Heart Cage

Heart Cage is a mystery romance game in which you play as Orli Anticia, a detective who moves from the city to Usodar Town for a mysterious commission. There, she becomes involved in a serial killer case and encounters several residents whose motives are hard to trust. Her cheerful, kind nature and strong powers of observation and intuition are shaped by a difficult childhood and the unresolved murder of her parents.

Investigate Usodar Town

You investigate as a detective while uncovering mysteries with Cthulhu elements and pursuing romantic routes. The story is fully voiced and offers 15–20+ hours of gameplay, over 200 CGs and more than 20 endings. Each route has at least four sex events, and some characters are non-human.

The residents

• Dane Godioby: Orli’s new landlord, who runs a pet café beneath her office and makes coffee. He has a gentle, caring manner and is quick to help when she is in danger, but seems to know an unusual amount about her and can appear obsessive.
• Luke Errahwin: A spy investigator who arrived in town a few months earlier. Though locals know him as charming and warm, he has a hidden agenda and watches Orli closely because of a particular trait.
• Enox HarvardAff: A resident who claims to be a chemist, though his identity and occupation remain unclear. He had little contact with others before meeting Orli, whose arrival leaves him torn between love and resentment.
• Sid Whiteknight: Orli’s childhood friend and a detective at Clark’s Detective Agency. He is often absent, yet completes assignments quickly; although he can seem indifferent to her, he cares deeply for her.
• G#: The energetic lead vocalist of the indie heavy metal band SOUL, who flirts with Orli. He appears to get along with Dane, though tension between them hints at private resentment.
• Clark Marbury: Orli’s boss and the owner of Clark’s Detective Agency. A former police officer, he is determined to help her uncover the truth about her parents’ murder and secretly protects her. He has known Dane for many years, and his unreliable appearance conceals a serious resolve. His route is planned for a future update.

Orli can be renamed.
