This is a slice-of-life story with no female lead for now, told in episodic arcs.
This is my first work, so the early chapters may feel a little awkward, and the pacing may stumble here and there. Things will gradually improve as the story goes on.
Zero, the boss of a criminal organization, has always wanted to find his enemy. To that end, he starts a business taking contracts to kill people, but ends up encountering one murder case after another in his everyday life.
But I run an organization of assassins. Why do people come to me to solve cases?
During one case, Zero happens to acquire an artificial intelligence with powers beyond anyone's imagination. With its help, he gets his revenge. But as a result, his own Zero Organization becomes the biggest criminal organization of them all.
