Suikoden II
The Leisure Attack is when the Family Attack fail, resulting in this attack instead.
In it, Nanami start slacking off by cheering, eating, drinking, reading manga and singing as Riou keeps on attacking. When this happens, Nanami will not be unbalanced and she will recover some HP after the attack, however the damage to the opponent will lessen as well.
If Nanami is equipped with the Leisure Set, the rate of Nanami performing the Leisure Attack will be raised.
