The demons turn Hanappe's home into a meeting ground for their demonic friends and grant Hanappe the power of the Hanappe Bazooka. Now his index finger is capable of both a deadly blast and the ability to drive women in a lustful frenzy, but Hanappe isn't very good at controlling it and winds up in serious trouble.
