Heartsworn Abyss is a survival-thriller taking place in a modern dystopian world. Can Rei, a broken man whose life is on the mend, hope to oppose the sinister machinations of Saitou Corporation? Or will he and Akari be swallowed by Miyogawa‘s darkness, to be strung along like broken puppets?

SYNOPSIS: Rei Tsukiyora is a jaded man who runs a pawnshop in Miyogawa’s seedy underworld. One evening, he comes across a despondent Akari Hashimoto fleeing from her captors. Unable to abandon a young girl to the dangerous streets, Rei begrudgingly takes her in, offering her a reprieve until she gets her bearings in order. One thing leads to another, however, Akari’s stay becomes more… permanent then he had envisioned. For Akari, who has only led a high-flying life, and for Rei, a man who lives off the skin of his teeth, life together is… manageable (if not amusing). While Akari may have renounced her past life as a heiress, fate won’t let them go that easily. Akari’s entrancing looks and eminent status catch the eyes of Ryuichi Satou. As the head of Miyogawa’s largest company, he spares no resources on seducing her. An irate Ryuichi even accosts the pair at Rei’s residence, though Akari flatly rejects him. Humiliated, the scorned prodigy concocts a grand scheme that will lead to the hostile takeover of Akari’s company, and eventually, her heart. He swears to sully every fiber of her innocence. As for Rei… Ryuichi vows to bury him in an everlasting abyss. ABOUT THIS GAME: Heartsworn Abyss is a voiced visual novel, a Japanese genre that combines narration with beautiful anime illustrations, music, and voice acting. Gameplay primarily consists of reading with a few interactive elements (mainly limited to advancing the text on screen). Nothing in Heartsworn Abyss is sourced from AI, and we intend to keep it that way moving forward!
