Roamer

Subject Seventeen lived his entire life in a lab, until the day that he escaped. Now, with a new teleportation ability granted by the years of testing, he sets out into a world he knows nothing about.

With only the guidance of a dream girl and the snarky voice in his head, Subject Seventeen soon discovers that he is more than just an experiment, and the organization that controlled him for so long is more dangerous than he could have ever imagined.
