there was an event this 2020 if i can still remember 1 frag was only 90 coupons.. I think that was between january or february.. if I am not mistaken she was in what they call now amu*t so so so.. can't remember so well but I bought her with just 8900 coupons for 80 frags. In naruto ramen 1 frag is 140 and I will not 100% agree that the best event to get kushina is great plates. Sometimes you can't get the 2 frags for 20 draws. Other than that, the other rewards in great plates are great. that's only my opinion.
