The infamous school journalist, Hiyono is the bubbly and energetic sidekick of Ayumu, always stuck to his side. Very clever and a quick-thinker, her confidence borders dangerously on overconfidence. She is extroverted and is Ayumu's polar opposite, serving as one of the series' few comic-relief characters.

Her skill with computers are as amazing as her hacking abilities and she has access to over one hundred resources. She blackmails Wataya often, and is very fond of Ayumu's cooking. Hiyono is also one of the few who whole-heartedly believe in Ayumu; she also has a great deal of faith and loyalty in him that carries on for the whole series. She attends Tsukiomi High School alongside with Ayumu Narumi.

The cheeky 10th-grader becomes further embroiled in the mystery when he is mistaken for the prime suspect in a murder at his school. Led by Ayumu's sister-in-law, Kiyotaka's wife and fellow detective, Madoka, the investigation into the murder gives Ayumu a chance to clear his name. But in doing so, he not only uncovers ties to the Blade Children but also more questions than answers about who and what they are.
