It was last seen on Mission General Mobilization for 105 points per Pack .. I was able to get 10 packs that time since i really want to get Kakuzu, and pair him with Angel Konan .. Now i redeemed only 3 kakuzu frags and the excess points went to power-up items ..

It is the pack that is bugged after the maintenance and only shows "?" image with description "null", then emergency maintenance takes place for another couple of minutes and got fixed ..
