Senpai? Is B is her senior or something? It seems that Kyouko-chan knows B already, could it be that B is her senior from college?
B is smiling and staring at Kyouko-chan while crossing her arms, and when I look at Kyouko-chan's expression, her surprised expression has changed into hatred and anger. Now I really have no idea what's going on between these two so I'm just going to watch and listen from the side.
"Horii-san, why are you betraying us?!"
So B's name is Horii and it seems that Horii was her senior from the unit that the emperor himself made. By the looks of it, Horii betrayed the organization and now is working with the people that she swore to get rid of. This is really interesting and surprising at the same time, so I'm just going to stay quiet and pretend that I'm not in the room.
Horii is chuckling while walking toward Kyouko-chan.
"Do you think I betrayed his emperor, Yanagisawa? It seems they didn't tell you a thing about what happened to me, weren't they?"
