Didn't know about the game or this title before watching the first ep...took me a few minutes to realize these guys are actually reincarnations of the swords. The Japanese sure like to personify inanimate objects don't they?
But if these guys are swords...then what of the swords that they are wielding now? Swords wielding swords...
This looks like a fun series to watch but I'm really looking forward to Ufotable's version - that looks like it will be really good!
