Mitsuhide Akechi is a supporting character in the anime Sengoku Night Blood, depicted as a loyal retainer within the Oda faction. His backstory is rooted in a single act of betrayal against his lord, Oda Nobunaga, for which he was subsequently forgiven. After receiving this forgiveness, Mitsuhide swore an oath of eternal loyalty to Nobunaga, an event that fundamentally shapes his present actions and motivations.

Personality-wise, Mitsuhide is earnest, serious, and reserved. He performs his duties quietly and without fanfare, embodying the role of a loyal philosopher. Despite his past transgression, he is not driven by fear of death; rather, his continued existence is wholly dedicated to Nobunaga, as reflected in his statement that only Nobunaga keeps him alive. This dedication defines his role in the story, as he serves as a dependable and contemplative member of Nobunaga's forces.

In terms of key relationships, his bond with Nobunaga is the most central. Their dynamic is defined by a profound debt of gratitude and a second chance, which Mitsuhide honors through unwavering service. His interactions with other members of the Oda clan and the story's protagonist, Yuzuki, are filtered through this primary loyalty and his serious demeanor.

Mitsuhide's notable abilities are not extensively detailed in available sources, but his characterization as a vampire in the Sengoku Night Blood setting implies superhuman physical traits common to his kind, such as enhanced strength and speed, as well as pointed ears that distinguish his appearance. He has lilac-colored hair and blue eyes. His most prominent ability, however, lies in his steadfast resolve and philosophical outlook, which allow him to carry out his duties with quiet competence and a clear sense of purpose.
