Kisaragi Nadeshiko

Kisaragi Nadeshiko, created by Phineasmon302, is the youngest of Kise Yayoi's three future children with Kisaragi Gentaro, the main character of Kamen Rider Fourze.

Personality
Being just a few years old, Nadeshiko, affectionately nicknamed "Nacchan" by nearly everyone, is still developing her personality, and usually behaves like any infant would, laughing when she's happy, bursting into tears if she is frightened or scolded and being moody if she doesn't get the attention she requires. She tends to fall asleep quite easily, and has shown an odd fascination with outer space.

Etymology
Kisaragi (如月): The old Japanese name for the month of February.

Nadeshiko (撫子, written as なでしこ): The Japanese name for the fringed pink carnation or dianthus, as well as a term used to praise the unadorned, clean beauty of a Japanese woman. She appears to be named after Misaki Nadeshiko, Gentaro's first love.

Trivia

 * The creator's idea of pairing Gentaro and Yayoi came from various Pixiv fanarts portraying Yayoi as a Tokusatsu fangirl and, as such, having her interact with Tokusatsu characters, including Kamen Rider Fourze ones (as the second half of Fourze was airing alongside the first half of Smile), and was cemented with a picture posted by Tomimori Justin (Daimonji Shun's actor) on an entry of his blog.
