Started in 2001 as the evil mad brand of Cyc Co., Ltd. then followed the movement when B-Eye Communications took over the business. Slowly died after a talents leak. After Sayoko, the brand was transferred to Ranba Amuse. It remained inactive (excluding the re-editions) for a long period of time until the brand was revived in 2016 with Extravaganza ~Mushigurui Hen~.
