When Will the Sun Rise?

It's the year 21XX and Earth has been under a long everlasting winter for a century now.

Ciel is a young girl whose only memories have been gray skies and snow. She has always longed to see the blossoming of cherry blossoms under a blue sky, the galaxies and stars dotting a dark velvet, colorful leaves falling from tree branches, cicadas crying underneath the beating sun, a rainbow on a sunny day, the world below the clouds, a light shower while the stars are out, and how the world looks when the sun rises or sets. When she gets the chance to enter a secret and suspicious organization called Espoir whose job is to "bring back the sun", she jumps at it- no matter how dark it's other side is. Along with her twin brother and their close childhood friend, together they decide to work as members of this group.

Lawrence is an elite of the elites, and he's paired up with Raoul- supposedly an idiot that barely passed Espoir's qualification exam. Together the two are in charge of examining young students in order to find new members for their group. Both have a dark past and a solid goal, but will they be able to reach it?

Isabelle is the daughter of a rich government official and has always been spoiled. Leron is her caretaker and tutor, always beside her. But Leron has a secret- he's an immortal who is hoping to see the clear sky again, and he'll do whatever it takes, alongside his beloved master.

Long is the son of a government official who has given up on humanity. He works for his future, yet days pass and his boredom does not lessen. His only joy lies in seeing the destruction of those with innocent and pure dreams. Occasionally doing jobs for Espoir, he has no interest in seeing the sun again.

These people meet, each with different circumstances, and tread different paths. This is their story.
