Isaburo Sasaki

As the commanding officer of the elite Mimawarigumi, this noble heir to the prestigious Sasaki family leads with an intense focus on prestige. Though he is the half-brother of Tetsunosuke, he often struggles to communicate his true emotions verbally, preferring the intimacy of mobile texting where he adopts a much softer, "Sabu-chan" persona. He relies heavily on the lethal skills of his most loyal subordinate, Nobume, often motivating her with her favorite treats.
