0/6

0/6

At first glance Moolchi is just another shy, unassuming boy whose greatest talents are running away from bullies and binging on vitamin supplements. Then one day, Moolchi's absentee father sends him a most unusual gift--a stunningly-proportioned automaton. She calls herself "Six" and mumbles about having a "prime directive." This strange and exquisite creature quickly turns the boy's life upside-down, violently disposing of high school hooligans and anybody else who gets in his or her way. The word "oblivious" barely does him justice as Moolchi remains blissfully unaware of his father's dangerous double-life, or the cute hall monitor who harbors a crush on him, or the intentions of this mysterious femme fatale who insists on bathing with him. Meanwhile, ominous storm clouds gather on the horizon, and one lingering question looms above the others "who is this so-called "Zero" that everybody is looking for?
