So, Nisshin's thing there is almost a 1:1 quote from the movie (replacing Hiroshima with Shipgirl), and mysteriously, googling it for meaning gives two things - one saying that they've never lost/been at a disadvantage to other yakuza groups in a fight, and another saying that it means that they won't fall behind other yakuza groups (read: the Akashi-gumi).
I've never seen the film, so I have no idea how it was translated there.
but we're not ones to be nipping at people's coattails.
