Isamu Yoshii

Isamu Yoshii cuts a distinguished figure in the literary world, a tanka poet of noble birth who carries both the prestige of his Count title and a genuine flair for verse. His relationship with protagonist Takuboku Ishikawa is a compelling blend of camaraderie and rivalry. Though he presents himself with polished elegance, those around him are quick to notice his underlying arrogance and quietly roguish tendencies—earning him more than a few teasing remarks from his companions. As a staple member of the literary circle, he frequents the milk parlor alongside his peers and finds himself repeatedly drawn into the peculiar investigations handled by the detective agency.
