I got my Kushina RHBH at that great plates event. Spent 5k and got 156 frags off her. Recruited her for more or less 2.5K coupons. I just spent my remaining coupons for the power items and got 76 more frags off her after recruiting her. My only goal that time was to get power items, I treat her as a bonus together with that Ay 4th 10 frags reward for hitting 500 points.
