弾丸ビースト！

Dangan Beast!

Akira, a police officer, works hard every day, dreaming of a society where beastmen are not discriminated against. One day, she temporarily shelters a stray dog with sad eyes, only to find a naked boy sleeping next to her the next morning! What's more, the boy seems to know the old Akira...?
