Are the woes of the present meant to be endured for the promise of a better future or to atone for past wrongs? In a captivating epic of love, fate and faith, seven young people must struggle with this spiritual puzzle as their alien past lives threaten the future.

Rin knows almost everything now, but he's keeping it to himself. When he met the others, Rin lied, claiming he was Shukaido, the age difference due to being reborn twice.

In truth, Haruhiko is the reincarnation of Shukaido, and Rin has made sure he knows the reason behind their age difference--Skukaido's treachery, which left Shion alone on the moon for nine maddening years! Shion's obsession to protect Earth has been passed on to Rin, who is intent on destroying the Moon Base and all traces of their potentially Earth-destroying past.

Overwhelmed by his past life, Haruhiko has cut himself off from everyone. When Tamura insists on talking to him, he sees more than he bargained for--including Haruhiko disappearing in front of his eyes! Having teleported to a river, the distraught Haruhiko jumps in! Issei and Sakura happen to spot him and try to save him. Will Issei make it in time?
