Nagi Tooma

As the owner of 'Black Cat House' in the imperial capital, he oversees the day-to-day care of the autonomous dolls who work within the café. A veteran of the great war who once served as a technical officer in the Imperial Army, he welcomed several war-damaged dolls into his care after leaving military service. Though his demeanor appears easygoing and difficult to read, he holds an unwavering belief in the potential and warmth of dolls that surpasses anyone else's, quietly watching over them from the shadows and dedicating himself to giving each of them renewed purpose.
