Yachiru-san Grows When Praised
Yachiru-san wa Homeru to Nobiru / やちるさんはほめるとのびる

Yachiru, a mischievous hasshakusama yokai, wants to live quietly among humans, but modern folklore has weakened her powers and reduced her height from 240 cm to 190 cm. Because people often depict hasshakusama as seductive spirits, she struggles to restore her true form and change their perception of her, with little success. While researching horror films at a cinema, Yachiru meets Seiichirou, a devoted fan of hasshakusama legends. She discovers that his praise makes her grow taller and regain her powers, bringing her closer to her original, imposing form.
