It's not easy balancing between getting a university degree and managing an intergalactic space police corps, but, well, somehow Tenma manages. At least he's got friends from all over the universe to help him! And coffee. Lots of coffee. Maybe it would be a little easier if there wasn't a conspiracy to destroy them all. Or: after the Grand Celesta Galaxy, the universe signed a treaty for interstellar peace. It's not as great as it sounds, especially when said universe is full of dark secrets and a single wrong move could get you killed. Tenma's trying his best though.
