>>5968543>recently airedThe last episode of the rerun go around was in april. Could be considered recent.
But if anyone wants to know why the prices are nuts and thinks it was kids and current "flavor of the month" the stats don't tell the same story.
After the initial boost in ratings Toonami had after reintroduction there was a slump in that caused them to lose their first few spots and be pushed farther back into the graveyard time slots (post midnight). To stay afloat this they decided to bring in KLK to replace the AoT reruns in Feb 15.
The initial run consistently pulled over a million viewers a week in the 12:30-1:00 AM slot Trailing DBZ Kai at midnight by 100-300k, and outperforming Naruto, InuYasha, Gurren Lagann, and One piece (in later slots up to 2:30 through 2015). For the rerun release it was moved to anchor the block at 3 am where it still brought between 700k and 540k viewers a week up until it ended.
Or if you want outside statistics from Nielsen KLK's initial run was the 11th most watched Saturday night original programming in 2015 with an average of 1.18 million viewers (for reference beating out SAO 2 by 100k). It was one of the highest rated by A18-49 (which specifically works to figure out adult viewership.) through summer 2015 with a solid 60% with dips to 50 beating out everything from the usual adult swim block which hovered around 40% (Again using SAO 2 as reference as a big release at the same time which sat at 40 occasionally hitting 50) to Friends reruns at 50. They classify a major hit among summer adult viewers at 75%
And I only know this because I was forced to take a communications class and forced to do a project in that class so I kept tabs on how Toonami was doing.
TLDR: The merch probably sells high now because the majority of the show's normal TV audience in the US are working/collage age and up so they (theoretically) have expendable incomes. Wait for them to get bored or move on and things should settle.
