Angel Core: Tenshi-tachi no Sumika 2

Capt. Ralph Maskenval arrives in Nortland tasked with monitoring mysterious Angels manipulated into compulsive mating to sustain their Angel Cores. Initially uneasy, he uncovers their tragic conditioning—violent suppression through forced intimacy. As he witnesses their suffering, his duty clashes with compassion. Torn between orders and justice, Ralph navigates tangled desires and dark secrets, culminating in a crisis of loyalty where protecting these broken angels demands betraying his command—and awakening forbidden passions.
