the anime doesnt even look to be about ninja, but about samurai. it looks like a samurai anime but with batman characters, how doe that make sense for batman?  

It's just a trailer, we may know the reasoning behind the title when we watch it.

watching the trailer though it makes zero sense, why are batman heroes using swords, when they don't kill? why is the joker now  a samurai sword master, really it looks like a cool samurai anime, but with batman costumes.
