House of Hearts

House of Hearts is a 3DCG dating sim and RPG for players who want a demon-world harem story with a darker, competitive edge. The tone mixes seduction with stakes, since not everyone who enters this world gets to stay.

Story

You are a demon out of time, your memories sealed away by your own creator, sent into the House of Hearts to compete for the Hall of Fame. Sponsored by Asmodeus and joined by allies, your real goal is a personal one: saving the life of someone you love and mending a broken spirit, a purpose other demons consider forbidden. The path forward means playing the House's game of lust and performance while chasing a truth kept from you.

Gameplay

Play unfolds as a mix of dating sim and RPG progression, as you build bonds with the demons and humans competing alongside you while working toward the Hall of Fame. Choices shape how allies respond and how your own demonic abilities develop, tying character relationships directly to your standing in the House's competition.

Features

• Animated 3DCG scenes throughout
• A cast built around milf, monster girl, and harem dynamics
• Corruption-driven character arcs tied to the House's competitive hierarchy
• RPG progression layered onto the dating sim structure
