With this week's novel sales data coming out from Oricon, Mondaiji-tachi got a pretty good boost in sales after the first anime episode. How does it compare to some earlier LN adaptations? Someone on 2ch compiled a list of sales after only the first episode aired of recent LN adaptations and I calculated the percent increase we can attribute to the first episode. This list is sorted in ascending sales post episode 1.

Durarara!! definitely takes the cake for increased sales (and rode it to over 100,000 for the first volume, but surprisingly Mondaiji-tachi is second, even besting the amazing increases for BakaTest and Hyouka. Given that it's a Kadokawa title, meaning high prices and likely to get a quick BD-Box release in the minds of fans, BD/DVD sales might not be high. This could be the way fans support the series. LN v8 will also come with an OVA this July so that'll also be interesting to track.
