Ep 4. Furi Kiri (Full Swing)

Naota has trouble living up to the standard that his brother set in baseball. Where his brother was the star player, Naota can't even swing the bat. To make things worse, his father and Haruko have been acting weirder than usual lately and he suspects that they have a relationship. It all comes to the climax when a giant outer space bomb heads straight for the town and Naota is the only one capable of saving them...if he can.
