2000 year cycle. Introduces no-fap lady (Nugget version).

>How are you somewhere 5
Provides a reference point in time for the meeting in the plummet pub (day before chapter 1) and the joint delve reaching the 2nd layer cave (14 days later). Also cryptic star compass lore.

>How are you somewhere 6
Tepaste & Cravali lore, no-fap woman (not yet nugged version) shown likely as a way for readers to draw connections between her nuggified version and the nuggies.

Im confident they will pull it off, but I wonder how especially in regards to the S1 blunder.
