Reading Haruka and Fumika's blogs reacting to Akari's sudden graduation, it felt like they were close but, then again, we have no real way of knowing the truth, which includes whether they actually wrote it or not.
This is the second Party Rockets member that left for a bigger (in the case of GALETTe, that's debatable) group. Add to it, the 3 members from DLH leaving to concentrate on callme at the end of the 5th anniversary tour and I wonder if everything is okay with StepOne. It was nice to see Shirato Kana (DLH) performing with them at TIF though.
Once they announced Fumika and Haruka were moving to new management while Akari was staying with the same ppl who manage GALETTe, the possibility seemed more likely.
GALETTe has planned a year-end one-man at Diver City so I guess they're at least at the same level as lyrical school?
