Earthian

終焉的序章

Chihaya 和 Kagetsuya 在法國搜尋墮天使 Sapphire，同時對來訪的賓客隱瞞秘密。

Chihaya and Kagetsuya are staying in France for their current assignment, and lately Chihaya has been having some disturbing nightmares. As Kagetsuya tries to console his partner over breakfast, Aya and Miyagi show up on vacation, and decide to stay in France for a short while. Chihaya and Kagetsuya's mission is to locate the exiled angel named Sapphire, who has been hiding on Earth ever since his wings became black with cancer. Chihaya discovers Sapphire's whereabouts, and, learning about the former High Angel's predicament with some shady dealings, he lets himself become involved, much to the dismay of Kagetsuya, who knows that every time something bad goes down with the Earthian, it is always Chihaya who suffers. The partners struggle to help Sapphire while keeping everything a secret from their guests, but Chihaya's exceedingly strange behavior has not been lost on Aya, and she begins to make some deductions of her own. Both she and Miyagi are well aware of the fact that Sapphire's disappearance has not been taken lightly back in Eden, and as it is, any fallen angels are considered to be a huge disgrace. In the midst of all this, Chihaya is also hiding a secret of his own; one that has to do with the frightening dreams he has been having. His fears are eating away at his heart, and he worries that what happened to Sapphire might be the same thing that caused the abnormal color in his wings and hair. (Source: Wikipedia)

Chihaya 潛入 Dr. Ashino 的實驗室，營救黑天使兒童，並遭遇武器 Messiah。

Picking up where the 1st OVA left off, Chihaya and Kagetsuya are trying to infiltrate Dr. Ashino's lab in order to rescue two black angel children who are being held for interrogation by the mad doctor. The pair split up to search for the hostages, and while wandering through the corridors, Chihaya discovers, locked away in a side room, a black-winged angel like himself, attached to wires extending from the walls. The angel's name is Messiah, and Chihaya, desperate to get the dormant figure's attention, exposes his wings at the window of the room. Messiah's memory chip, still in the process of being encrypted, takes in the image of Chihaya's transformation and fills Messiah's mind with strange emotions. He is compelled to approach the angel on the other side of the glass window, but cannot get out of the locked room. An alarm begins to sound, and Chihaya and Kagetsuya meet up again, Kagetsuya carrying the two children. They are forced to evacuate the lab immediately, as it is about to explode. Elvira, the mother of the children, pulls up in her car and help them get away. Chihaya is deeply troubled that he was unable to save the black-winged angel. One morning, while watching the news, Chihaya discovers that Doctor Ashino has arrived in the city accompanied by a strange man in a trenchcoat. Chihaya immediately recognizes the man as Messiah. Ashino has been having dealings with the military, and was commissioned into creating the ultimate weapon of destruction: Messiah. However, he is not in it just for the money. Troubled by the fact that Taki abandoned him, Ashino is plotting a revenge against the entire world, who stood by despite his suffering. (Source: Wikipedia)

彌賽亞尋找千早，而芦野試圖將其捕獲以進行武器化。

Chihaya is reluctant to accept Messiah's disappearance, and no matter how Kagetsuya tries to comfort him, he can only ever think of the android whose wings were like his. Messiah, in the meanwhile, is making his living carrying out errands for a club of drug dealers. He feels accepted by these people, who are appreciative of his physical strength, but longs to find Chihaya again. Using his connection to the world's computer database, Messiah searches for his friend. Chihaya, also online, discovers Messiah's call, and rushes to meet him in the sky. However, Ashino has also been tracking Messiah, and he sends in men to capture the runaway android. Ultimately, Messiah needs to choose between staying with Chihaya and learning more about the emotions that confuse him, or give up his freedom in exchange for the assurance of Chihaya's safety, and become the weapon of destruction he was intended to be.
