Hiyori is a second-year student at Tomoki's school whose story is detailed in Heaven's Lost Property the Movie: The Angeloid of Clockwork. She has feelings for Tomoki and joins the New World Discovery Club in order to get closer to him.[ch. 34] In reality, Hiyori is an Angel who was first seen inside some sort of sleeping chamber when Sugata went to Synapse. The chamber connects her to her body on Earth, which functions like an avatar.[ch. 24] Sugata is hesitant in letting her join his club, but welcomes her upon hearing the club would receive more funding. Tomoki puts Hiyori through an false initiation to assess her purity. Thus far, only Sugata, Nymph, and Ikaros are aware of Hiyori's true identity.[ch. 35,38]
Hiyori gets rather embarrassed when it is suggested that she and Tomoki are an item; while she likes Tomoki, she has not considered dating him yet, and her presence becomes a source of major discomfort for Sohara, Nymph, and Astraea. This stems from the realization that Hiyori is always kind and caring to Tomoki, while the others seem to only see his "faults".[ch. 36] Eventually, Hiyori manages to confess her feelings to Tomoki, which leaves him in shock as no girl has ever confessed to him before. However, her time with Tomoki is ultimately cut short when a sleepy truck driver runs her over, which causes her avatar to disappear and her existence to be erased from everyone's memories (except for Tomoki and the Angeloids).[ch. 36-38]
Hiyori is later converted to a "Type Zeta" Angeloid who works for the Master of Synapse to destroy the city. She uses a staff, called Demeter[VIII], which has the power to manipulate the weather by changing the air pressure, and thus knocking people unconscious. She is also able to counter-hack Nymph, but eventually loses when Nymph evolves into Aphrodite mode. After she is freed from Master, Hiyori remains on Earth and quits the New World Discovery Club. As she has accomplished her goal of getting close to Tomoki, she leaves him with a farewell kiss,[ch. 40] although she continues to harbor feelings for Tomoki.[ch. 61] She later gives Chaos the ability to fully grasp emotions, at the cost of her own life
