Clannad After Story

The 'girl in the sky' is a legend passed down through the ranks of one special family. Armed with the magical puppet skills he learned from his mother, Kunisaki Yukito follows in her footsteps, traveling from place to place, ever searching for that girl in the sky, ever chasing after that legend. His journeys have led him to a small costal town where he meets a girl that has a peculiar interest in him -- could she be the one? As events slowly start to unfold in front of his very eyes, Kunisaki Yukito finds himself amidst a story that spans a thousand summers...

It's been seven years since Yuuichi Aizawa returned to the city he once lived in as a child. Though many things happened to Yuuichi in his past, he can only remember bits and pieces. His parents left Yuuichi in the care of Akiko once again, and this time, he will attend the same school as his cousin Nayuki. Many different girls appear before him, and some of them seem to know him from his past. Yuuichi must now recover his memories of the dark secrets that he erased from his heart, before he loses his precious ones.
