Psalms of Planets Eureka Seven: Good Night, Sleep Tight, Young Lovers

Renton, the son of scientists, grows up alongside Eureka, a girl who cannot survive under sunlight. The two form a deep bond, but one day, Eureka is taken from him. Unable to stop it at the time, Renton swears to save her. He joins the military and, due to his skill with the bio-mechanical armor system Nirvash, is quickly assigned to the First Mobile Forces' Independent Youths Unit 303. What he doesn't realize is that a larger scheme is unfolding-one tied to an ongoing alien invasion, with both him and Eureka at its center.
