黒子のバスケ
In 2012, anonymous threats made against circles creating works related to "Kuroko's Basketball" led Comiket to prohibit the sale of all "Kuroko's Basketball"-related items at Comiket 85 (see Kuroko's Basketball § Controversies). Organizers refunded the registration fees for the roughly 900 circles producing "Kuroko's Basketball" items, resulting in a loss for Comiket of roughly ¥10 million. In 2015, ComiketPC organized a special event specifically focused on doujinshi related to the series. Affectionately nicknamed "Kuroket", the event hosted approximately 2,400 circles producing "Kuroko's Basketball" items.
