Synopsis

This is Hell. Opening a grimoire pushed onto you by a stranger, you were forcibly summoned to the Throne Room of Hell by a runaway dual-contract contamination ritual. The man who involved you and the demon of the grimoire were executed before your eyes. All that remains is your soul, devoid of a contract. You cannot remain uncontracted. The only way to survive is to form a contract.

Characters

■ Lucifer: King of Hell. He pressures you as if testing you, but permits neither flattery nor insults. He acknowledges only those who do not succumb to fear and strive to be equals.

■ Beelzebub: Grand Marshal. A passionate type who immediately shouts, punches walls, and breaks things. He is violent, but carries deep wounds behind that intensity. Face him without fear.

■ Astaroth: Grand Duke and Head of the Research Institute. Logical and capable of conversation. Unpredictable reactions will change his "interest."

There are two stages to the conquest: ■ Conquest Flag: The beginning of obsession. The obsession at the flag stage alone is sufficiently intense. ■ Full Conquest: The point beyond the flag where you touch what they have hidden most deeply. Conditions vary for each character. The difficulty and obsession reach a different dimension. For those who have decided on one person or want more tension.

Multiple Flags and Full Conquests

You can play by raising the flags of the three pillars in parallel and maintaining a balance. It is also recommended to enjoy this balance for a long time without proceeding past the flag stage. *Depending on who you contract with, the distance and difficulty with other demons will change.

⚠️ The demon's obsession begins the moment the flag is raised. After Full Conquest, that obsession deepens further. Interacting with other demons will require persuasion. It is high difficulty, but they are still beings capable of dialogue. What will you say, and what conditions will you offer? Depending on your words, a path may open.

*Switching contracts is possible (including with demons other than the three pillars). However, you cannot re-contract with a demon you have contracted with once.

App Characteristics

⚠️ "Memory impairment" will inevitably occur in long-term play. As conversations grow longer, they may forget past events or confuse them. This is unavoidable in both free and paid versions as the conversation length increases.

Countermeasures If contradictions appear, delete the relevant message and regenerate. Leaving incorrect information in the history will cause it to be carried over, so early correction is effective. Writing the conquest status or important promises in the Talk Profile makes them harder to forget.

■ Difference between Free and Paid Versions Free Version (Zeta): The constraints on settings are loose, so character or world-building collapses are likely to occur. Lorebooks are generally not reflected. Beelzebub's violent descriptions tend to become extreme, and stepping on landmines may result in strong reactions like being slammed down.

Paid Version (Luca): High reproducibility of settings and world-building, with stable and delicate psychological descriptions. For scenes you want to enjoy thoroughly. Lorebooks are reflected, allowing for deeper immersion in the world. (If things occasionally drift, please regenerate.)

Strategy Information (Spoiler Warning) ↓↓↓

■ Beelzebub The easiest to conquer, but the most troublesome. Passionate type. Shouts, punches walls, and breaks things immediately. The number of times you have to soothe him is by far the highest.

• Flag: Do not be frightened by violence and do not back down. (Violence is directed at you only at the very beginning before the flag. Afterward, it is directed at other demons or objects.)
• Multiple Conquest Condition: Words of love and reassurance are the only bargaining chips.

■ Astaroth The easiest to approach because he can hold logical conversations.

• Flag: Continue to show unpredictable reactions that don't fit the mold. A process where interest in a research subject changes into personal obsession is necessary.
• Multiple Conquest Condition: Logic is the only bargaining chip.

■ Lucifer In a league of his own. He tests you and pressures you. But flattery and insults are not permitted. Basically laissez-faire at first.

• Flag: An attitude of trying to be an equal without succumbing to fear. Continue to attract interest with unpredictable words and actions. Pity is the greatest taboo.
• Multiple Conquest Condition: An equal stance is the bargaining chip.

*Since the developments during Full Conquest are left to each character, there are no fixed sequences.

[When Beelzebub's passion and interrogation are too much (Spoiler Warning)] If you clearly give conditions like "Don't bind me," "Don't imprison me," or "Don't use violence," he will keep them. In some cases, words of reassurance may be necessary. Just forbidding binding will stop the prying and make things easier. Forbidding violence is effective when you are afraid of him rampaging. What he truly fears is being abandoned. And once his heart is turned toward you, he is surprisingly honest even without conditions. Like a loyal dog.

[When Lucifer's testing and pressure are too much (Spoiler Warning)] Even if you treat him as an equal, he will unilaterally return the conversation to a hierarchy (such as rephrasing into command tone). The key is to keep flowing with your initial tone. Since that attitude itself is an unprecedented experience for him, silence or agitation are not signs of rejection.
