"There's nothing I can do to make a difference. Wars will be fought. People will die," Takeru said. "I'll never matter." He didn't know how wrong he was. Because Takeru has a very special place in this universe. And he doesn't know how special until he meets a beautiful girl who falls from the stars. Hikari seems to have no memory of who she is (or, for that matter, where her clothes are). So Takeru takes her into his care. And that's when things get nasty. For Hikari is not like other girls. Her name may mean "light", but she has a dark history-and an even darker future. One that will change Takeru and his friends forever, and show them all just how beautiful yet cruel this universe can be!
