The Max-Level Player Is Rei Furuya's Own Brother!

Furuya Haruaki thinks he is the luckiest person in the world. He has a sweet, obedient, clever, sensible, and adorable younger brother who calls him big brother, and a beloved partner who seems cold on the outside but is warm inside, considerate and gentle, and takes meticulous care of him.

The only slight downside is that his partner and younger brother are always dressed in black for work. And black... is the favorite color of the archenemy he is determined to destroy: an organization whose members all use alcohol as code names. So black is the color he hates most.

But as a devoted partner and a good big brother, no matter how much he hates black, he would never let that make him resent the work his loved ones do. He simply supports them silently from behind.

Until one day, Furuya Haruaki sees two senior members of the organization captured by his subordinates: a brilliant blond, dark-skinned intelligence agent codenamed Bourbon, and a silver-haired man known as the Top Killer, codenamed Gin.

Furuya Haruaki calmly rubs his temples, then stares blankly up at the sky. Can someone tell him why these two members of the organization look exactly like his partner and younger brother?
