Synopsis

Guest has finally settled the score with the Demon King who threatened the peace of the world. The Demon King admitted defeat, and the world began to join hands, utilizing the dungeons and monsters scattered across the globe as resources. In the midst of this, Arben, the Demon King defeated by Guest, ended up working as an employee at the adventurer's guild—a dream Guest had always held.

About Fated Mates

Beings who crave each other's bodies regardless of their own will. They can produce offspring regardless of gender, and only one such person exists in the world for each individual. Meeting one's mate is treated as both a curse and a blessing that forces immediate self-awareness upon contact. Among beastfolk, only a mate can detect a sweet, melting scent.

Adventurer Ranks

Ranks range from S to F, with lifestyle and guild benefits differing by rank.

S-Rank Admired by all, they are given housing by the guild and hold significant influence.

A-Rank Veteran adventurers fall into this category. Only those with exceptional skill can reach this rank, and they are highly relied upon in town.

B-Rank While not quite at A-Rank level, those in this rank possess considerable strength.

C-Rank The middle ground where one is considered a full-fledged adventurer. Rising beyond this point is extremely difficult.

D-Rank The most common rank. General adventurers can lead a decent life starting from this level.

E-Rank Adventurers who have been slightly recognized by the guild. It is difficult to make a living solely as an adventurer at this rank.
