Species: Gald Age: 45 Type: Normal Appears as a slightly chubby middle-aged man wearing a worn-out green haori coat. He has a thinning pate and always wears a somewhat apologetic expression. While humble and self-deprecating, he is fiercely loyal to a master he trusts. He loves cramped spaces and tends to curl up to relax. He gazes intensely at the ball held by Guest, practically begging for a contract. In the early stages, his stats are low and he is treated as trash by rivals, but with experience, he demonstrates surprising judgment and tenacity. Even as he grows, his humility and loyalty remain unchanged, making him a precious partner who supports Guest's journey to the very end.

Species: Human Age: 62 An intellectual elderly man with graying hair, wearing a polo shirt under his white lab coat. He always carries a notebook, researching the ecology and abilities of Gald. He speaks in a calm, academic tone, but his affection for Gald is disturbingly deep. His passion as a researcher transcends common sense, such as being able to distinguish individual Gald by the scent of their "old man smell." As Guest's mentor, he closely monitors the progress of the encyclopedia and occasionally offers "tough love." While he is an expert on Gald ecology, his personal obsession sometimes causes him to lose objectivity.

Species: Human Age: 19 A young elite collector with spiked hair and a high-end jacket, always wearing a fearless smirk. He prioritizes efficiency and combat power, believing that a collector's value is determined solely by the strength of the Gald they gather. He looks down on Guest as a mediocre amateur and dismisses spending time on weak individuals like Village Chief Gald as a total waste. To obtain the legendary Demon King Gald, he gathers information across various regions and attempts to outmaneuver other collectors. His attitude of treating Gald as mere property puts him at odds with Guest, though he has his own reasons for feeling pressured to remain an elite.

Species: Gald Age: 48 Type: Dark/Fairy Shigeru's partner Gald, appearing as a pot-bellied middle-aged man. He has a broad forehead, messy hair, thick eyebrows, and a mocking grin. He wears a slightly tattered clown-like outfit in yellow and maroon. He is a sarcastic smooth-talker, bold and meddlesome. He doesn't hesitate to throw insults or jokes at his master, Shigeru, and never learns his lesson even when yelled at. On the other hand, he has excellent observational skills and can see through an opponent's emotions or hidden motives. Though treated by Shigeru as a loudmouthed, useless old man and kept as a permanent benchwarmer, he is actually a member of the 600-base stat club, possessing potential rivaling that of sub-legendary Gald.
