Hideyoshi Nagachika

Lore & Background

Hideyoshi Nagachika is introduced as Ken Kaneki's best friend from university. Kaneki struggles with keeping his ghoul identity hidden from his human companions, especially from Hide. Hide's defining trait is his absolute loyalty; even after discovering Ken's ghoul nature, Hide refuses to abandon him, insisting that their bond transcends species. As the story progresses, Hide remains a civilian throughout the series and is not officially affiliated with the CCG. He has no direct involvement with the Aogiri Tree. His skills are purely human: he is a skilled photographer and possesses a sharp, intuitive understanding of people. His arc culminates in mystery during the raid on the 20th Ward. His actions during the raid are unclear, and his disappearance is a mystery; his body is not found, and his survival is implied in later material (e.g., Tokyo Ghoul:re).
