Toaru Kaki no Campaign

Toaru Kaki no Campaign (とある夏期の限定企画(キャンペーン)), translated as "A Certain Summer Campaign" was a large promotional event that occurred near the end of August 2013, coinciding with several marketing events for the Toaru Majutsu no Index franchise.

Toaru Sakuhin no Convention
Toaru Sakuhin no Convention (とある作品の大総選挙（コンベンション）) was a character poll that was part of the event, featuring nearly every character in the franchise. Normally, the polls would have been topped by Misaka Mikoto due to her sheer popularity, but upon its opening, 2channel Vippers began influencing the polls, and have made automatic voting programs, voting for things such as Gekota, to even Hino Jinsaku. Jinsaku later becomes the first ranked character upon the 103,000 votes, and would get a Haimura-illustrated message card with messages from Kamachi and the other comic creators.

The poll however, will continue to go on until 10th of October, and the first rank at that time would get a "project".
