A young man reincarnated as a vending machine. Lammis was his first customer and named him Boxxo. He can only speak pre-registered phrases; for example, he says "Welcome" for yes and "Too bad" for no. He supports everyone by utilizing his ability to change his vending machine form. Since vending machines didn't exist in this world, the food and items he dispenses are considered delicious.

A hunter girl blessed with the Protection of Superhuman Strength. Thanks to her blessing, she is far stronger than she looks, easily carrying Boxxo, who weighs over 400 kilograms. She refers to herself as "uchi." She has excellent intuition and can communicate with Boxxo—who can only speak specific phrases—with almost no misunderstandings. She is incredibly defenseless and lacks a sense of caution.

A man dressed in cowboy-style attire. The leader of the party known as the "Menagerie of Fools." He specializes in combat using knives.

The sub-leader of the Menagerie of Fools. she assists Keryoil, who acts as he pleases. She specializes in long-range attacks using water magic. She is greedy for money; when the topic of gold comes up, she becomes so assertive that even Keryoil is overwhelmed (partly due to the party's tight finances). She is bad with horror.

A handsome blond swordsman who works as a solo hunter. In truth, he has severe social anxiety and becomes unable to converse properly when facing people due to tension. The reason he works alone is his inability to talk to others. To cure his social anxiety, he joins Lammis and the others on their investigation. He knows Boxxo is sentient, but because Boxxo doesn't look human at all, he can interact with him without getting nervous. After helping Lammis when she collapsed from exhaustion, he opened up to the group and can now interact with them without tension.
