I was wondering what was done in the 2.0 update to make this mission so hard. I tried when I first got it and couldn't beat it 3*. so, i recently came back but it's even harder. I die in one round and it's terrible. I cannot upgrade my ninjas without the shimenawa from that mission, so it's like I might as well just quit playing. I'm not sure the point of making it over ten levels higher than the plot's level, but I am not a fan.
