The second OAD Negima series now has a three-minute promo video streaming on the Kodansha website.
Called Mahou Sensei! Negima!: Mou Hitotsu no Sekai (Magical Teacher Negima: A More Unified World *my translation* or Another World *Anime News Network’s), the story was created by Ken Akamatsu and supervised by him personally.
The first of four volumes ships with the 27th tankoubon on Sept. 17.
