4

Izumi Shimomura recovers and is revealed to be an Ajin. She uses her own Black Ghost to attack the one sent by Koji Tanaka that killed her. The Black Ghosts battle each other, with the one controlled by Izumi Shimomura eventually defeating the one controlled by Koji Tanaka. However Sato abducts Eriko during the battle and tells her that he wants to help Kei. Kei decides that he should try to contact other Ajin who may be in hiding, but Sato contacts him first and they agree to meet. Kei leaves while Kaito is sleeping and meets Sato, but before Kei can decide whether to trust Sato, he is shot by a tranquilizer dart. Sato decides that Kei is inexperienced and must be 'educated'.
