Thank you for your efforts in translating. I hope you don't take any of the comments about pacing to heart, it is obviously the fault of the artist and yes, even the editor. Even if you totally cut out every scrap of dialogue, it jumps locations with seemingly no rhyme or reason. It is a wonder we can make as much sense as we do of this.
It is sad though, to see what looks like an interesting premise get destroyed by their poor execution.
