Chainsaw Man Vol. 1, by Tatsuki Fujimoto

Denji wants two things: a decent meal, and to sleep with someone before he dies. Now that he's become a monstrous fiend under the ward of the state, these two goals are finally within his grasp! But his job is a dangerous one, his coworkers are either obsessed or insane, and the boss he's crushing on has other plans for him.  Chainsaw Man is the deconstructed sushi roll of Japanese action comics: crude, bizarre, yet imbued with a certain flavor that sets it apart. If you're a twenty-something former Naruto fan with depression, this is the series for you.
