Go Nagai's The Devil Lady

Jun Fudo just seems to be going through the motions in her photo shoot, although the photographer seems to think she is doing wonderfully. Jun is later attacked by a werewolf which awakened the Devil Lady in Jun.

Jun is called upon to handle more than she ever imagined. She exhibits abilities that were unimaginable by the Human Alliance (HA), to meet an unexpected challenge. Jun still cannot believe what is happening and wonders if it was all just a nightmare.

The devil-beasts cannot understand why Jun holds onto her inferior human side, and now seek to punish her for it. They find out about those close to Jun, picking Kazumi Takiura as an easy target. While Jun is able to find out in time to save Kazumi, she is unable to stop the beasts from brutally killing Kazumi's parents.

Jun is still reeling from previous incidents, and reflects on how she was different from others. She falls into self-pity, as she is seemingly being held captive by the HA, the very organization that utilizes her to destroy other beasts. Jun is leery of people in shadows, thanks to her last encounter. A new beast with an unusual characteristic is discovered.

Thanks to Asuka, Jun has an unplanned reunion with an old friend from high school, Aoi Kurosaki. Their friendship did not last as Jun and her ex-classmate had a difference of opinion on what the relationship should be. Meanwhile, Kazumi feels a little left out, however Jun's encounter only strengthens her bond with Kazumi.

Jun experiences a love-hate relationship firsthand, when she meets Hitomi Konno, a competitive supermodel who idolizes her and loves cats.

With each transformation, there is an increased risk that Jun will lose her human side. Recent events take Jun's thoughts back to the story her grandfather told her about the Grim Reaper hoping she would go to bed, leading only for Jun's curiosity to increase.

The HA continues their attempt to keep the general population from discovering the devil-beast phenomenon. A broadcaster attempts to release the news of the devil-beasts. Jun is introduced to Dr. Jason Bates, an American from the Samuelson Lab.

Jun dwells upon her previous failure and the disappointments of Asuka and Jason. While looking into a store window, Jun feels someone watching her. Jun finds herself in the park in a photo shoot. Kazumi is interviewed and photographed.

A large fire at the Sakura Housing Complex looks suspicious, as firemen are surprised to find a survivor in the rubble. Jun disagrees with Asuka upon believing that the survivor is a devil-beast since survival would have been impossible otherwise, especially much to the fact that this survivor is a child.

A department store executive disappears after being falsely accused. Unfortunately, he is not the only one who disappears. Jun is called in to handle this situation in an all too public department store building, all just in time for Christmas.

Jun has recurring visions of a devil-beast world. After running into Jason in the streets, Jason invites her to a cavern bar, where he accuses her of enjoying the kill, and yet calls her weak mentally and physically. The authorities are finding victims with their face missing, while Jason still obsesses over Jun's and some of the other devil-beasts' ability to manifest the giga-effect.

Jun has a photo shoot with inexperienced model Takai, a high school student that is more intimate than usual. Jun shows interest in a phone call that Tatsuya Yuasa receives during the photo shoot. After the photo shoot, Jun acts inappropriately with Takai and shows regret. Jun later sees Sakazawa speaking to Kazumi and Yuasa in separate incidences.

Sakazawa remembers his life before the beast obsession. Kazumi goes missing and Jun becomes focused on finding her. Meanwhile, Kazumi realizes she has been used, but is not quite sure for what. The HA has their hands full with another beast, and receives unexpected help from Jason. The battle between the beast factions now begins to accelerate.

Kazumi's conversation after a photo shoot plants the seeds of remembrance regarding her parents' death. Bodies begin to show up on top of lamp posts, utility poles and other odd places. Sakazawa's warnings replay through Kazumi's mind. Crows show up in the oddest places.

The dead bodies on top of traffic posts continue. The HA begins to have trouble keeping the secret of the devil-beasts. Maeda gets directly involved in the fight against devil-beasts. Kazumi's voice is a godsend to Jun.

Satoru continues to recruit beasts to his cause, and his statement that Jun is hated by the humans seems to be manifesting itself. Also, Jun appears to be losing control of her beast side. She calms down and regains her human consciousness when Asuka returns.

The battle between humans and devil-beasts is worsening. And Asuka's behavior is drawing the attention of the HA.

Kazumi is still getting used to the idea of the beasts in the open. She worries about being able to trust other devil beast other than Jun. Yuasa is surprised to see Maeda after their last conversation, and Maeda becomes more suspicious of Asuka. The battle with the beast is no longer a secret, as Yuasa and Jun temporarily relive a normal work day.

In America, Asuka gets a new private secretary, Captain Izume Kogure. Jun grudgingly meets some old acquaintances as well as a new more powerful associate of Satoru's recruited devil-beasts. Maeda discovers Asuka's secret past. Jun and Satoru have a battle of the wills.

Maeda discovers the truth about the RNA Transmutation Innoculation and informs Jun. Kazumi becomes closer to her new friends, but still wants to be with Jun.

Jun receives help from an unexpected source, that of Kazumi, when defeat is imminent. Kazumi remembers her first meeting with Jun. Hostility increases between humans and the devil-beasts, as Satoru continues to round up his army. Izumi is concerned about Asuka. Jun inspires a fond childhood memory in Kazumi, causing Kazumi to want to help Jun in any way she can.

Jun is legendary among the gentler beasts as the champion of their kind. Kazumi's influence inspires hope in her recently found friends. They expect Jun to rescue them. Asuka's plan becomes more apparent. Jun faces a beast with unexpected strength.

HeartJun befriends a new young companion who understands Jun's past too well. Unfortunately, Chiyoko does not understand why Jun had to do all that she did. She does not understand the fine line that Jun must not cross.
