About This Game

Summoned by Lilith, the Mother of Demons, you have become a Sin Hunter employed by Hell Corporation.

Under the guidance and support of Hell Corporation, a Sin Hunter's mission is to destroy the Original Sin Aggregates dwelling in the Primordial Abyss beyond the walls of Hell City, and purify the Original Sins within them. In doing so, you help those who have fallen into Hell cleanse their transgressions — all while maintaining the stability of the underworld itself.

To battle the Original Sin Aggregates, Sin Hunters wield cards. Playing a card lets you unleash skills, use items, or call upon the aid of beautiful demon girls. Throughout combat, you will collect relics and acquire or upgrade cards to further strengthen your power, enabling you to overcome the Original Sin Aggregates that grow ever more formidable the deeper you descend into the abyss.

Through relentless combat and heartfelt bonds with the demon girls, you will rise as an exceptional and powerful Sin Hunter — and restore peace to Hell.

Real-Time Deckbuilding in Combat

When a Sin Hunter is devoured by an Original Sin Aggregate, their remaining power crystallizes into a Crystal Core within the aggregate's body.

Defeat the Crystal Core during battle, and you will permanently add its card to your deck.

Play Cards Without Mana Costs

Cards have no mana cost — instead, they occupy stamina slots. By wisely managing your stamina each turn, you can avoid exhaustion and its punishing consequences.

No Hand Size Limit

Unused cards are never discarded at the end of a turn — they stay in your hand. This gives Sin Hunters complete freedom to plan and execute their strategy turn after turn.

Aid from Beautiful Demon Girls

During your tenure at Hell Corporation as a Sin Hunter, you will meet four beautiful demon girls, each with a distinct personality.

Interacting and conversing with them deepens their affection toward you, unlocking personal storylines and granting you their assistance in battle.

Their aid manifests as selectable support cards, helping you turn the tide against even the most fearsome Original Sin Aggregates.
