PLOT
Sousuke Mita's son, Tsuruo, got married in his mid-30s. Sousuke thought he could live happily ever after, but his wife, Hiroe, makes a sly request that he leave him in a nursing home, since one of the conditions of their marriage was that he not live with his parents. Sousuke, who was tired of staying at home, met two old men at the park. Their hobby was to rape married women who made fun of the elderly, armed with balaclavas and goggles, as the silver corps "Gateball Gators"! When Sousuke learns of this, he plans to punish Yue. What exactly is Sousuke's plan...
