Despite Rintar? knowing the location of the IBN 5100, Kurisu is against him trying to steal it, as it most likely won't change the world line. Instead, she suggests that Rintar? stakes out the location in order to find FB, with Moeka deciding to join him. As they observe the IBN 5100 being taken out, they follow it as it is passed along to several people, including Tenn?ji, before it ends up on a plane towards France. Rintar?, Moeka and Kurisu confront Tenn?ji, who reveals himself to be FB, killing Moeka before taking his own life. Rintar? uses Tenn?ji's cell phone to finally cancel out Moeka's D-Mail, returning to a world line where both Moeka and Tenn?ji are alive and he possesses the IBN 5100. As Rintar? gets Itaru to hack into the SERN network to erase the data they have on them, he comes to the sudden realisation that he needs to undo an additional D-Mail: the one that prevented Kurisu from getting stabbed.
