Season 2 · Past the hinting

The sequel opens on the far side of Season 1's biggest unspoken question, with real stakes on the table. New director, new animation studio built from the previous one's staff, same returning character designer and scriptwriter. Sunday afternoons in Japan from October 4.
What everyone's talking about
The premiere conversation, condensed. Paraphrased from public chatter.
“New studio, same team. The people who made it look like that came over, so the look should hold.”
“Nobody agrees on the length. One cour, two, a split, and every guess about how far it gets is somebody's guess.”
“I parked it after the renewal so I could watch the whole thing in one run when the sequel got close.”
