Asuka Langley Soryu
Kaworu appears in the twenty-fourth episode of "Neon Genesis Evangelion". A secret sect called Seele, and a group called Commission for the Instrumentality of Mankind sent him to the headquarters of the special agency Nerv to carry out a mission as Fifth Child and the replacement for Asuka Langley Soryu, who became unable to pilot Unit 02. Soon after arriving in Tokyo-3 city, Kaworu has a premeditated meeting with Shinji Ikari, Third Child and Eva-01 pilot. He becomes friends with him, showing an unconditional and sincere sympathy towards him. His position as a pilot allows him to enter Nerv without impediment, but he arouses the suspicions of Misato Katsuragi, a major in the organization's operations department. He is subjected to a synchronicity test with Unit 02, obtaining a result so high it astounds the organization's entire staff. He can arbitrarily vary his rate of synchronization with the mecha. All data about his past is erased to conceal his true identity. Misato discovers that he was born on September 13, 2000, the day in which an enormous calamity called the Second Impact occurred at the South Pole, caused by the first of a series of enemies called Angels. He is revealed to be the seventeenth Angel and "last sacrificial messenger", named Tabris. The soul of the first Angel, Adam, is implanted in him. Seele, who captured Tabris when he was still in an embryonic state, "recovered" it. Unlike the other Angels, he can develop feelings close to those of humans and communicate with them. Once in the headquarters, he comes into contact with Rei Ayanami, pilot of the Eva-00, in which the soul of another Angel is implanted, and confesses to sharing his nature as a hybrid.
