Aoba and Mink head further into Oval Tower and find data on Toue's experiments. Aoba finds out that Mink means to kill Toue, but before he can do anything, they end up being chased and have to seperate. Suddenly, Sei appears in front of Aoba. He tells Aoba that he's been waiting to meet him... but who is he?
You can't kill me, either. 
You're alive, yet dead.
ولا يمكنك قتلي كذلك. أنت حيّ لكنك ميّت
Du kannst mich auch nicht töten.

No serás capaz de matarme. 
Estarás muerto en vida.
No serás capaz de matarme. 
Estarás muerto en vida.
ni entraîner ma mort.
Não vai poder nem me matar.
 Você está vivo, mas morto.
