Jack The Rabbit

Being the sole survivor of his family, Hayato sets out on a path of vengeance to bring down the Fukuda family who ordered a hit on his dad. He creates a persona named Jack, born from his pain and hatred, the perfect assassin to carry his vendetta.

The president of the Fukuda Inc. in New York starts investigating Jack, to finish the job from 20 years ago. Vengeance is a powerful tool and a double-edged sword, hooked on the company's underground drugs, Jack's life is shortened but he plans to finish his mission before meeting his end.

Unfortunately, Hayato's third persona, Enji, falls in love with one of Hizashi Fukuda's daughter and Jack's objective slowly becomes compromised. Enji started dating June but Jack keeps popping up once in a while making her more suspicious of him.

Finally a confrontation between June, the Fukuda's assassin and Jack, the rabbit occurs and both left badly wounded. June finds out Enji was actually Jack after seeing the scar she gave him on the lower left side of his stomach... She couldn't bring herself to tell her father so she confronted him and after a deep conversation between the two, Enji and Jack showed her what her family were really doing in America and more evils they were capable of.

Since June was adopted, she was never completely trusted, not that Hazashi actually trusted his family either. He kept a watch on her and figured out who the rabbit was and his weakness. Jack made his big move on the company but they were already prepared and after being cornered, Hizashi dropped a big secret that left their relationship in shambles. June was Hayato's baby sister Ichika, whom he thought died in the fire like his parents. They regrouping having luckily escaped and remained in hiding trying to figure out where to go from there.
