Mini sticks with Fatso everywhere, and although initially vexed by Mini, Fatso discovers the reason behind her depression. Mini cannot forget her former boyfriend, Kurokawa, who is now a world-famous pianist. Ten years ago, the two had pledged to meet at the foot of Yokohama Marine Tower on the night of their break-up. Mini is fearful of meeting Kurokawa in her present size. Touched by her story and her sweet nature, Fatso promises to whip her back into shape.

After trying desperate means of losing weight (such as swallowing tapeworms and exercising to Dance Dance Revolution), Mini finally sheds pounds. But Fatso finds his funds running low. To earn enough to finance Mini's weight-loss programs, he opens a boxing gig on the streets allowing on-lookers to punch him to vent their pent-up frustrations. He next enrolls Mini on an expensive weight-loss program, which proves to be very successful. Mini regains her former slim and pretty look.
