Chapter 025: Accelerator destroys both Qiong Qi and Taotie.
Chapter 026-31: There was some flashback to prior the start of the arc, where we see Hishigata and Estelle past and how are they tied to each other and the reason why she want to stop him no matter what it takes, as she learn that there are conquces to what they have done and she is trying her best to make it up by doing what it is required to stop him...
PS. Chapter 31 belong to the next volume not this volume, but due to the fact I can't really remember what happened, I posted as a whole as it must be have been not important otherwise I will be able to recall what happen...
