Only to wake up in an alternate universe, inside someone else's body. He finds out that the person is called Tess. Tess is a troubled spoiled rich kid. At the hospital, Talay meets another nurse from her universe, who has also transmigrated there. She explains the existence of the two parallel universes and emphasizes the need to find the “Cotua-Porta”. She also reiterates that there may be some deep connection between Talay and the key. When Talay contacts Tess' friends, he runs into an elementary school friend, Tun. Upon meeting Tun, Talay notices some oddities and realizes that the original Tun's soul has also transmigrated.
