Hiroshi Harune is the father of Aira, Itsuki, Eru & Uru, and the husband of Omi. He is the head chef of the Haru no Sorato bakery. At first, Hiroshi was extremely opposed to Aira doing Prism Shows because he wanted her to stay a young girl wearing frilly clothes forever. However, after learning the appeal of Prism Shows, he not only allowed her to do Prism Shows, but also cheers her on from the shadows. He is quite an over-protective father, often doting on Aira while oblivious to the latter's discomfort and mostly acts as comic relief, but in very rare moments he is the voice of deep reason.
