Issa Ogiwara

As the president of Ogiwara Foods and the older brother of Sayu Ogiwara, Issa Ogiwara grew concerned for his sister after Yuuko Masaka's suicide, as Sayu was blamed by their mother. Out of kindness and concern for his sister, Issa gave Sayu a large sum of money and instructed her to leave home. Although his actions stemmed from a desire to protect Sayu, they ultimately led to her running away. Following their mother's orders, Issa searched for Sayu, but he always remained attentive to her well-being. Throughout the events, he maintained a polite and gentlemanly demeanor, even towards Yoshida.
