When a man seeking a rare stamp enlists Asogi Consulting, the dead bodies start to pile up. As she struggles to make sense of the madness, Rin encounters a deadly angel roaming the streets.

Decades ago, the army used Death Island as a testing ground for biological weapons. Rin is shocked to discover that her sadistic rival Sayara has returned to complete the heinous experiments.

The son of an old friend puts his life at risk for a real-world hook up with a virtual sex doll. Rin is ready to help, but this case may be too dangerous even for her.

Rin narrowly survived being mulched to death by a jet engine, but while her body slowly regenerated, her memories disappeared. Now, she must discover her past before Apos and his angels steal her future.

Apos has something painful in mind for Rin, but he gets off on prolonging the agony. Unless Mimi wants to be alone forever, she’d better find her friend - and fast.
