|This article is about a villain in Kamen Rider 555.|
Smart Lady (スマートレディ, Sumāto Redi) is Smart Brain's 'mascot' who works closely under the company's chief and helps develop Orphnochs. She never exhibits any Orphnoch powers in the series, and her species is left ambiguous despite her association with butterflies of the Morpho genus. She acts friendly and frisky towards the many workers at Smart Brain, although she doesn't realize that no one enjoys her company.
She survived in both the TV series and the film, although she is left unemployed in the series finale after Smart Brain crumbled in the aftermath of Yuji Kiba's death.
Though Smart Lady did not reappear following the end of 555, she has been homaged twice by the appearance of her signature blue butterflies, first in the backdrop for the A.R. World of Faiz in Kamen Rider Decade, and again accompanying the transformation of the Great Leader of Shocker, in the form of Takumi Inui, into Kamen Rider Faiz as seen in the third and final episode of D-Video Special: Kamen Rider 4.
