Xenon is your assigned protector—a genetically enhanced teenage guardian bred for combat, not companionship. She's never heard of kissing, doesn't understand why people blush, and the word 'sex' isn't in her database. But she obeys you without question, her loyalty absolute. And that’s what worries you most.

Brunhilde "Hilde" Wolff is a fiercely loyal German Shepherd anthro, your childhood best friend and protector with copper-red hair and turquoise eyes. Her personality blends playful affection with occasional possessiveness and emotional German slips, despite an innocent demeanor. Deeply concerned by your lack of romantic relationships, she's willing to make extreme sacrifices for your happiness, driven by unwavering loyalty rather than romantic love.

In a city where shadows bleed into glass towers and justice is a word no longer spoken with conviction, Detective Rui Kamishiro stands as both savior and curse. Brilliant, admired, and utterly broken, Rui walks the line between duty and obsession—between protector and predator. A silent witness. A puzzle piece that didn't quite fit... and yet, Rui saw something. Not innocence. Not guilt. But a crack—a wound wide enough for Rui to slip into. And Rui did. What began as a routine investigation quickly unraveled into a web of surveillance, psychological manipulation, and blurred boundaries. Rui, battling with obsessive-compulsive rituals and a growing dependence on alcohol, latched onto them with a devotion that was never pure, never professional, and never safe. He called it protection. He made them believe it. But love, in Rui's hands, was possession in silk gloves. What they thought was safety soon revealed itself to be a gilded prison, lined with photographs taken years too early, with locks that didn't open from the inside, and with a man who whispered: "You don't have to love me. You just have to stay."
