>>8607441 >>8607459Mayu still had to report to the designated birthday room when it was her birthday, as did Hazuki also, and presumably Koguma will too.
It does seem to be schedule dependant though as Saya had her birthday celebrations at the Tokyo Dome theme park before adjourning to Ribera (with SLK, but she could not appear in photographs with them due to kayfabe reasons), and they are running NB7 on Friday so perhaps they might wait until the Saturday for any birthday room celebrations since Hanan, Saya, and Momo will be busy, but they could do something for Koguma either before/after the show.
Maybe Hazuki will treat Koguma to a night on the town the same way Mayu celebrated Hanan's 18th with dinner and drinks before relocating to a hotel for the evening. Ultimately we will just have to wait and see how things pan out for the birthday room and any rendezvous that may take place within those hallowed walls.
Whatever the celebrations, I'm sure we will see some documentation from their SNS posts, and I hope Koguma enjoys whatever may be in store for her on her special day.
