- Kokoro Library
*: Also romanised as Sun Joldy. The sisters' late father. A member of the third squad. He lost his family in a raid. He speaks in a very formal manner which causes good-natured teasing among his comrades. He is very caring and helpful. He feels it is his duty to protect the people of his city. He does not approve of fighting but condones it if it is absolutely necessary to protect the city. Uezawa finds his ideals to be
immature . After the war, he helped to rebuild the bridge and spent time in the mountains, living in a cabin and growing vegetables. He shares Kokoro's skill of creating rainbows with a watering-can. Like Shindou, he understands the importance of books and worked to create a library, which he named Kokoro, meaning 'heart', which he discovers is also the given name of Shindo, his future wife.;: An
android who sacrifices herself so that her power source can be used to blow up a bridge, halting enemy advance. She does not appear nearly as human as June, a later model, and has a more mechanised voice. She wishes that in the future, her kind will be used for helping people, rather than battle, a dream which comes true.External links
