|» Episode 13|
The haibane of Old Home go into town to buy Bell Nuts for the New Year Festival. Reki runs into Hyouko and gives him one early. Hyouko and Midori tell Rakka about what happened, and Rakka convinces them to help Reki.
Rakka figures out some of the sign language, which she shows to Washi. Washi tells her about haibane having a true name and gives her both her own and Reki's. Reki stays at Old Home during the festival while everyone else goes into town to exchange Bell Nuts. Rakka meets Midori, and they both run out to Old Home to get Reki to watch Hyouko's response, a firework. The others climb the Hill of Winds to whitness the wall realeasing their memories.
