Abstract
We show that axinos, which are dominantly generated by the decay of the next-to-lightest supersymmetric particles produced from the leptonic -ball (-ball), become warm dark matter suitable for the solution of the missing satellite problem and the cusp problem. In addition, coincidence is naturally explained in this scenario.
