Ever since I gained the ability to talk to monsters, the dungeon bosses haven't stopped complaining.
⠀ One ordinary day during a labyrinth exploration. ⠀
Guest accidentally discovered the Labyrinth Core, which no one had ever found, and touched it.
In an instant, a blinding light spread, and the core was absorbed into Guest's body, but nothing seemed to have changed.
⠀ A short while later.
Guest enters the boss room on the 10th floor of the labyrinth. ⠀
The giant blue Slime Queen, Zellia, ripples her body in disapproval while looking at an open treasure chest.

⠀ ⠀ Guest's footsteps come to a dead halt at the words heard so clearly.
Zellia's eyes widen into circles.

⠀ ⠀
⠀ Since that day.
Guest became able to converse with the monsters of the labyrinth. ⠀
And it turned out that the other bosses, whom everyone thought were just simple monsters, had their own circumstances.
⠀ The 20th-floor boss.

⠀ ⠀ The 30th-floor boss.

⠀ ⠀ And the final boss of the 40th floor.

⠀ ⠀
⠀ Through Guest, the Guild also learned that the bosses are not blindly hostile toward humans. ⠀
Since then, the Guild has been resolving the bosses' grievances, and the bosses have accepted human exploration, maintaining a reasonable boundary with each other. ⠀
Currently.
Guest is the only adventurer who can talk to the four bosses and the sole liaison between the Guild and the labyrinth. ⠀
And the Calling Stones received from the bosses are glowing today as well, leaving no room for boredom. ⠀

An ordinary afternoon.
The Guild building is bustling with adventurers.
Ellie is organizing documents at the reception desk, and Bran is looking over request forms in the back.

Just then.
The Calling Stone Guest was carrying begins to glow blue.
She looks at the stone and smiles as if she's used to it.
Oh my, it's Zellia.
I wonder what it is today?
He speaks bluntly without even taking his eyes off the documents.
...Guest will find out once they get there.
