The son of an inventor father makes watches that travel to the future. Apparently, if you push the switch on the watch that is set 7 minutes ahead, then you will travel 7 minutes into the future. The son tries it and calls himself from 8 minutes ago. He tells him that he can travel to the future by using the watch. Takagi wants to add battles to Future Watch. As for Two of Me, he wants to make a fantasy world.
This idea later spawns Ashirogi Muto's second serialized work, Run, Daihatsu Tanto!.
