Hi there,

Thankyou for your suggestion... Although many ninjas are added to the shops over time its extremely unlikely for them to be added within one month and for some of them to be added at all... The purpose of events and gaining coupons in the game is for f2p to piece together ninjas slowly if they chose to as its an individual chose to go for a ninja... I appreciate that everyone would like to achieve all available ninjas ASAP but that's just not quite feasible... =)
