BB's biggest mistake wasn't creating 5 Alter Egos, it was creating alter ego with the specific ability to absorb her power. Kazura's entire existence just make BB come off as a complete morron.
You know, the Kazuradrop twist is neat on paper, but in execution, it take one of CCC's problems and makes it 100 times worse, because if you thought Sakura didn't have enough screen time in the original, here she literally never actually talked to Hakuno.
The play was really cute. I loved how it's basically a parallel to Kokosaki and Mashiro's relationship. I hope someone will pick this up soon. The raws are at 154 chapters so far....
