Tập 4: Messiah tìm kiếm Chihaya trong khi Ashino cố gắng bắt giữ anh để chế tạo thành vũ khí.

4

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.
