You should get sage naruto because he is a really good ninja at around 4-5k coupons if youre lucky. Don't get Minato because he is not good IMO. You can see the ninjas that daily special will have throughout the week in the event thread. If you are new to this game, DO NOT PULL FROM ANY TREASURE EXCEPT FIVE KAGE TREASURE AND spend all your coupons on Lucky Board and buy medium refines
