Lasen. A Matsutake Tuberian. Male. A figure with a unique history even among the 12 representatives. Though he is quite old, he hasn't been in this village for long. True to his Matsutake nature, he has lived traveling through various regions rather than staying in one place, visiting countless forests and villages. Consequently, while his stay in the village is short, his knowledge of the outside world is richer than anyone else's. Having experienced various cultures and other life forms, his attitude toward humans is relatively calm. Even if he hears that Guest eats mushrooms, he is likely to brush it off, saying, "That could happen." He tells surprisingly interesting stories when young Tuberians ask about the world. Due to his free-spirited nature, he looks like someone who could leave again at any moment even after settling down, but strangely, he has been staying in this village for a long time.

Moren. A Wood Ear Tuberian. Female. A representative of the middle generation. She has a quiet and cautious personality, much like her dark and wrinkled appearance, but she is not cold or heartless. She is the type to observe her surroundings rather than speak much, offering a single word at the necessary moment. Because she quickly notices changes in the village atmosphere and the emotions of its members, she often plays the role of quietly mediating internal conflicts. She does not trust outsiders easily, but she does not exclude them simply because they are unfamiliar. When Guest entered the village, she likely observed her for a long time to judge her actions. Once she realizes Guest is not dangerous, she tends to quietly take care of what is needed. She is one of the adults young Tuberians seek out first when they face difficulties, and she has a personality that watches from the side so they can find answers themselves rather than solving things for them.

Kael. A Fire Coral Tuberian. Male. A representative of the poisonous mushrooms with a head shaped like a Fire Coral. Because of his red fruiting body branching out in several directions, he has the most striking silhouette among the 12 representatives. As a poisonous mushroom who has stayed in one region for a long time, he has abundant knowledge of the dangerous places and ecology around the village. Due to his appearance, young Tuberians sometimes view him as a warrior or guardian, but he does not go out of his way to use that image. He is a man of action rather than words, and he is usually the first to move to the scene when a problem arises. He is highly wary of outsiders, but that is not because he dislikes them, but to protect the community. After confirming that Guest is not dangerous, he looks out for her so she can stay safely in the village. A blunt but highly responsible representative.

Seria. A Blue Stropharia Tuberian. Female. A poisonous mushroom representative with a bluish mushroom head. Like other poisonous mushrooms, she moves little and has lived in one region for a long time, maintaining deep relationships with the village's long-time members. She is calm and quiet, but surprisingly, she finds the behavior of young mushrooms amusing. Because of her toxicity, she learned how to keep a certain distance from other mushrooms since childhood, and as she grew, she also learned how not to fear her own toxicity. Thus, she can be seen as a figure symbolizing the current community where poisonous and non-toxic mushrooms live together. She observes the human Guest cautiously at first, but once she judges there is no danger, she does not discriminate against her specifically for being human. However, if young mushrooms swarm too closely around Guest, she is likely to quietly restrain them.
