In all actuality this is a really crazy moment, like Nina has no self-preservation instinct at all. Its a beat that plays on many earlier instances of Nina physically getting in the way of Momoka when she either turns away or runs away. I think it also ties into the "leaving no escape routes" concept brought up earlier in the episode. By placing her life in no small way in Momoka's hands. Its the conclusion of Nina cutting out every possibility except for their band succeeding, something that can only happen if she still has Momoka.

Here are some things inherent to the world around you. They can be found in nature, in the home, or in you. They may be a disease, an animal, or a person. All at once. You can speak to them. They might answer. You will not understand each other. The ground under your feet will flourish and your neighbors will suffer for it. They will live in your eyes and your ears and they will gorge themselves on your senses. Your wife was missing for a month; here she is sitting next to you, she is beautiful, and did she ever really leave? These things will bless you: they will comfort you, give you everything you ever truly needed, until you dissolve in your joy. The rainbow you saw at the waterfall had it's colors backwards. Your grandmother died last year,but she is your age and she lives in your house. These things do not seek to harm you. They don't seek anything at all. These vibrant, fascinating horrors are in every nook and cranny of the earth. They are the closest thing to Life itself and they do not care about you. You can not see them. You have the terrifying pleasure of living with them.
