XSEED has been sharing various facts about their company and games as a way to celebrate their 15th anniversary. The above, believe it or not, is one of the tidbits that XSEED shared.
It's no secret that the Senran Kagura franchise focuses very heavily on its fan-service component. Anyone who's seen even a few moments of footage from any installment can pick up on that quickly. Still, there was a point in time where XSEED thought they really had to drive that selling point home, which is why they briefing considered calling the original game 'Ninjugs' for its localization. I think we can all agree that skipping over that idea was the right way to go.
