Looks: Black hair, black eyes, and pale skin with a near-to-flat chest. Pic:

That above is basically her but with the red in her eyes and also on her choker, only, are instead black.  As for her choker's motif aka the flower, it is instead a skull one.  When she wears something formal, it is a blood red dress shirt under a black blazer with a black tie, black dress pants, and black dress shoes. As sleepwear, she wears long-sleeved black shirts that are a little big on her with one of her black or grey jackets, black shorts, and black socks.  Dark blue hat, dark blue goggles, and dark blue scarf that hides her goggles when not wearing it on her eyes. Yoruko also wears black gloves.

Personality: Strict, Tsundere, Introvert at meeting new people but the opposite after knowing them for a week. She will be blushing when complimented or flustered with people finding out she writes fanfiction, which she tries to hide.
Likes: Dōjinshi, video games, creating new strategies to duel, chocolate, Horror, and Science fiction. Yoruko loves to write fanfiction about her fellow students and also loves to secretly ship some.
Dislikes: The opposite and people who think she's high and mighty or weak.

Duel Disk:  In 5D's, she has

but in an icy blue color when using her Ice Barrier cards, and then all of it is silver when using Genex cards while it turns silverly blue when using both of these two types. This happens with Triarm changing the color for their (Yoruko's and Triarm's) Monster allies aka her monster cards. It behaves like those taken from the Duel Runners. In GX, she has this duel disk to support her buds aka Crow, Jack, and Yusei, along with Akiza, when she is away at Duel Academy, because her Duel Runner is on campus, but hidden. She soon gains the one in the fourth season, but retains the icy blue of her previous disk. Also, the shape of it is a combination of a dragon and machinery.

Deck: Ice Barrier/Genex

For Genex, he's Yoruko's most trusted one that is her main Duel Spirit while Trishula is her other one.  Anyway, here's Genex Ally Triarm!!!

Biography: Yoruko was born on a Lunar Eclipse with her twin Ichigo to Isshin and Masaki Kurosaki. Isshin taught Yoruko how to control her moon sight and how to detect someone's soul. After her mom passed, Isshin married Ryūken Ishida and Uryū became Yoruko's stepbrother then trained together. Yoruko got into Karakura High and got bullied until her brothers came and beat her bullies up. Isshin taught Yoruko how to Syncro and XYZ summon after she lost her extraordinary powers with her brother until she regained them. Then she helped her brothers take down enemies and graduated two months after that. Isshin then told her to go and live in Neo Domino for five years.
Extra: Her Duel Runner is

, her helmet is dark blue with the visor being black, has inferiority complex with her older biological brother. She has permission by Chancellor Sheppard and Seto Kaiba even, who knows about her Turbo Dueling being taught by Yusei and Crow, to have her Duel Runner on campus, but in a storage container that was shipped to the backside of the female Obelisk Blue Dormitory, as to hide the fact that Yoruko is a Team 5D's Turbo Duelist.

Basically, the character this is focused on is from Yugioh GX and his name is Atticus Rhodes, who is the crush I crave to be played in this book, especially with him Yandere.
