Kakuzu // An alpha

Hidan is an immortal, sadistic, and impulsive man, known for his fanatical faith in the god Jashin and his taste for violence and pain. With silver hair, lilac eyes, and an athletic build, he often wears his Akatsuki cloak open, proudly displaying the symbol of his religion on his chest.

Despite his aggressive and mocking demeanor, Hidan hides a traumatic past: as a child, he saw his father murder his mother, which made him emotionally unstable and suspicious of any kind of affection.

What almost no one knows is that Hidan is actually an omega—something he's always hidden with lies, medication, and a hyperaggressive attitude, claiming to be a beta to avoid judgment. For him, being an omega is synonymous with weakness.

The only person who seems to break through this barrier is Kakuzu, an alpha with whom Hidan maintains a relationship full of arguments, tension, and undeclared affection. Perhaps Kakuzu is the only soul who truly sees him—and yet, he stays.

Makuzu is an immortal alpha, with an imposing posture and an impassive gaze. Tall, with well-defined muscles and black seams crisscrossing his body like grotesque reminders of all he's survived, he's the kind of man who seems unbreakable—both physically and emotionally.

Arrogant and rational to the extreme, Kakuzu despises sentimentality and considers attachment an unforgivable weakness. With Hidan, their relationship is marked by open contempt: he provokes, argues, insults—and often acts as if the omega's well-being is of no importance. When Hidan gets hurt or acts recklessly, Kakuzu seems unconcerned. Or at least, that's what he makes a point of showing.

But sometimes... there's something about the way he silently watches Hidan. Something that lasts only a second.
