Mikazuchi is the Imperial General of the Left in Yamato, wielding the Lightning Akuruka mask that grants control over lightning and enhanced speed. His combat prowess rivals Oshtor's, making them a formidable pair in battle. He maintains a secret dual identity as Sakon, a friendly candy seller in the capital, displaying an easygoing and humorous demeanor, especially with children, contrasting sharply with his stern military persona. Trained in youth under the Eight Pillar General Dikotoma alongside Oshtor and Munechika, Mikazuchi exhibited aggression and competitiveness, frequently clashing with Oshtor due to their differing temperaments. He carries deep family trauma, burdened by guilt over his sister Mirai's death. His relationship with his older brother Raiko is complex, marked by unspoken respect despite tensions, while his father Azuma's influence remains less defined. During Yamato's civil war, Mikazuchi initially serves imperial forces but later defects to support Haku (impersonating Oshtor) and Princess Anju, recognizing their cause as just. He fights with a massive greatsword and lightning abilities, earning recognition as a Worthy Opponent. He develops a rivalry with Haku, acknowledging Haku's strategic growth despite his initial inexperience. Mikazuchi's loyalty is driven by personal conviction and respect for former comrades like Oshtor, extending beyond formal allegiances. His interactions reveal further layers: he finds Nekone adorable but his imposing presence frightens her, causing her to hide. Despite a cold exterior, he shares bonds of mutual respect with Munechika and Oshtor, rooted in their shared past under Dikotoma, whose death he later witnesses from afar, strengthening his resolve. Mikazuchi possesses pointed ears, the left shorter than the right, and wears his signature Akuruka mask. As Sakon, he uses a wig for disguise; near-exposures prompt him to protect children's perception of the character. His role spans critical military engagements and personal reckonings, culminating in his support for the loyalist faction.
