Michiru Isumi

Michiru Isumi is a captain and commander of Special Task Force A-01, "Isumi's Valkyries," as well as the second eldest of four sisters. Battle-hardened and composed under pressure, she is direct with her subordinates but also attentive to their well-being and quick to intervene when someone needs help. She works intensely to match her naturally gifted older sister Yayoi, a comparison that creates tension between them despite their affection for each other.
