man who is obsessed w/ working out, starts out as a C+ rank. he works out at the abyss but misunderstands where to train. so he wanders in the abyss and faces high-leveled monsters while the soon-to-be contractor of him cannot find him. since the time in the abyss goes much slower than on earth, he ends up defeating monsters, to bosses, and finally becomes a human constellation after 100 thousand years. he does this in order to hope that the earth hasnt been attacked by the evil constellations according to the prophesy that is not necessarily reliable (most likely true though). now, he's back on earth and meets some old friends who became high ranked individuals. in order for the other constellation to not find out that he is here, he conceals himself and gains more followers to become more powerful as a constellation.
