More events have been called to cancel since more threats containing lethal substances have been found. All are concerned with Kuroko’s Basketball and it seems the threats aren’t stopping. Studio You, the company that organizes the Kuroko’s Basketball “Shadow Trickster” events in Japan, announced that three more events have been cancelled due to threats: Shadow Trickster Christmas Special, Shadow Trickster 4 in Tokyo, and Shadow Trickster Nagoya 1.5. The threat letters said:
“If you don’t cancel [the event], there will be many casualties.”
Since last month, more than 20 locations linked to Kuroko’s Basketball creator Tadatoshi Fujimaki, including the Comic Market d?jinshi event, have received threat letters with powdered and liquid substances. A source in the investigation of Kuroko’s Basketball threat letters said there is a high possibility that the liquid sent to Sophia University on October 12 could emit a lethal dose of hydrogen sulfide if vaporised.
