I cannot agree with your theory for two reasons: 1 - It seems to me that it would be a bad option for Otabe to decide to stay in a group that (according to your text - my japanese it's not good enough to have caught that) is "bad" just waiting for a opportunity to take "Solt" down. Basically she would be doing the "devil's" work in the meantime while waiting for that chance. 2 - And more relevant: In my opinion, there is no way management will present Paruru in a bad light. Paruru will not loose to Sakura just like Yuko never lost to Maeda. At most, there will be a draw between the two. Even though, I still believe Paruru is the management favorite, and as such there is a high possibility that she will become the stronger in the end. That aside, an interesting thing that I notice: "Solt" is actually a mix of Sado and Yuko. She uses similar shoes to Sado, plays with a similar toy and is, basically a "S". Spoiler One question: Did anybody understood what the gesture of opening her mouth meant for "Solt" after the scene where she defeated her opponents in the hallway? Was she sleepy? Bored?
