Seems like in the next chapter Arisu will try to make Himari reconsider her choice by telling her about his family, that way he can obtain a life card from her.
Now I see why they showed us Nanase's past, she's the next that will die.
Supposing that in chapter one Kitou took dead man's phone.
The speaker said that you can't use your cards on someone who died in an alien invasion, but the dead man from the beninning didn't die because of the game, so his phone is still working.
Hall 4:
- Arisu and Himari exchange life cards
- Doctor give himself another life card from the dead man's phone (they will find out about the second phone)
- To finish life cards before the end of last turn, Kitou will give one of them a life card (maybe to dead man's phone)
- No one can use another life card, except for Kitou's secondary phone. So, in order to ensure win, he's not gonna give a life card to Nurse
- Arisu, Kitou and Himari enters a shelter
Hall 5:
- Kitou gives them a death card with dead man's phone and his phone
- Kitou exchange life cards with dead man's phone
- Arisu and Himari exchange life cards to nullify death card effect
- Kitou enters a shelter
Hall 6:
- Kitou's the only one left at this point
- Kitou exchange life cards with dead man's phone
- Kitou enters the only shelter
- Kitou win the game
