As he pulls off the pictures of the blue sky from his ceiling, Yorito remembers how he had told Matsuri about wanting to turn everything back with his sister. On that night, he had arrived home after seeing Matsuri and admitted to Aono that he had found about everything she was hiding from him. However, he also explained that he wished for her to become happy and suggested that they leave this town so they can start over from scratch. Mayuko meanwhile is also planning on leaving town with Takeshi because she feels that she might stop Matsuri if she stayed. When Matsuri tells Mayuko that Yorito returned to everyday life, Mayuko comments on how he’s made a painful choice. At school, Mana remembers how determined Yorito had previously been to confront his sister, and she now finds him on the rooftop taking pictures of the sky again. Yorito explains that today is special because the air is clear, meaning that the sky is bluer than normal. After Mana thanks him for making Koyori happy by returning home to Aono, she starts to say something else, however he cuts her off by saying that he doesn’t want her to ask him about anything. Mana tries to make the case that she’s quite flexible to new things, but Yorito still refuses to tell her anything and claims that he’s okay. Hearing this, Mana at first says that she won’t worry anymore, though it becomes clear how she really feels when she tells him to think more about the feelings of other people.
Back at home, Aono is paid a visit by Koyori and tells Koyori to not come anymore because they’re leaving this town. Koyori wants to know where she’s moving to, and Aono only says that it’ll be far away where their past and memories can’t reach them. It depresses Koyori to hear this, but on her way back home, she passes by a bookstore and gets an idea. She returns later that afternoon to beg Aono to teach her how to make more origami, just for today. Her older sister meanwhile is out with her friends and Sae, though she pays no attention to them and instead stares out the restaurant window. The girls notice that Mana has been acting strange today and start to tease her about it, so she tries to shut them up by telling them not to talk about Yorito. Oddly enough, they don’t seem to know who Yorito is, and Mana interprets this as more teasing, so she leaves angrily. When her friend Touko finds her again later, Mana apologizes and asks what Touko thinks of Yorito. However, Touko truly doesn’t know who Yorito is. Mana attempts to show Touko the picture of him from the hospital, but to her shock, both Yorito and Aono are gone from the image. This combined with how Yorito had called today special and said that she’d understand by evening gets Mana worried enough to rush back to school.
To Mana’s relief, she finds Yorito still on the rooftop taking pictures. As the two admire the evening sky together, Yorito comments on how they can’t see the same sky twice – even if it looks the same, it’s a completely different one. After Mana then tries to confirm that Yorito is who he claims to be, she holds out her hand and asks him to grab it. She wants to be able to feel it to reassure herself that he’s really here and not a ghost. When he asks her what’s wrong, Mana tells him about how her friends had all forgotten about him and tries to get him to tell her that this isn’t possible. She is met with only silence from Yorito. Despite this, Mana holds onto all her memories of her daily life with him and repeatedly refuses to forget them. Yorito then lets go of her hand and disappears at the same time that Mana closes her eyes. Back at the Morimiya home, Aono had been watching Koyori make origami and had apologized and thanked the younger girl. Koyori really didn’t want to part with Aono since they’re friends and ended up crying into Aono’s arms, but she is now fast asleep. As she stares into the night sky, Matsuri explains that illusions are dreamlike – although they certainly existed there, if you wake up from the dream, they will disappear from your memory before long. When Mana opens her eyes again, she finds herself crying uncontrollably and doesn’t know why.
On this same night, Mayuko and Takeshi leave, entrusting his sword with Matsuri. Before going, Mayuko comments on how Matsuri looks hesitant when she speaks Yorito’s name and feels that Matsuri at the very least shouldn’t regret this. As she walks away, Mayuko thinks that she might still be happy since she’s not alone and then gets Takeshi to extend his hand so that she can hold onto it as she walks with him. Once those two are gone, Matsuri turns around and faces Yorito. Aono is meanwhile at home alone packing up all the different dolls that Yorito got her when she hears a noise from the front door. She goes to investigate thinking that Yorito is back, but Matsuri suddenly appears – with sword in hand – in the hallway behind her.
I really found this to be quite a sad episode and felt that the rooftop scene with Mana was quite powerful (Honda Youko does a very good job), especially when tied together with Matsuri’s explanation of illusions being dreamlike. Mana adamantly refused to forget, yet in the end, all that she was left with were her tears to signify what she’s lost. She never did find out the truth about him, though it might not have hurt to tell her if her memory was going to be completely wiped anyway. I guess that by doing this and thereby cutting ties with her, Yorito is prepared to disappear forever. Of course, with him being made out of paper and all, I just can’t see Yorito surviving the end of the series unless he somehow gets his body back. More likely, he and Aono and probably Matsuri will all die or disappear in some way. Next week though, we have the next round of Matsuri facing against Aono to look forward to, except this time Matsuri has come prepared with Takeshi’s sword.
