A child from another world with no way back, a wandering bard, and an ordinary girl with a special identity - three girls met by chance in a world on the verge of decay.
They travel together, learn to trust and endure loss during the journey, and gradually come into contact with the undercurrent rushing under the surface of the world. In the end, an existential choice is before us: to die with the branches, or to witness new life amidst the chirping of cicadas?
Purpose: To explore how, in a world doomed to decay, three girls find a way for the survival of civilization through mutual bonds and personal choices - not to escape the end, but to confirm the meaning of "existence" itself in the shadow of the end.
