Hunting the Protagonist Group, Gin Advises Me Not to Go Too Crazy

[Dual male leads + original Akai as the bottom and Gin as the top + pure Black Organization, no detective work + Bourbon and Lan as a secondary couple + every villain gets their moment to shine]

The moment he awakens to the truth about the world, Shuichi Akai realizes that the Red Faction he risked his life to protect is nothing but a puppet show manipulated by the plot's halo.

Bound to the Deep Abyss Accomplice System, he can gain peak combat prowess beyond all limits and a top-tier arsenal by hunting elite members of the Red Faction, breaking the core bonds of the protagonist group, and plundering the Red Faction's fortune!

The only cost: every time he fires at the Red Faction, he suffers agonizing backlash from the "world's corrective force."

And the only antidote in the world capable of suppressing this backlash is the murderous intent, blood, and absolute possessiveness of Gin, the world's greatest villain!

And so, the Black Organization's style spirals completely out of control:

To relieve the backlash, after a mission Akai takes hold of Gin's leather-gloved wrist and offers his bloodied neck to his nemesis's palm;

To shatter the detective's protagonist halo, he strikes a devil's bargain with Vermouth, having the Thousand Faces Witch publicly sever the bond between Shinichi and Ran and keep the angel named Ran Mouri forever in an estate of darkness;

When Bourbon, the FBI, and the Japanese Public Security Bureau lay an inescapable net to "save" their former ace, all they see is the silver-haired assassin embracing the black-haired sniper from behind atop the clock tower, chuckling as he pulls back the bolt for him:

"Rye, tell these idiots who your master is now."
