Hope is one of the many forms of Inner Jack and one of the two positive forms it possesses.
Hope was slowly diminishing in season five after Jack has lost his sword and was being overrun by the negative personalities.
In Episode CI, Hope returned to Jack once again after he came back to the Past, when he was sitting under a tree as he saw a ladybug.
- Hope and Care are the only positive personalities of Inner Jack.
- It should be noted that the Japanese word for castle, shiro (城) is homophonically similar to the Japanese word for white, Shiro (白).
