“In 2013’s first issue of Shueisha‘s Weekly Shonen Jump magazine which ships on Monday, Kuroko’s Basketball creator Tadatoshi Fujimaki wrote in his author’s note that he will keep working on the manga without a break “no matter what.” The magazine is announcing that the Kuroko’s Basketball events at next month’s Jump Festa have been cancelled. A string of threat letters with powdered and liquid substances have been sent to locations tied to the manga and its creator since last month, and they have resulted in cancelled events into next year.”

I predict two possible repercussions as a result of this statement: said terrorist will step up his efforts in either attempting to kill Fujimaki or create as much chaos as possible. Earlier events had shown that he isn’t all talk and no game after all. This means that JUMP and other companies either have to cancel featuring Kuroko no Basuke in future anime/manga related-events or step up security which means a depreciation of profit and investment for Kuroko no Basuke. Whether this means a second season is going to be considered is questionable. Still, while this act of terrorism may have killed off weaker anime with a smaller fan-base, Kuroko no Basuke has proven to JUMP that it has a huge fan (almost cult) following which if anything, should hopefully raise the chances for a second season if anything. We can only hope.
