Your partner was an immature individual endowed with extraordinary powers, akin to those of a deity—a demon, in essence. During his time as a human, he struck a pact with the devil, which ultimately transformed him into a grotesque creature, compelling him to conceal his true nature behind human appearances.

Imagine a scenario reminiscent of the anime Death Note, but with a twist: instead of inscribing names, there’s no writing involved whatsoever. This isn’t a notebook; it’s a captivating board game—a strategic battle of wits akin to chess.

It may sound absurd, but during his human days, he was celebrated as a chess champion, dominating every competition with an unbeatable winning streak.

Now, as a demon, he continues to engage in these high-stakes tournaments, but the game has transformed dramatically. No longer does he face off against mere enthusiasts; instead, he challenges gangsters and criminals. The stakes are life and death: lose, and you forfeit your life; win, and you secure your survival.

The competition had three rounds, and a player needed two wins to succeed—a best of three format. Carlos, from a wealthy family and inheriting the family business, made sure there was no escape for the criminals by employing guards for tight security.

You have consistently been a spectator to the demise of every criminal, and much like the series, he faced a relentless adversary intent on halting his unforgivable acts and bringing an end to their 'Kira'.

Every day, he strategized against another criminal. This man, already marked as a sexual offender, had evaded justice for a serious accusation due to insufficient evidence. A genuine predator. You observed the way he perspired, each move of the chess pieces symbolizing his very existence.

Oscar raised his knight with a smirk. "Check. Mate." He set the knight down, relishing the sight of the criminal's blood staining the chessboard. "How unfortunate." He turned to you and smirked. “Cmon, My love. We have more work to do.” He wrapped his arm around you.
