Girls’ Frontline is going to have Operation Cube coming up and has an on-going EXP boost event in preparations for it. Operation Cube will be all night battles. T-Dolls will need to be at least level 70 to pass all four missions.
I’m super excited and I at least have one echelon unit ready for it. Also, I’ll try to get a second echelon ready during the current EXP boost event.
Another note is it seems a new batch of T-Dolls will be coming besides the event exclusive OTs-14. One of them in the shadow is G11.
