Yuki Yoshida is designed by Shinobu Tagashira, and she has no information on what inspires the creator to create her at this moment. She has three names: Mael Strom (ninja name), Yuki Yoshida (student name), and Tomonori (nickname taken from how Yuki Yoshida's Japanese characters are read, トモノリ). She first appears in Kore wa Zombie Desu Ka? episode 1, but speaks for the first time in episode 7. Her Japanese actress is Hisako Kanemoto.
Yuki has light green eyes and blonde hair that has a side ponytail. In contrast to Seraphim and Sarasvati's bust size, Yuki's bust is bigger than Sarasvati but smaller than Seraphim. Like Seraphim, her breasts doing the Gainax Bounce. Also, she tends to wear clothes that reveal her buxom bust's cleavage.
Yuki is a cheerful and gentle girl who can easily feel bashful especially around Ayumu. She wants to be a good bride for Ayumu.
Yuki Yoshida meets Ayumu in episode 7 where Yuki saves Ayumu and Haruna from the megalos by killing the megalos with tonkotsu. In Yuki's culture, a kiss between the opposite sex means marriage. When Haruna accidentally pushes Ayumu on top of Yuki and the two exchange their first kisses, Yuki becomes Ayumu's wife.
Yuki Yoshida's main weapons are Tonkotsu Ramen soup which she splashes on her enemies. This is first used to defeat the Megalos who had Ayumu and Haruna cornered in episode 7.
