According to Weekly Shonen Jump,
the second season of kuroko no basket was announced.The series of threatening letter cases aimed at Kuroko no Basket has not
been settled yet. Although the Tokyo Metropolitan Police has been
investigating the case since last October, it has come to a standstill
because the culprit apparently has no personal relationship to the
author. The threatening letters have been found to be sent to more than
50 places within Tokyo. According to the police, the solution sent to
Sophia University along with the letter contained more than the lethal
dose of hydrogen sulfide.
