Christmas is coming up. Alice invites Chise out to London, where they hang out together and go gift shopping for Renfred and Elias.

A surge of magic threatens to kill Chise. Elias takes her to the land of fairies for treatment, while Silky is left to take care of their home.

The Leannán Sídhe begs Chise for her help: Joel is on his death bed, and she can only seem to make things worse. Chise vows to do what she can to turn that around.

Chise is attacked by yukimushi, briefly making her dangerously ill. She and Elias discuss the nature of their relationship.

Lindel finishes the staff that Chise had finished carving. As she finishes, she meets an old friend, who offers her some wise advice.

"Elias, is an odd failure who pretends to be human -- but is it because of his master's words, or because of his distrust for humans, that he stopped communicating about himself? Lindel's alias, Echoes, refers to the to a song aking to the sound of snowmelt, traveling through the wind, causing the blooming of flowers and the dancing of fairies. The magic of the song turns into a mirror the surface of the water Chise peers into. What does she see beyond the mirror?"

Chise and Selkie climb aboard a dragon's back to meet Lindel, to have her own mage's staff made. Frustrated by Chise's acceptance of her being kept as a pet by Elias, he describes the time he found Elias in the darkness. Meanwhile, Elias, who had stayed at home by himself, receives a letter from a sorcerer's college.

Having given up on life, 15-year-old Hatori Chise sells herself at an underground auction, where she is bought by Elias Ainsworth, a not-quite-human mage, for 5 million pounds. She learns that he intends for her to be his future bride, and her world begins to change.

When Moriko's computer breaks down, she asks for help from a certain someone to buy a new one. Before even realizing it, she's agreed to have that person over to her place to build the PC itself! Who's coming over?! Will Moriko successfully clear the "Invite a Guest Over" quest?!

Naho feels relieved now that she has the support of all her friends. On top of that, Kakeru and Naho begin to get even closer. Finally, the day of the athletic festival comes. What do Naho and the gang do to insure Kakeru can enjoy the festival from the bottom of his heart?

Up until now, Naho had been doing everything the letter from the future had told her to do, but is the letter always right? The letter from the future asks Naho to make sure Kakeru doesn't run the relay race at the athletic festival, but what does Naho decide to do?

The letter from the future details the regret felt by everyone for being unable to celebrate Kakeru's birthday. As such, high school Naho and the gang pester Kakeru about what he wants until the big day. On the other hand, 26 year-old Naho and the gang gather at the late Kakeru's grandmother's house to celebrate his birthday, like they had promised in the past.

It's the last day of the school festival. Naho and Kakeru have promised to watch the fireworks together. However, just before they start, Ueda-sama gets in Naho's way. Will Naho get to experience watching the fireworks with Kakeru like her future self did?

Kakeru gives Naho a hairpin. And on the weekend, Kakeru invites Naho to study with him for the upcoming exams. As the pair begin to grow closer together, Naho gets up the courage to invite Kakeru to see the fireworks together with her at the end of the school festival.

Naho is so concerned about Kakeru’s date with Ueda-senpai over the holidays, she can’t help but seem preoccupied and unable to focus on her friends’ conversations. Ever since Kakeru started dating Ueda-senpai, Naho has found it difficult to have a proper conversation with him. Naho regrets not directly telling Kakeru how she really felt the day Ueda-senpai asked him out, but what will she do now?

Naho can't give her Valentine's Day chocolate to Kakeru. Ever since what happened on New Year's Eve, Kakeru keeps putting distance between Naho and himself. But, through all the hardships, Naho refuses to give up and fully intends to tell Kakeru how she feels. And so, the time comes for everyone to face the fateful day outlined in the letters from the past, "Kakeru's Final Day."

Kakeru moves to Matsumoto with his mother mother after she decides to move there for her own reasons. When she passes away on the first day of school after Kakeru transfers, Kakeru blames himself and thus refuses Suwa's invitation to join the Soccer club. Kakeru sees some old classmates from Tokyo, but none of them understand what Kakeru is going through. In the end, Kakeru becomes so distressed that he feels that he has no way out.

Naho got into a fight with Kakeru on New Year's Eve, and never managed to apologize to him before he passed away. At least, that's what the letter from the future says. However, Naho now believes that she's capable of dealing with whatever may come up, and faces New Year's Eve head-on.

It's the athletic festival. Kakeru hurt his ankle during the pole-toppling game, and hid that fact from everyone else. Kakeru tries to keep his suffering to himself, when Suwa and the gang call out to him. Met with everybody's kindness, Kakeru begins to tell them what he's been keeping pent up inside. And then, the class relay begins.

Naho feels relieved now that she has the support of all her friends. On top of that, Kakeru and Naho begin to get even closer. Finally, the day of the athletic festival comes. What do Naho and the gang do to insure Kakeru can enjoy the festival from the bottom of his heart?
