Yachiru-san wa Homeru to Nobiru

A Hasshakusama youkai named Yachiru resides in the human world. Due to the widespread belief that her kind is sensual rather than frightening, her abilities have diminished, and her height has decreased from 240 cm to around 190 cm. She attempts to change this perception but continues to face setbacks. While watching horror films at the cinema to better understand them, she encounters Seiichirou, a young man who admires Hasshakusama. Yachiru notices that her height increases to its original size whenever Seiichirou compliments her.
