Along with Otto and Sette, this dual sword wielder was one of the last Numbers to be completed. She and Otto were created while using the same genetic material as a basis. That plus the fact that they both belong to the same taciturn type makes Deed and Otto very close to one another. When directing herself to her older sisters, Deed always presents a very polite behavior. On another note, Wendi dislikes her and Otto because of their always-serious personalities.

In episode 24, after being temporarily knocked out by Teana, she regained consciousness and attempted a surprise attack on Teana. Her attack failed, as she was swiftly knocked out by Vice Granscenic's snipe shot from distance.
