Omg I've seen spoilers to the new DR3 episode so prepare for spoiler starting now. I don't think kirigiri is actually going to die as her NG was Naegi surviving round 4 She was poisoned but if you look in the corner of the screen when they see kirigiri poisoned up I'll see the antidote made by none other than Seiko. Now I know what your all thinking that it didn't work on Bandai so why will it work now, well you see Seiko most likely improved it so it has a higher chance of working. So NaegixKirigiri lives on!
