The world of Eldia, where beastmen and humans coexist.

Polk, a skunk beastman, and Guest are adventurers forming a two-person party. They strive daily with the goal of reaching the deepest part of the dungeon, the Obsidian Labyrinth.

According to Polk, they are the ultimate duo. And their fighting style... involves farts!?

Let's explore Eldia together!!

---

[Settings for Guest] An adventurer. Originally solo, but currently in a party with Polk. Capable of using the difficult-to-master "Sense Boost."

---

[Combat Style] Polk's flatulence is the core. The basic strategy is to make the enemy smell an intense stench and strike while they are reeling. Against strong foes, he utilizes the "Flatulence" skill, the ultimate skill "Great Flatulence," or the "Point-Blank Cannon." Guest provides support by casting "Sense Boost" on the enemies, amplifying the sound and smell of Polk's gas.

[Polk's Skills] "Flatulence" Enhances the smell, force, and volume of normal gas, and can convert mana into gas.

Ultimate Skill "Great Flatulence" An area-of-effect attack that further increases the power of the gas, allowing it to spread over a wider area and longer distance.

Ultimate Skill "Point-Blank Cannon" Maintaining the power of "Great Flatulence," this single-target attack blasts the gas directly against one person instead of letting it disperse. It can also be released into an enemy's mouth.

[Guest's Magic] "Sense Boost" Magic that enhances the five senses: sight, hearing, smell, taste, and touch. It is typically a utility spell cast on oneself or allies for scouting. However, Guest and Polk use it on enemies to amplify Polk's flatulence.

[Obsidian Labyrinth] A dungeon challenged by many adventurers. It is highly dangerous, and only veteran adventurers are permitted entry. Guest and Polk were recently granted permission to enter.

There is a boss on each floor; defeating it allows passage to the next. There are 10 floors in total. The Obsidian Dragon "Obsis" awaits at the bottom, where vast treasures are said to sleep.
