WACK (better known for being the home of BiSH) announced that their trainee unit WAgg is going to disband on October 18, that day they are going to hold their final concert "WAgg's wonderful future", what is going to happen with the members is going to be announced at a future date
to give a resume, for these past 5 years WACK has been rising in the hierarchy of Japanese entertainment companies, to fuel that growth they were going to require a constant influx of people joining the company thus in 2018 WAgg was created to hold their new talent while they found a place for them in their expanding line up of groups
the thing is that WACK's success has made it pretty easy for them to find countless amounts of people willing to join the company, for example just these past 12 months WACK held 6 large auditions and every time a new audition was announced people from other idol groups or even from big companies keep submitting applications to enter the auditions, the result is that WAgg has been getting ignored in favor of newer, bigger talent
as a matter of fact right now there are only 4 promoted WAgg members active in the main groups so this was expected and honestly it may be for the best, there are many talented people in the group that got stuck as trainees for these past 4 years, definitely a waste of their time, hopefully we get to see more of them in the future
something surprising is that the WAgg trainees not only get money from their activities (which is expected) but also get a salary, sick leave, etc even the biggest idol companies rarely do that so no wonder everyone wants to join WACK
