This is when Amano and Gasai swoop in, armed with submachine guns, to rescue Ninth and move on to the next phase of the plan.
Eleventh seals himself in a bank vault.
When they can't open the door, Ninth turns on Amano, aiming to get revenge for her eye, and for Nishijima.
Amano manages to beat Ninth.
The bank Eleventh is in was owned by Gasai's parents. The vault has a retinal scanner that will only open for Eleventh, Gasai's parents, and the real Gasai Yuno.
Nonetheless, she is able to open it and kill Eleventh.
