Fukuma, a sharp-eyed supporting character with black hair and glasses, exudes professionalism through crisp suits and ties. He manages Bosatsu, a vampire cat inherited from a prior guardian, subtly weaving supernatural duties into his responsibilities. His calm, methodical demeanor in professional environments contrasts with an unrelenting adherence to protocol, underscoring a disciplined work ethic. Renowned as "every author's worst nightmare" in his editorial role, he imposes meticulous standards and rigorous revisions, generating friction with creative collaborators. This dynamic positions him as a deliberate instigator of strategic pressure, though his personal history and deeper motivations remain deliberately obscured.
