Shiboritoranaide, Onna Shounin-san

A vast underground labyrinth known as Tartaros attracts adventurers seeking treasure. Rabi, an inexperienced adventurer, faces repeated misfortunes within the dungeon. During one such incident, he encounters Philo, a half-beast character, and they form an agreement where Rabi becomes Philo's regular client. As Rabi continues his journey through Tartaros, he frequently purchases items from Philo.
