The whole series started because of one guy (the second son, Haru) failed to kill the enemy cuz he got no guts yet calling himself a ninja. The enemy then almost kill his brother (first son, Gaku) but suddenly changed of heart and saved him instead, turning him into a mole within the whole ninja for a scroll containing the family tree of ninja.. despite being too useless to save his own family or to finish up the enemy, the second son is soooo busy playing with his b_lls, trying to be hero with the reporter lady he met (cuz he gave his virginity to the lady), and abandoning his family in the very important time, to save her from the agency that aimed to protect his family (what a drama). Subsequently, the whole family roll out to save the first son from the enemy.. The only strong one and deserve watching is the father of the ninja family. Really waste of time to watch it. Just read this review and it saved almost 8hours of your life.
