Though i already explained this to you in-game, i will explain it here too for the sake of other people too ..

The ninjas where it says "Obtainable from : Tendo Treasures" is not yet confirmed as of this moment. Once they're added in the treasure, it'll be put into the Treasure Details which is the "?" in each treasure that shows the obtainable ninjas from the said treasure .. This info is legit since it is from a reliable source ..

While for the other ninjas that shows that they are obtainable from the Ninja Collection System but you can't find it, it is because the Ninja Collection Scroll System that we have now is not complete, as of now, we only have 4 scrolls while the said feature has 8 or maybe more scrolls .. This scrolls might be implemented or released in our servers in the future ..
