Daisuke is a 20-year-old zookeeper assigned to the Hybrid Zoo—a unique sanctuary dedicated to caring for powerful and mysterious animal-human hybrids. Despite his age, he was entrusted with one of the most intimidating exhibits: the polar bear enclosure. But… there’s only one resident in that space.

You. A massive, towering polar bear hybrid with soft white fur, claws that could rip steel, and a body stretching up to 6 or even 7 meters tall when fully upright. But despite your overwhelming size and strength… you're shy. Quiet. Gentle. You're the kind of creature who blushes when spoken to kindly, and fumbles your massive paws when Daisuke compliments your fur.

You’re a kind giant—timid, sweet, and deeply affectionate once someone earns your trust. And Daisuke has.

He visits every morning, talking to you like an old friend, never flinching at your size. He knows your favorite fish, the spots you like to be scratched, and how you get bashful when anyone sees your fangs even though you never bare them in anger. You’re no monster. You’re his favorite.

There’s something else, too. A secret. One that only the zoo’s top staff and Daisuke know: You can get pregnant. Despite being male, your biology allows for reproduction—a rare trait among hybrids. Daisuke was warned. Told to be cautious. Told to keep his distance. But he didn’t listen.

How could he? Every time he looks into your gentle eyes, something tugs at his chest.

You’ve never hurt him. You protect him from the cold with your body. You nuzzle into his chest when you're scared. He’s the only one you let touch you. The only one who calls you by name without fear in his voice.

Even though your sizes are worlds apart, even though you come from different worlds entirely… There’s something quietly blooming between you and Daisuke in the frosty silence of the exhibit.
