After verifying her beliefs regarding Cowl, BMW chose to stay with the Kirakara no Shinto and help them in their efforts to prevent Cowl from coming back to life. She shared all of the knowledge she had with Zhang Xin and Robin Li , and has been assigned semi-permanently through Proper to Wuxing, nominally as an outside advisor to their Magic Testing Division. Her actual location is unknown (and likely changing very regularly), but her partnership and the research she’s done as well as the information she has provided to Wuxing has helped them greatly in the last couple of years as Wuxing has strengthened their position in the Corporate Council and grown their line of magical products and services.
To settle things with the rest of the team, she offered them each a choice: continue to travel with her and the Kirakara no Shinto, or participate in a very thorough debrief session with a Wuxing research team, after which they would receive a lump sum and a new corporate SIN (as their new alias) as well as a ticket to wherever they wanted. Of course, if someone wanted to ride off into the sunset, Wuxing be damned, she wouldn’t stop them, either.
