A couple of days ago, Nami had suddenly been pulled out of any work she was scheduled for; Stages, promo work, and anything that couldn't be done by anyone but her, was postponed. The only reason given from the management, was "Matsuto-san needed a short break. She'll be back before you know it". Then, her name alongside an announcement of her return had been posted, underneath the words "Succession Debut!" with a date and time for the concert.
A few more days had passed, and despite the short notice, fans had made their way to the concert hall, and it was quite the respectable number that had made it there. The lights in the hall were slightly dimmed, and the words "Matsuto Nami Succession Debut! Nami no Upgrade" were written on the large screen behind the stage.
