2- Fire Starter

Naota tries to get his life back to normal, but that's easier said than done when Haruko and a TV-headed robot are living with him! Even worse, he's growing another horn!! Meanwhile, a string of fires have been occurring across town. Not coincidentally, Mamimi has become obsessed with the game "Fire Starter", as well as Naota's robot manservant, whom she calls Canti. What connection is there to the recent fires and the one that burned down the old elementary school years ago? And, why does Mamimi call her new pet, a little black kitten, "Ta-Kun", the same name she calls Naota?
