Norihito - The Japanese Psychopath

After causing of that problems in his old job and losing his wife to his boss, Norihito ended up getting totally crazy. He tried to kill himself, but it only ended in accident that caused brain dysfunction.

He discovered an incessant thirst for killing, torture and blood.

But this also made him very smart, so he sued his boss and managed to win the old man's entire company with false evidence (in addition to the main evidence) and remarried Hisato. But it was just for his own pleasure to make him want to kill her even more.

Now, we will see his everyday while he tries to escape his personal hell, perhaps by being noticed for his actions or at least distinguished from his hollow peers (which will always fail).
