Hello!

The possibility is there but I won't gonna say it will happen any time soon. They are Tsukuyomi or Ingot Exclusive Ninjas as of now and the only players that can get them are the ones who spend a fortune in the game and if they will be on Fukurokumaru's Deal soon, that might cause an uproar amongst the players who spent bigtime. My assumption, it will never be for the meantime and when I say meantime, it is more than half a year or so. Thank you.
