Shigehisa Fuwa

Shigehisa Fuwa is a rich ex-ambassador to whom Sachiko Kasukabe was in deep debt. He has a deep-seated grudge for the Kasukabe family. Each time Fuwa appears, he tries to give Hayato and the cafe staff a hard time for his petty grudge. His grandson even brags that Fuwa has ties to the police so he can do as he pleases as he causes trouble for Hayato. (Source: Goddess Café Terrace Wiki, edited)
