Mika Nitta

Mika Nitta is Yoshifumi's younger sister who once worked as a municipal clerk at a small town office back in their Tohoku hometown. Wildly uninhibited and utterly carefree, she transforms into an unpredictable force of nature after a few drinks, leaving a trail of outrageous antics in her wake. Beneath her rowdy exterior lies a karate black belt, and during her school days she famously entertained herself by hunting down delinquents. After quitting her job, she descended on her brother's Tokyo life, sparking one comedic crisis after another and cementing her role as the series' most energetically chaotic supporting character.
