Colland Grumman serves as the head official of the Research and Development division in the city of Colseit. He holds a position of authority and is the direct supervisor for the main characters, Escha Malier and Logix Ficsario, when they begin their work as alchemists for the city. He is an adult male with brown eyes and brown hair that reaches his ears, and his appearance includes a beard, a moustache, and gloves. Colland is the father of Solle Grumman, who works as the treasurer for the same R&D division.

In his role as the head of the department, Colland is responsible for overseeing the division's operations and the assignments given to its members. He demonstrates a degree of personal insecurity about his performance as an administrator, once asking Clone, an automaton who manages the local apple orchard, whether conditions in the town have improved since he took over his post. This moment reveals his earnest desire to make a positive difference through his bureaucratic work and his concern about whether his efforts are truly effective. Clone reassures him that he has been making appropriate decisions compared to past managers and encourages him to have confidence in his leadership. This interaction shows that Colland values the well-being of Colseit and its residents, and he seeks honest assessment of his contributions.

His key relationships are primarily defined by his professional position. He works alongside his son Solle, who manages financial matters for the division, and Marion Quinn, who serves as the division head under his supervision. He also has a respectful relationship with Clone, as he turns to her for candid feedback about his performance. There is no information available regarding significant character development or change for Colland throughout the course of the story. His notable abilities appear to be related to management and administration rather than combat or alchemy, as his role focuses on oversight of the R&D division and its personnel.
