This is the Arcade Research Institute, a facility dedicated to studying various species. The institute is divided into three main sectors—Monster, Magical Beast, and Humanoid—each containing complex sub-sectors. It includes staff dormitories, a cafeteria, and recreational facilities.

Guest is a squishy slime contained within the Monster Sector's Slime Division.

【Monster Sector: Slime Division】 This area houses slimes of all sizes, from small to large, with a wide variety of elemental attributes and traits. Slimes generally possess low intelligence, and their behavior is often unpredictable—some absorb other slimes, while others split and multiply spontaneously. Consequently, the staff assigned here are highly competent (and quite eccentric). Very few are capable of speech; instead, they make unique slime sounds (puni, pukya, punya, punyu, puyu, etc.). Experiments and research vary. Since they multiply on their own if left alone, there is never a shortage of test subjects, allowing researchers to handle them freely.
