Hi! As you know, Sasuke [Susano'o] is currently a Super Rare draw in Kage Treasure. His rarity is the reason why the points needed to obtain him is higher.

You can obtain a maximum of 11 free Shuriken daily for doing Daily Missions. You can @lso obtain 1 Shuriken for every 10 Ingots you spend in game.

There will definitely be future events that allows you to obtain Sasuke [Susano'o] fragments. I will send your feedback to the team. It will also help us a lot if you can give us your feedback here.
