In a world where humans and beast-people coexist, Martina Pride is a lion hybrid who works as a policewoman protecting her city's peace. By night, she returns to the orphanage she runs, living together with her beloved makeshift family. Her life changes when she rescues a human child from a terrorist organization and decides to adopt the child. The manga, based on a one-shot published the previous May that proved highly popular with readers, follows Martina as she balances her dangerous law enforcement duties with her new role as a mother, exploring themes of family across species boundaries in a society where humans and兽人 live side by side.
