This episode is nicknamed Kana's episode.
Rakka dreams, but is waken early by Kana, whom she promised to help out. They take out the trash, and Kana fights once again with the crows. Then she shows Rakka the Old Home clock tower she's trying to fix, but they have to hurry up to get into town afterwards, because Kana has to be on time at her workstation, the clock tower of Guri. Rakka meets Kana's employer Oyakata and helps Kana to clean up the tower. They have a conversation about crows and the Wall on the balcony outside the tower before they head back to Old Home.
