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.

In a town blanketed by snow, a place from his distant childhood, Yuichi reconnects with his cousin Nayuki. As she gives him a tour of his new home, he struggles with memories long faded.

After his first day at school, Yuichi is able to stir the memories of Ayu, who happily recalls a promise he made to her years before. But the strange girl who later attacks Yuichi doesn’t seem happy at all.

Yuichi’s attacker claims to have amnesia, and with the gaps in his own recollections and Ayu’s forgetfulness, Yuichi starts to think the town might somehow alter people’s memories.

Ayu still can’t locate what she’s looking for, but Yuichi knows where he left Nayuki’s notes: at the school. When he goes retrieve them, he finds he’s not alone in the hallways - and the other person is armed.

Mai explains why she’s at the school with a sword. The next day, Yuichi sees her almost use it on Makoto! When the incident ends, Mai offers Yuichi a bit of odd advice on how to handle the amnesiac.

Makoto has an appointment to interview for a job at a café. Meanwhile, another encounter with Shiori makes Yuichi late for his movie date with Ayu.

Makoto’s carelessness with a kitten causes Yuichi to lash out. Unfortunately, Makoto’s response to his anger is to run away. Later, Mai somehow directs him to her likely location.

Yuichi finds his feelings for Makoto growing, and his memory offers clues of who she might really be. Meanwhile, a girl named Mishio offers him startling information about Makoto - and a strange warning.

Makoto is growing weaker, leading Yuichi to increase the amount of attention he gives her. Her condition grave, Yuichi recalls Mishio’s words - and he also remembers a fuller picture of Makoto’s past.

Yuichi and Makoto spend a personal moment alone atop a special hill. As she seems to slowly slip away from this world, his only focus is on making sure her wishes come true.
