Sawashima Himeo

Meet Himeo, an esteemed university student hailing from the sophisticated mansion adjacent to Mitoko's apartment. As the scion of a prominent real estate tycoon, Himeo personifies the elegance and grace typically associated with a young lady of high social standing.

To Mitoko, Himeo is an aspirational figure—enthusiastic and ambitious. However, beneath this radiant facade, Himeo possesses a dual nature. Her demeanor shifts dramatically depending on her company, revealing an entirely different side in the presence of adversaries.

Himeo harbors a deep affection for Mitoko, often expressing concern for the young landlady—however, this shared concern kindles conflict between Himeo and Osamu, who equally cherish Mitoko.
