Platonic Chain

Nagamine is a young high school student who lives a fairly typical teenage life: hanging out with friends, attending class, and falling in love with a wonderful boy. But when she enlists in the galactic army, who is desperate for candidates to fight an alien war, she finds herself drifting farther away from her first love, Noboru. In the depths of space, where a simple email takes eight years to be delivered, will their love truly flourish, or simply fade away?

Surrounded by water and a world of pollution, oppression, and never-ending rain, the city of ECOBAN feeds off of the surrounding pollutants to sustain life on this seemingly last continent on earth. Shua, a man thrown out of the city, misses the blue sky and now fights to cast down light on this cloud covered island, while uncovering figures from his past.

Whilst hunting for a place to live the two Nanas again cross paths. They decide to share a flat and become best friends in no time.
