Where we discover that Sumiji has a long experience in abducting high school girls in his van. And that being Yuki was already suffering back then.
It almost makes me wish Yuki had remained the main character in Act-age, but then we wouldn't have had the blessing on the world that is Kei, so it's a tough dilemma.
The writing was already on point, but damn has Usazaki's art improved in the past two years… The panel layout is almost stiffening, although that might also be the writer's fault.
