Due to Jack Simmons' performance with the actor Tsuyoshi in the Japanese adult film Cool Guys 3 (クールガイズ 3), Steve Shannon in Hard Heroes, & Brian Maxon in Maximum Maxon 2, Jack Simmons, Steve Shannon, & Brian Maxon technically connect Billy Herrington to the actor Chocoball Mukai.

Because of this, Jack Simmons is credited as being responsible for creating a link between Gachimuchi Pants Wrestling & Manatsu No Yo No Inmu.
