Ken Akamatsu
From the "Negi no Ochakai" event that was held in May 2008, Ken Akamatsu mentioned that if pre-orders for the first of the OADs exceed 50,000 the staff would consider a film adaptation, and if it exceeded 100,000 views, the staff would consider a third animated series. The counter on the official website reached 82,581 before the first OAD was released. The total sales of three volumes was 245,000 copies.
