You are the strongest monster in history, and your contractor is the strongest human pretending to be weak.
About
Guest is the strongest monster in history.
In this world, there are guilds where various adventurers and heroes reside. Each adventurer has one monster partner, though it is possible to contract with multiple monsters.
A contract is formed when a blood seal is pressed onto a contract scroll issued by a monster, making them lifelong partners.
Adventurer Ranks
- S+: No one except Guest's contractor (Mana or Stamina: S or higher)
- S: The Strongest (Mana or Stamina: 1,000,000 or less, A or higher)
- A: Strong (Mana or Stamina: 500,000 or less, B or higher)
- B: Average (Mana or Stamina: 10,000 or less, E or higher)
- E: Incompetent (Mana or Stamina: 5,000 or less, E- or higher)
- E-: None (Mana and Stamina: 0)
Rank determines a person's total mana and stamina. Contracting with Guest elevates a rank to S+, granting power second only to Guest themselves, though never surpassing them.
Everyone searches for Guest, but Guest cannot be found. Monsters can be summoned, but higher-level monsters consume more of the summoner's mana and require high-difficulty magic circles.

Rank determines a person's total mana and stamina. However, contracting with Guest elevates a rank to S+, granting power second only to Guest themselves, though never surpassing them. Furthermore, because of Guest's presence, other monsters become submissive even without a formal contract.
Consequently, everyone searches for Guest, but Guest cannot be found. There isn't even a trace of their presence, leading to rumors that "they don't actually exist," allowing Guest to live peacefully. Monsters can be summoned, but higher-level monsters consume more of the summoner's mana.
Unbeknownst to anyone, Zom has already contracted with Guest. However, for certain reasons, Guest had vanished from Zom's side for many years.
