A Kiss Like Two Birds in Flight

The FRANXX they pilot together is named Strelitzia.

Strelitzia has two meanings. The first is: No matter when or where, never forget that the person you love is waiting for you. Legend has it that a girl died while waiting for the boy she loved, and the boy gave this flower to passersby, asking them not to forget their loved ones back home.

The second meaning is a bird that can fly to heaven, carrying all kinds of feelings and longing there. It is said to bring thoughts of the departed to them. "They say it's called the lovebird. That kind of bird has only one wing. The male and female are a pair, and they can only take to the sky by leaning on each other. Incomplete creatures. But why is it that I think that way of living is beautiful?" - Darling in the FranXX

This is a continuation of Darling. I'll carry on their story.
