Instead of being happy you got 70 fragments of him for free and also masked man (so you spent 20k and you got over 20k back before spending a single redemption point) you are complaining because you miss 10. Just wait for next time he appears in events, once every 3-4 months he appears (last time was in a fukurokumaru deal), otherwise open the wallet and roll more or buy an optional kage pack when they put it in one ingot sales. And beware that the average number of fragments with 20k spent was 55-60, so you had also the luck of the devil to get 10-15 more than the average.
