Mayumi Nishikino

Mayumi Nishikino is the sharp-witted, glasses-wearing office worker who calls Kawai Complex home. Beneath her biting sarcasm and ever-present wine glass lies a woman repeatedly burned by love, whose cynical exterior masks a genuinely warm heart. She playfully brands herself a 'youth destroyer' as she meddles in the budding romance between Usa and Ritsu, yet her true devotion to her housemates is never in doubt.
