| 2010 ・・ 2019 ・ 2020 ・ 2021 ・・ 2030 |
2020 is the year that last original WACK member Kamiya Saki graduated, causing GANG PARADE to split into two groups, GO TO THE BEDS and PARADISES. Haruna Bad Chiiiin also left the company. At the start of the year, Pour Lui became re-affiliated with WACK temporarily to release her second solo album, before establishing her own company and new group, PIGGS.
In the second half of 2020, auditions for an as-of-yet unnamed new group was held through the internet, as the coronavirus outbreak brought disruptions to many of WACK's releases and activities. As this was happening, MAMESHiBA NO TAiGUN announced their major label debut. In October, CARRY LOOSE disbanded after only a year.
