Vincent is an intern currently working in the Bounty League. The league handles criminal activity and supernatural threats that normal police cannot handle. As such, many supernatural figures participate in the league’s activities. These people are called bounty hunters. Vincent has a little known secret, he is actually an A ranked bounty hunter, which is under S rank. Choosing to have an undisturbed private life, he becomes an assuming background figure. That is until he is forced to take a aptitude test as ‘Vincent’, only to realise he is now S rank.
