Towa runs back to Setsuna to save her and asks if she was okay and apologizes to Setsuna for leaving her. Setsuna calls out to Towa as she falls down. Towa ask why at that moment did she let go of Setsuna's hand.

Towa explains she and Setsuna were always together and they got along so well. Towa and Setsuna happily watch the sunset together. As Towa and Setsuna are walking, Setsuna eats the fruit and says it's yummy. Setsuna accepts the fruit as she thanks Towa, who is happy. Towa and Setsuna land on the ground and Towa asks Setsuna if she wants the fruit. As Towa and Setsuna are falling, Towa notices a fruit and grabs it. Setsuna tells Towa to wait up as she jumps after her. As Towa and Setsuna are on a tree, Towa tells Setsuna to come on before she jumps off. Towa and Setsuna run through the forest and licking water from a stream and laugh as they lay down. Towa narrates that when she was little she had a younger twin sister Setsuna and they lived in the forest for the longest time. She steals two of them from Setsuna and a young bounty hunter named Moroha, and the three are dragged through a portal to the modern era.
