That depends on the level of Starlight Breaker.... given this appears to be A's Nanoha, just friends for life. If it were original Nanoha it would be life partner, and if it were StrikerS it would be adopted daughter. The real question is why did Nanoha from A's get sent over when Archer ended up in the original series?
Haven't seen Yakuza Princess Kitasan in a while. These days it's usually Yakuza Consigliere Drejour.
I mean... Journey's MO is very yakuza-like... not to mention her Anego is often called a yakuza boss by keiba fans thanks to how he's functionally the patriarch of the StayGo clan.
