Hiyama Shunka

Hiyama is an extremely precise woman who follows her life second. However, she seems to have a paralyzing aversion to solitude , as seen when she lost her normally calm composure after Akoya Seishu criticized her for her performance in their fight. She is completely bonded to Akoya Seishu, in a way far beyond Stockholm syndrome , and sees him as her savior.

Hiyama was appointed executive director of Wakasa Life Insurance six years ago, after the death of his father that same year. As she lacked work experience, she got help from her cousin , who was vice president, and soon became irreplaceable for her. However, just a year later, he attempted to assassinate Hiyama in an attempt to take control of the company himself. However, her cousin was killed by Akoya Seishu before he could kill her. From that moment on, Hiyama saw Akoya as his savior and helped him in his determined quest for "justice".

Hiyama has a perfectly accurate internal clock that allows him to mentally analyze and calculate numerical problems with superhuman capabilities (only a handful of cases globally are at his level). For example, she is able to calculate a wrestler’s breathing pattern by analyzing it with her internal clock.
