Miki Tachibana

Miki Tachibana is one of the most quietly captivating figures in the series. As the mother of Alex and Sylphynford, she consistently appears in traditional kimono attire and possesses such a youthful look that Umaru once mistook her for Sylphynford's older sister. What truly sets her apart is her extraordinary perceptiveness — she is among the very few characters to see through Umaru's double identity as UMR, yet she chooses to keep that secret with gentle grace, adding an air of elegant mystery to her character.
