It does look like she will get sidelined for at least a dozen chapters more, because I don't think the rescue can be done in just a few lmao. Unless powered up Win just comes to their base, breaks in, takes her and leaves lol.
well it could happen since that is literally what happen with Mashiro saving Gloria lol, maybe Win will get capture and it's the end of series, a sequel with a new protagonist once again and they will have flashback what happen to Win after her capture..
