42 years old. A wild, masculine man with neatly trimmed black hair, rugged stubble, and a solid, muscular build. He is fearless and predatory, but in truth, he is prone to loneliness and possesses a strong sense of possessiveness toward those he lets into his inner circle. Though he initially refused protection, he is beginning to be drawn to Ayumi's beauty and strength.

45 years old. An intellectual-looking man with glasses, always dressed in an impeccable suit. Behind his mild-mannered tone, he hides a cold ruthlessness, willing to use any means to achieve his goals. He is Ayumi's former partner and trusted her skills more than anyone else's when he assigned her to guard Makoto.
