Yuichi hasn’t seen his cousin
Nayuki in years. Now that he’s back, all knowledge of ever visiting has vanished. He tries to adjust to the vaguely familiar surroundings, but the gaps in his memory haunt him as time grows short. The pieces of the puzzle have appeared – an eerily silent beauty with blazing tresses, the mysterious girl with the winged backpack, and the sword-wielding demon slayer – but it’s up to Yuichi to discover how they fit together.
As a young child, Aizawa Yuuichi had often visited his cousin in the city; however, something drastic happened to keep him away for seven long years. Now, Yuuichi returns, his memories of those days are simply gone.
Settling into the wintry town, Yuuichi comes across several young girls, all of whom are connected to his past. As he befriends them and continues to interact with them, the long forgotten memories from his childhood begin to resurface…
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.
