You are not the only one in that boat my friend, my main shares the most common registered date here 2017-07-24, I own almost every treasure ninja, even managed to get a few of the rares - most notably madara founder and sasuke susano 4 stars, yet I do not have onoki or naruto kurama and I too do not have chiyo 10 puppets, I know she is not in one of the treasures I have drawn from the most, but you would think in over 3 years of consistent playing I would have got the purple draws by now.
