So, is this a not-so-certain magical index until it’s confirmed?

Earlier today, anime network Animax’s Aniculbu! (“Anime Culture Club”) published a preview for its upcoming October 1 episode. The site was hyping up the installment, which would feature A Certain Magical Index producer Kohei Kawase and editor/producer Kazuma Miki as guests.

The preview (roughly translated) read as follows:

“A Certain Magical Index” Season 3 Confirmed for Broadcast!

A Certain Magical Index enchanted many fans since it the first season started airing in 2008, and later season 2 in 2010. Over six years later, a third season was green-lit for production! Roughly a decade after season 1, what kind of story can we expect?

A Certain Magical Index (Toaru Majutsu no Index) is based on Kazuma Kamachi and illustrator Kiyotaka Haimura’s light novel series of the same name. The show, which premiered in the Fall 2008 broadcast season, was directed by Hiroshi Nishikiori (Azumanga Daioh, Melody of Oblivion) at J.C. Staff. Yuichi Tanaka (My Teen Romantic Comedy SNAFU TOO!, Schoolgirl Strikers Animation Channel) produced character designs for the project, while Masanao Akahoshi (Freezing, Future Card Buddyfight) took charge of series composition.

Funimation holds the license for A Certain Magical Index in North America. Crunchyroll describes the series as:

Kamijo is a student in Academy City, where people use science to develop supernatural abilities. The guy’s got a lot of heart – luckily for a young nun named Index. She’s on the run from a sorcery society that covets the astonishing 103,000 volumes of magical knowledge stored in her memory. When Index stumbles into Kamijo’s life, she find a faithful friend and protector, and while Kamijo’s easily the weakest kid in Academy City, he’s got something else going for him: the Imagine Breaker, an unexplainable power stored in his right hand that negates the powers of others.
